2SHUDWLQJ pump begins performing the operations in the Pumping Program until the
Pumping Program either stops automatically or the pump is stopped when the
‘Start/Stop’ key is pressed, or from any other source. While performing the
operations defined in the Pumping Program, the Pumping Program is referred to
as operating.

3. Setup
♦ Place the pump on a stable surface.
♦ Plug the round connector end of the supplied power supply adapter into the power plug located on the
lower right of the pump's rear. See section 11, Logic Interface: TTL Input and Output, for a diagram of
the rear of the pump. Plug the other end of the power supply adapter into an appropriate electrical outlet.
The pump will be powered when the bottom of the power switch, located on the upper right of the rear of
the pump, labeled ‘1’, is pressed. The red indicator on the switch is visible when the power switch is in
the ‘on’ position. After power is applied to the pump, the pump’s display will flash.
♦ Next the Pumping Program can be entered. Before the Pumping Program can be operated, the pump
needs the measurement of the inside diameter, in millimeters, of the syringe that will be loaded. The
syringe diameter can be entered using the keypad on the front panel of the pump.
♦ Finally, the syringe can be loaded and the pump started.

4. Loading Syringes
The syringe is loaded by securing the barrel and the pusher flange as follows:
1: Loosen the 2 thumbscrews on the syringe retainer bracket.
2: Press in fully the white drive-nut button on the pusher block, releasing the block. Taking care not to
drag the drive-nut on the drive-screw, slide the block away from the syringe holder, providing sufficient
space for the loaded syringe. Then release the white button.
3: Lift the syringe clamp above the syringe holder block. Turn it 1/4 turn and then lower it onto the
syringe holder block. The syringe clamp should be out of the ‘V’ slot.
4: Load the syringe with the barrel over the syringe holder and the syringe plunger towards the middle of
the pump. Place the barrel on the syringe holder block, in the ‘V’ slot, with the barrel flange inserted
between the syringe holder block and syringe retainer bracket.
5: On the pusher block, turn the thumbscrew to make the slot large enough for the plunger flange. Press in
fully the white drive-nut button on the pusher block, releasing the pusher block. Then slide the block
towards the syringe plunger. Place the syringe plunger flange into the slot and against the anti-siphon
plate. When the flange is positioned in the slot, release the white drive-nut button.
6: Lift the syringe clamp to slightly above the height of the syringe barrel and turn the syringe clamp 1/4 turn
back to its original position and then lower it onto the syringe barrel.
7: Firmly push in the syringe retainer bracket against the syringe barrel flange and tighten the 2 thumbscrews
on the syringe retainer bracket. On the pusher block, turn the thumbscrew to move the plate against the
plunger flange.
Ÿ To unload the syringe, reverse the instructions for syringe loading.

5. Guide Rod Collar Clamp (Model NE-1000 only)

WARNING: Do not use the collar clamp as a normal method of stopping the pump. This will cause damage
to the drive nut. Pump Stall is a fault condition and not a normal method of stopping the pump.
To protect a fragile syringe from damage caused by over infusion, use the collar clamp to limit the travel of the
pusher block. Using the hex wrench located in the tool holder on the rear of the syringe holder, loosen, but do
not remove, the hex screw on the guide rod collar clamp, enabling the collar clamp to slide on the guide rod.
Position the collar clamp as required, and then tighten the hex screw on the collar clamp with the hex wrench.
Replace the hex wrench in the tool holder. When the pusher block comes in contact with the collar clamp
while infusing, a stall alarm will occur. The pump motor will be stopped and the Pumping Program will be
paused. If alarms are enabled, the buzzer will sound.

6.1 Entering Values

When applicable, values can be changed by either displaying the current value, then using the arrow keys, or
from a computer connected to the pump. The new value will be stored in the pump’s non-volatile memory,
meaning that the new value will not be lost the next time that power is applied to the pump. The only
exception is when the pumping rate is changed from an attached computer while the Pumping Program is
operating. In this case the new pumping rate will not be stored in non-volatile memory.
A displayed value can be changed by pressing the arrow keys below each digit. If the value to be changed is
not currently displayed, when applicable, momentarily press the key associated with the required value. The
display will show the setting’s current value and its units, if any.
While the current value is being changed, the units LEDs associated with the value, if any, will blink. Except
where noted, the new value is stored, and/or the selected operation takes effect, when either
1) A non-arrow key is pressed or
2) After a 2 second delay since the last arrow key was pressed.
If the new value is valid and different from the original value, the display will blink, indicating that the new
value was stored. Otherwise, if the value was invalid, an error message will be displayed. Pressing any key
clears the error message and restores the original value.
In general, if a parameter has 2 values, ‘off’ and ‘on’, they are represented by the numbers ‘0’ and ‘1’,

6.2 LCD Display

The display consists of a 4 digit reflective LCD (Liquid Crystal Diode) display. This is the general purpose
user display device for displaying numerical data, functions and parameters. The colon (:) is used for
displaying time or for separating function abbreviations from their parameter values. In the upper left corner is
a triangle that indicates valid reception of RS-232 remote communications.

6.3 LEDs
To the right of the LCD are 8 red, round, LED (Light Emitting Diode) indicators. The first 2 columns display
the units of the displayed values. Units are expressed using 1 or 2 LEDs. For instance, ‘mL / hr’ is expressed
by lighting the ‘mL’ and the ‘hr’ LEDs.
‘Dispensed’ indicates that the displayed volume is the total ‘Volume Dispensed’ or pumped.
When ‘Pumping’ is lit (not blinking), the motor is operating, either infusing or withdrawing. If blinking, the
motor is not operating, and the Pumping Program is paused. When the pump is restarted, the Pumping
Program will resume at the point where the Pumping Program was interrupted. When not lit (not blinking) the
pump is stopped, but the Pumping Program may be operating a pause Phase. Starting the pump, when the
Pumping Program is stopped, will start the Pumping Program from the beginning (Phase 1).
‘Withdraw’ indicates that the pumping direction is set for withdrawing. If not lit, then the pumping direction

6.4 Arrow and Decimal Point Keys

Each of the four digits in the display is associated with the up arrow key directly below it. When applicable,
the arrow key is used to increment the value of that digit, or advance to the next selection in a list of functions
or settings.
Each press of an up arrow key will increase the digit by 1, up to 9, and then back to 0. The arrow keys may
also be held down for continuous incrementing of numbers. Some parameters, such as the RS-232 baud rate,
scroll through a selection of values when the arrow keys are pressed. Other parameters have a fixed range of
values, such as some setup parameters that are either turned on or off. In these cases, the arrow key will only
scroll up to the maximum value for that parameter, then back to the minimum value.
When changing the pumping rate units, each press of any arrow key will change the units LEDs to the next
units selection.
When the display blinks, the new value is stored and takes effect. This will occur when a non-arrow key is
pressed or after a 2 second delay since the last key press.
6.4.1 Decimal Point
There are 4 decimal point positions on the LCD display. Each decimal point position is to the right of a digit

change to the default Volume Units when setting the syringe diameter.

7.2 Start/Stop Triggers

The Pumping Program can be started or stopped from three sources: The keypad ‘Start/Stop’ key, RS-232
‘RUN’ command, or the TTL I/O Operational Trigger input. Each can control the Pumping Program’s
operation.

7.3 Operating the Pump

When the “Start/Stop” key is pressed, the Pumping Program begins to operate, starting with Phase 1. If the
current Program Phase specifies a pumping rate, the pump will begin pumping, and the ‘Pumping’ LED will
be lit. The pumping direction will depend on the Phase setup.
While pumping, the pump will pump continuously in the current Program Phase, unless a “Volume to be
Dispensed” is set, or an Event trigger is set. If a “Volume to be Dispensed” is set, the Program Phase will be
complete after the set volume has been infused or withdrawn, measured from the start of the Phase.
The display can be changed by pressing the ‘Rate’, ‘Volume’, or ‘Diameter’ keys.

7.4 Purging

NE-1010/510/511 High Pressure New Era Pump Systems™

Dispensed can be displayed by pressing the ‘Volume’ key one, two, or three times, depending on the current
display.
The volume is accumulated separately for infusion and withdrawal. When the pump changes direction, the
“Volume Dispensed” changes to the accumulated volume for the current pumping direction.
The “Volume Dispensed” accumulations for infusion and withdrawal are reset to 0 when:
A) With the pump stopped, pressing and holding any up arrow key while displaying the “Volume
Dispensed”.
B) A sub-program is selected when the Pumping Program executes a Program Selection function.
C) The syringe diameter is changed.
D) From the RS-232 clear “Volume Dispensed” command (CLD) or Clear Dispense function.
E) The accumulated Volume Dispensed rolls over from 9999 to 0.
F) The pump is powered on.

7.7 Resuming When Paused

If the Pumping Program is stopped before the completion of the Pumping Program, the ‘Pumping’ LED will
blink, indicating that the Pumping Program is paused. While the ‘Pumping’ LED is blinking, starting the
pump again will resume the Pumping Program where it was stopped. This means that the Pumping Program
will continue at the point in the Phase where it was stopped and the ‘Volume to be Dispensed’ will still be
referenced from when the Program Phase first started.
Pressing any key other than the ‘Start’ key will cancel “Pumping Program paused” and the ‘Pumping’ LED
will stop blinking. When the Pumping Program is started again, it will start from the beginning (Phase 1).

7.8 Pump Stalled

WARNING: Do not use Stall as a normal method of stopping the pump. Continuous stalling will cause
damage to the drive nut.
When the operation of the motor is impeded due to excessive force needed to drive the syringe, or when then
collar clamp position is reached, the pump will stop, pausing the Pumping Program, and a stall alarm will

occur. The display will show , the ‘Pumping’ LED will blink, and the buzzer will sound
continuously if alarms are enabled. Also, if the RS-232 Safe Mode is enabled, an auto-alarm message will be
sent to an attached computer.
Pressing any key will stop the buzzer and clear the alarm. When the problem causing the pump motor to stall
has been corrected, the Pumping Program can be resumed from any start trigger source: ‘Start’/’Stop’ key,
TTL input, or RS-232 command.

Program will automatically start operating when power is reconnected to the pump. Pressing any key on the
keypad while powering up the pump will stop the Pumping Program from starting.

) CAUTION: The Pumping Program will start operating from the beginning of the Pumping Program
(Phase 1), regardless of what part of the Pumping Program was operating when the power was disrupted.
When the NE-1000 syringe pump is used as a component in an automated infusion/withdrawal dispensing
system, a Pumping Program can be designed to automatically synchronize the pusher block at the start of the
Pumping Program. This would be accomplished using attached sensors that send signals to the Pumping
Program.

8.2 Low Noise Mode

n Setting: ‘0’ = Disabled, ‘1’ = Enabled.
A side effect of the NE-1000’s high precision micro-stepped motor driver is a high frequency resonance sound
at very low pumping speeds. This mode minimizes this sound by reducing the micro-stepping, increasing
pulsations.

8.3 Audible Alarm Enable

n Setting: ‘0’ = Disabled, ‘1’ = Enabled.
When alarms are enabled, a steady buzzer alarm will sound during alarm conditions, such as when the motor
stalls: Pressing any key will stop the alarm.

8.5 TTL I/O Directional Control Input Configuration

aa Configures how the TTL input ‘Pumping Direction’ (pin 3) will control the pumping direction.
(See sec. 11.1, TTL I/O Operational Controls). The 2 letter configuration parameter to the right of the colon
(:) is defined as follows:
Setting Name Function
rE Reciprocating Pumps Falling edge: Infuse; Rising edge: Withdraw
dU Dual Pump Falling edge: Withdraw; Rising edge: Infuse

The setting names are relevant to a 2 pump system, whereby the ‘Directional Control Input’ TTL pin is
attached to the second pump’s ‘Pumping Direction Output’ TTL pin.
In addition, “Directional Control Input” will affect how the “Sticky Direction” function operates. See “ Sticky
Direction”, sec: 6.8.1

8.6 Pump Motor Operating TTL Output Configuration

n Configures the functionality of the 'Pump Motor Operating' TTL output pin (TTL pin 7).
Settings: 0: Sets the output to logic high only when the motor is operating (pumping).
Sets the output to logic low when the motor is not operating or when the Pumping Program is
executing a pause timer or is stopped
1: Sets the output to logic high when the motor is operating (pumping) or when the Pumping
Program is executing a pause timer. Also alters operation of Alternating Communications Mode.
Set the output to logic low when the Pumping Program is stopped

8.7 Keypad Lockout

n Setting: '0' = Disabled, '1' = Enabled.
*** The "Lockout Disable Key" needs to be inserted into the TTL I/O connector to display this setting***
When enabled, the "Lockout Disable Key" needs to be inserted in the TTL I/O connector to change any of the
pump's settings. When the key is removed, the user can only start or stop the pump and review current
settings. Settings can still be changed from RS-232. When the user attempts to change a setting, the message

will be displayed.
Auto-Run Mode: When used in conjuction with the Sub-Program Select programming function as Phase 1, the
pump will enter Auto-Run Mode. In this mode, on power up, the Pumping Program will immediately begin to
execute and the user would be prompted to enter a Sub-Program number.
The "Lockout Disable Key" connects the "Program Input", TTL connector pin 6, to Ground, pin 9. The
"Lockout Disable Key" is available as an accessory item.
Lockout can also be disabled by performing a system reset, see sec. 6.13.2, "Reset Pumping Program."

8.8 Keypad and Notification Beep Enable

n Setting: ‘0’ = Disabled, ‘1’ = Enabled.
When enabled, a beep will sound as follows:
Condition Buzzer Action
Pumping Program ended Continuous beeping
Pumping Program paused for start trigger Continuous beeping
A keypad button is pressed Single beep

8.9 RS-232 Pump Network Configuration

nn The pump can be configured to communicate either with a
computer or another pump. Communications with a computer (Address Mode) is the default setting and will
be indicated by the [Ad:nn] display.
When in the default Address Mode, up to 100 pumps can be attached to a computer in a single pump network.
The network address is defined by the 2 digits to the right of the colon (:). The valid range of addresses is
from ‘00’ to ‘99’. If only one pump is attached to the computer, set the network address to 0, [Ad:00] (factory
default).
After the network address is displayed, the baud rate is displayed. Each pump in the pump network and the
computer must have the same baud rate setting. Any arrow key can be used to scroll through the selection of
baud rates. The supported baud rates are: 300, 1200, 2400, 9600, and 19200 (displayed as [1920]).

Alternating Pumps. Starts second pump when current pumping
program stops. Modified by TTL RUN.1 and OUT.0 setting.

Note: Communications with a computer requires the accessory cable: CBL-PC-PUMP-7.

Dual pump modes requires the accessory cable: CBL-DUAL-3

In Reciprocating or Dual Pumps Modes, the secondary pump must be left in its default communications setting
of Address Mode, Address 0, and 19,200 baud rate. See the documentation with CBL-DUAL-3 cable for more
detailed information.

9. Pumping Program
A Pumping Program is simply a pre-defined sequence of actions, or functions, which guarantees consistent and
precise operation of the pump, automatically, and with or without any user intervention. A Pumping Program
can be as simple as continuous pumping at a fixed infusion rate. Or a Pumping Programs could consist of a
pumping rate and direction of pumping for a specified volume, then switch to another pumping rate. Also a
Program can interact with external devices through the TTL I/O connector, make decisions, or stop pumping
for a period of time.
Programs are broken into individual operations called Phases. Each Phase consists of a function that can be a
control function or pumping function. A pumping function, such as ‘RATE’, consists of a pumping rate,
optional “Volume to be Dispensed”, and the pumping direction.
Complex dispensing systems can be designed, involving multiple liquids, each dispensed from a different
pump, plus other equipment and sensors. Pumping Programs can be designed for each pump which enables
multiple pumps to synchronize with each other, and the other equipment and sensors, using a cable connected
to the TTL I/O connectors of each pump.
When the Pumping Program is started, either from the keypad, TTL I/O connector, or from RS-232, the
Pumping Program will begin with Phase 1 of the Program. After the completion of each Phase, the pump will
immediately start the next consecutive Phase. This linear sequence of Phases can be altered by certain
functions that direct the Pumping Program to continue operation with a different Phase number. Some
functions can change the order of operation conditionally based on external events.

9.1 How to Enter Pumping Programs

A Pumping Program can be entered directly from the pump’s keypad, or uploaded from a computer using
PUMPTERM or SyringePumpPro software. A Pumping Program can be stored in a text file and edited with
any word processor, which facilitates development and maintenance of the program. A Pumping Program
generator spreadsheet is available to assist in developing a Pumping Program and to create the text file for
uploading to a pump.
Start by organizing your pumping requirements into specific actions and conditions that can then be
programmed into Phases. For more advance programming methods, common groups of Phases can be
grouped together and repeated multiple times using looping and jump functions.
The current values of the pumping rate, optional “Volume to be Dispensed”, and pumping direction, all refer to
the currently selected Phase. To display or change the currently selected Phase, enter “Program Entry Mode”
by pressing and holding the ‘Rate’/’Program Phase #’ key until the current Phase number is displayed. The

display will show , where ‘01’ refers to Phase 1. The pump will now be in “Program Entry

18

www.k echnology.it
NE-1010/510/511 High Pressure New Era Pump Systems™

Mode”. If the current Phase is not 1, press and hold the ‘Rate’/’Program Phase #’ key until the display is as
shown. The pump will now be in Phase 1.
When in “Program Entry Mode”, with the display showing the Program Phase number, pressing the
‘Volume’/’Program Function’ key will display the current “Program Function” for this Phase. If the current
function is ‘RATE’, then a pumping infusion or withdrawal can be setup for this Phase.
To change the “Program Function” selected, use the arrow keys to scroll through the functions until the
required function is displayed. If the function has an associated parameter, enter the parameter after the
function has been stored.
Momentarily pressing the ‘Volume’/’Program Function’ key again will exit “Program Entry Mode” and
display the “Volume to be Dispensed.” The pumping rate data, which includes the pumping rate, “Volume to
be Dispensed” and pumping direction, can now be setup as previously described.
When finished setting up the pumping rate data for the current Phase, enter “Program Entry Mode” again to
select the next Program Phase. Press and hold the ‘Rate’/’Program Phase #’ key until the Phase number is
displayed. Then use the arrow keys to set the Phase number to the next Phase to be setup. Pressing the right-
most arrow once will set the Phase to Phase 2. Now all pumping data will refer to Phase 2. The second Phase
can now be setup as described above for Phase 1.
Continue selecting Phase numbers and entering the infusion or control setup for each Phase of the Pumping
Program. The entire Pumping Program will be stored in non-volatile memory.
Use the ‘STOP’ function to stop the pump and end the Pumping Program. If the Pumping Program does not
operate the pump continuously, the last Phase of the Pumping Program must be a ‘STOP’ function (unless the
last Phase number is the maximum Phase number).
When the Pumping Program is started, with the ‘Start / Stop’ key, TTL I/O input, or RS-232 command, the
Pumping Program will begin operating from Phase 1.
Very complex dispensing Programs can be created with the Program functions available. Section 9.3 contains
a detailed description of all the functions.
9.1.1 Pumping Program Phase Number
To set the current Program Phase number, enter “Program Entry Mode” and display the current Program Phase
number.
Using the right-most 2 arrow keys, change the selected Program Phase number. The displayed Program Phase
number now becomes the currently selected Program Phase number. All function and pumping rate data will
now refer to the currently selected Program Phase number.
If the maximum Program Phase number, 41, is exceeded while changing the Phase number, the displayed
Phase number will automatically be set to the maximum Program Phase number.

9.2 Pumping Program Edit Functions

When developing or updating a large Pumping Program, occasionally one or more Program Phases needs to be
added or removed from the Pumping Program. Having to re-enter the entire Program could certainly be a
tedious task.
Two Program entry functions are available to simplify the Program development process. These are the
‘Insert’ and ‘Delete’ functions. They allow a Program Phase to be removed from any point in the Pumping
Program or a Phase to be inserted at any point.
To access these functions, enter “Program Entry Mode” to display the Program Phase number [PH:nn]. Select
the Program Phase number that is to be deleted or the Phase number where a new Phase is to be inserted in the
Pumping Program.
For example, if a Phase is to be inserted between Phases 24 and 25, select Phase 25. The inserted Phase will
be at Phase 25, and all the Phases starting with the old Phase 25 will be shifted one Phase higher.
Using either of the 2 left-most arrow keys, under ‘PH’ in the display, select the editing function. The arrow
keys will scroll through the selection of editing functions:

19

www.k echnology.it
NE-1010/510/511 High Pressure New Era Pump Systems™

Editing Function Description

PH Phase select
In Insert Phase
dE Delete Phase
When the required editing function is displayed, press the ‘Rate’/’Program Phase #’ key before the 2 second
time out. After the time out, or with any other key press, the function will be canceled.
If ‘Insert’ or ‘Delete’ was selected, the Pumping Program will be edited. While the Program is being edited,
the display will show [BUSY].
If ‘Insert’ was selected, all Phases from the selected Phase to the maximum Phase will be moved to the next
higher Phase, with the original maximum Phase being deleted. The inserted Phase will default to a ‘RATE’
function, if it is the first Phase, or a ‘STOP’ function otherwise.
If ‘Delete’ was selected, the selected Phase will be removed, and all Phases higher than the selected Phase, up
to the maximum Phase, will be moved to the next lower Phase.
All Phases that reference the Phase number of another Phase, such as a ‘jump’ function or an ‘event’ function,
will be automatically updated. The referenced Phase numbers will be automatically adjusted to compensate
for the section of the Pumping Program that was shifted during the operation of the edit function.
Ultimately, the easiest method to maintain and develop Pumping Programs is to download the Pumping
Program to the pump from an attached computer. This would allow a single Pumping Program to be quickly
programmed into multiple pumps. The computer would only need to be attached during the download since
the Pumping Program is stored in the pump’s non-volatile memory.
Also, a Pumping Program can be uploaded to an attached computer, which could then store it and produce a
printout of the Pumping Program.

9.3 Program Function Descriptions

Î Each program function must be in a separate Program Phase Í
9.3.1 ‘rAtE’: Rate Function

Defines a pumping function with a fixed pumping rate. This function defines a pumping setup
consisting of the pumping rate, optional “Volume to be Dispensed”, and pumping direction. Use the ‘Rate’,
‘Volume’, and ‘Pumping Direction’ keys to set or review the pumping setup. For continuous pumping, set the
“Volume to be Dispensed” to 0.0 (off). The “Volume to be Delivered” is disabled when the display reads
[ off].
9.3.2 ‘FILL’: Fill Function

The Fill function reverses the pumping direction and withdraws or dispenses the volume
dispensed or withdrawn. After a series of arbitrary dispenses, the Fill Function uses the Volume Dispensed to
automatcally refill the syringe. The Volume Dispensed is cleared when the Fill Function begins.
The pumping rate can be set, as with the Rate Function.
Fill at the current dispense/withdraw rate: If the Fill function’s pumpng rate is set to 0.0, the previous
function’s pumping rate will be used for the Fill rate.

9.3.3 ‘InCr’: Increment Rate Function

The increment and decrement functions operate the same as the ‘RATE’ function, except that the
specified rate is added (‘INCR’) or subtracted (‘DECR’) from the current pumping rate. The current pumping
rate when the function is executed is the base pumping rate for the function. If no base pumping rate exists,
such as when executing a pause function or when the Pumping Program is first started, a Program error will
occur and the Program will stop.
The pumping rate units will be the same as the base pumping rate, and therefore cannot be set, nor are they
displayed, with the pumping rate increment or decrement value. As with the ‘RATE’ function, a “Volume to
be Dispensed” and pumping direction can be specified for the increment and decrement functions.

20

www.k echnology.it
NE-1010/510/511 High Pressure New Era Pump Systems™

When used within a Program loop, the pumping rate can be incremented or decremented in small step
intervals.
9.3.4 ‘DECr’: Decrement Rate Function

The decrement function subtracts the specified rate from the current pumping rate. For a full
description, see section 9.3.3, ‘InCr’: Increment Rate Function..
9.3.5 ‘StoP’: Stop Pumping Operation and End the Program

Stops the pumping operation and stops the Pumping Program. The Pumping Program will begin
at Phase 1 when started again. An implicit ‘Stop’ function is executed when the Program exceeds the
maximum Phase number during operation.
If alarms are enabled, the buzzer will beep continuously when the Pumping Program stops.
9.3.6 ‘JP:nn’: Jump to Phase

nn The ‘Jump’ function alters the consecutive operation of Program Phases. When executed, the
Pumping Program will continue operation with Phase ‘nn’.
9.3.7 'Pr:In': Sub-Program Selection Input
The Pumping Program can be broken into sub-programs which can be selected by the user.
Auto-Run Production Mode: When Phase 1 is set to Program Selection Input, and Lockout Mode is selected,
the pump will enter Auto-Run Mode. When the pump is powered on, it will immediately begin executing the
Pumping Program. The user will immediately be prompted to enter a sub-program number. This permits a set
of production dispenses to be programmed into the pump. The user then would only be able to select from one
of these production dispenses and not make any changes.
Foot Switch Trigger Feature: If the Pumping Program was Paused, and the Paused Phase was a continuous
pumping Rate function, then starting the pump with a foot switch will cancel the Pause and restart the
Pumping Program Phase 1 causing the current program selection to be re-executed.

When the Program Selection Input function is executed, the Pumping Program pauses and

displays: nn , where 'nn' is the Program Selection.

Using the right 2 arrow keys, under 'nn', the user enters the Label of the required Pumping Program. The
Pumping Program Label is defined by any number from 0 to 99. When the 'Start' key is pressed, the Pumping
Program continues execution at the Program Phase with the selected Pumping Program Selection Label. Also,
the accumulated infusion and withdrawal dispensed volumes are set to zero.
The pump searches for the selected Pumping Program Selection Label starting with the current Phase and
continuing to the end of the Pumping Program memory, then from Phase 1 until the current Phase is reached

again. If the selected label is not found, the 'out of range' error message is displayed. Pressing
any key returns the display to the Program Selection Input display.
If more than one Phase is defined with the same label, then execution continues with the first matching label
encountered. The last selected program label is stored in non-volatile memory and becomes the default label
the next time the current Program Phase is executed. More than one Program Selection Input function can be
defined and placed at any Program Phase needed. To cancel the Program Select Input and stop the Pumping
Program, turn the power to the pump off and on.
If alarms are enabled, the buzzer will beep continuously while waiting for the start trigger.

21

NE-1010/510/511 High Pressure New Era Pump Systems™

9.3.8 'Pr:nn': Sub-Program Start Label

The Sub-Program Start Label function defines the start of a Pumping Program sub-program that
can be selected by the user during Pump Program execution.
After selecting the function, change '00', if needed, to a unique Program Label, from 0 to 99. See sec: 9.3.7,
'Pr:In': Sub-Program Selection Input for a full description. Place a Sub-Program Start Label, with a unique
number for each Sub-Program, from 0 to 99, at the starting Phase of each sub-program section.
When the Pumping Program encounters a Sub-Program Start Label in normal execution, it will be interpreted
as “Jump to Phase 1” [JP:01], ending the sub-program, and, assuming Phase 1 is a Sub-Program Select
function, [Pr:In], the user will be immediately prompted to select a sub-program.

9.3.9 ‘LP:ST’: Define Starting Phase of Loop

Defines the start of a Program loop. For a full description of Program looping, see sec. 9.3.11,
‘LP:nn’: .
9.3.10 ‘LP:EN’: Define Continuous Loop End

Loops to the most recently executed, unpaired, ‘loop start’ Phase, or Phase 1 if none. This
function allows a section of the Program to be repeated continuously. For a full description of Program
looping, see sec. 9.3.11, ‘LP:nn’: .
9.3.11 ‘LP:nn’: Define Loop End and Loop Repetitions

nn Repeats execution of the defined loop ‘nn’ times.

Loop starts and loop ends are uniquely paired during looping. When an unpaired ‘loop end’ function is
executed, it is paired with the most recent unpaired ‘loop start’ function executed (‘LP:ST’). If no unpaired
‘loop start’ function exists, Phase 1 is used as an implied unpaired ‘loop start’. This pairing defines the loop
and the range of Phase numbers between the paired loop functions defines the scope of the loop.
When a ‘loop end’ function is executed, Program operation continues with the ‘loop start’ function paired with
the loop end function. There are 2 ‘loop end’ functions: Loop continuous (‘LP:EN’) and Loop for a preset
number of iterations (‘LP:nn’), indicated by ‘nn’. Each time a paired ‘loop end’ function is executed, an
iteration of the loop is complete. With the ‘LP:nn’ function, after ‘nn’ number of loop iterations, the defined
loop is complete and Program execution continues with the next Program Phase after the ‘loop end’ function.
The loop is then no longer defined or paired.
While executing Phases within the scope of a defined loop, another ‘loop start’ and ‘loop end’ can be paired
and become a defined loop within the scope of the first loop, which is referred to as the outer loop. The new
loop being referred to as the inner loop. The pairing of a loop within a paired loop is referred to as nesting of
loops, with each loop being one nested layer for the duration of the loops pairing. Loops can be nested for a
total of 3 layers deep. Loops can only be nested within the scope of an outer loop.
9.3.12 'PS:nn': Pause Pumping
If ‘nn’ is non-zero, the Pumping Program will pause pumping (stops pumping) for ‘nn’ seconds. When

executed, the display will show nn , with ‘nn’ decrementing to indicate the number of seconds until
the next Program Phase is executed. After the pause interval, the next Program Phase will be executed.
To set a pause time in tenths of seconds, select the decimal point between the digits. To select the decimal
point, press and hold the right-most arrow key until the right-most digit scrolls to 9. After 9, the decimal point

between the 2 digits will toggle on and off . Release the key when the decimal point is displayed,
or cleared, as required. Now enter the required pause time from 0.1 to 9.9 seconds. While executing a pause
time set in tenths of seconds, the display will only show '01' seconds during the pause.
For pauses longer than the ‘99’ second maximum pause for this function, put the pause function within a
Program loop. A Program section with the following functions in consecutive Phases:
[LP:ST] [LP:ST] [PS:60] [LP:60] [LP:24],

22

www.k echnology.it
NE-1010/510/511 High Pressure New Era Pump Systems™

will pause the Pumping Program for 24 hours.

If ‘nn’ is ‘00’ then the Pumping Program pauses and waits for a start trigger to resume the Program. The

display will show when waiting for a start trigger.

After the start trigger, the Program will resume with the next Phase. The start trigger can be from any source,
the ‘Start’/’Stop’ key, the TTL I/O Operational Trigger, or from RS-232. Any other key input will stop and
reset the Pumping Program.
If alarms are enabled, the buzzer will beep continuously while waiting for the start trigger.
9.3.13 'IF:nn': Jump to Phase If External Trigger

nn The ‘IF’ function conditionally alters the Pumping Program’s execution based on an external
signal.
When executed, if the TTL I/O Program Input pin (pin 6) is low level, then the Pumping Program continues
operation with Phase number ‘nn’. Otherwise, the Pumping Program continues operation with the next Phase.
9.3.14 'Et:nn': Setup Event Trigger Jump Phase

nn The ‘Event’ function sets a background event trap that is triggered by an external signal.
This one time background trap, or interrupt, stays set during the Pumping Program’s entire execution until it is
triggered, redefined, or reset. This function has no other effect on the operation of the pump until it is
triggered.
The event is triggered with either:
1) A falling edge (high to low TTL transition) on the TTL ‘Event Trigger’ input (pin 4).
2) A low level on the 'Event Trigger' input pin of at least 200 ms at the time the function is executed.
3) The RS-232 ‘RUN E’ command.
When triggered, the current operation of the pump and the Pumping Program is interrupted, and the Pumping
Program immediately continues operation (jumps to) with Phase number ‘nn’.
After being triggered, the event trigger is reset. If an event trigger function is executed (either 'Et' or ES'
function) while another event trap is still set, the new event trigger will replace the previous event trap. Only
one event can be defined at any time.
9.3.15 'ES:nn': Setup Event Square Wave Trigger Jump Phase
nn The 'Event Square Wave' function operates the same as the 'ET' 'Event' function, with the
exception of the triggering conditions.
The event is triggered with either:
1) The rising or falling edge of the TTL ‘Event Trigger’ input (pin 4).
2) The RS-232 ‘RUN E’ command.
Therefore, a square wave function on the inupt pin can be used to toggle the pump between 2 sections of a
Pumping Program. An example of this would be a Pumping Program that switched between a slow and fast
pumping rate, controlled by a square wave input.

9.3.16 'Et:rS': Event Reset

’Event Reset’ cancels a previously set event trap by either the 'ES' or 'ET' function.
9.3.17 ‘CLr.d’: Clear Total Volume Dispensed

Sets the total volume dispensed to 0. Both infusion and withdraw volumes are reset.

23

NE-1010/510/511 High Pressure New Era Pump Systems™

9.3.18 ‘tr:aa’: Override Operational Trigger Configuration

aa
Sets the Operational Trigger (pin 2) to mode ‘aa’, overriding the default setup Operational
Trigger Configuration. See Sec. 8.4, ‘TTL I/O Operational Trigger Default Configuration’, for the settings for
parameter ‘aa’. The default setting for the Operational Trigger is always used to start the Pumping Program.
9.3.18.1 Trigger Event-Trap

‘Button Trigger Event Trap’ redirects a press of the ‘Stop’ key to the background event trap.

‘Trigger Event Trap’ redirects a stop pump Operational Trigger to the background event trap.

Instead of stopping the pump, an event defined by the ‘Event’ or ‘Event Square Wave’ function will be
triggered, causing the Pumping Program to continue execution at the Phase number defined in the Event
function.

If an Event Trap has not been defined, then the Pumping Program continues execution at the next program
phase. This is useful if the pump is executing a continuous infusion Phase. The pump can continue to infuse
until a foot switch is pressed. The pumping program can then jump to a different Phase, such as a withdraw
Phase, then stop the pump.

The Trigger Event Trap is a one-time function. After triggering an Event Trap, the Trigger Event Trap is
cleared. The Trigger Event function will not affect the current trigger configuration.
9.3.19 'OUt.n': Set TTL Output Pin

n
Set ‘Program Output’ TTL I/O output (pin 5) to level ‘n’. If ‘n’ = 0, the output pin will be set
low. If ‘n’ = 1, the output pin will be set high.
9.3.20 'bEEP': Beep

Sounds a short beep.

A more complex dispensing example, this Program contains different pumping requirements, including
dispenses with multiple pumping rates. The first set of 3 dispenses drops down to a lower pumping rate during
the dispense. When each dispense is completed, the buzzer beeps to alert the operator, then the pump waits for
a start trigger before starting the next dispense.
The next set of 3 dispenses have a fixed time interval of 60 seconds between dispenses. After the last set of
dispenses, the syringe is refilled by the amount infused, 17.25 mL. Then the buzzer beeps, to alert the operator
to the start of the first set of dispenses. The process is then repeated.

Program Pressure high sensor

This example demonstrates a Pumping Program whose control depends on an external sensor. Assuming a
pressure sensor that is configured to detect a high pressure point and a low pressure point, the Pumping
Program individually selects whether it will react to the high or low pressure point.
The “Program Output” pin on the TTL I/O connector (pin 5) is used to select the high or low pressure point.
When low, the low pressure point is selected (PH:01), and when high, the high pressure point is selected
(PH:05). The Program begins by infusing continuously at 10.0 mL/hr (PH:02), while a background trap is set
for the low pressure point (PH:03). To create a delay when the pressure sensor is switched from high pressure
to low pressure when the “Program Output” pin is set, a small volume is pumped (PH:02, 06) before the
background traps are set.
When the low pressure trap is triggered, the pump sets the high pressure trap (PH:07) and begins to increment
the flow rate. The flow rate is incremented in 1.0 mL/hr steps with every 0.25 mL dispensed (PH:08-10). If
the high pressure trap hasn’t as yet been triggered, the flow rate will max out at 25.0 mL/hr while waiting for
the high pressure trap (PH:11). When the high pressure point is reached, the pump immediately will drop
down to 10.0 mL/hr (PH:02), and once again wait for the low pressure point.

The following is an automated dispensing Program for a NE-1000 syringe pump equipped with a ‘Syringe
Filled Sensor’ attached to the TTL I/O connector, and a valve system to refill the syringe from a reservoir. It is
also assumed that the ‘Power Failure’ mode is enabled.
After a power fail restart, the pusher block is in an unknown position, making it impossible for an automated
dispensing system to regain synchronization. With the Syringe Filled Sensor, the following Pumping Program
will automatically synchronize the dispensing system, and then continue with the normal dispense.
The first 2 Phases set an event trap for the Syringe Filled Sensor and refills the syringe until the sensor is
triggered. When the sensor triggers the event, the pump’s pusher block will be synchronized with the Pumping
Program. It is assumed that the sensor is positioned to refill the syringe with 60 mL. A withdraw volume of
61 mL is set as a safety feature.
After the syringe is refilled, one 5 mL dispense is made every 5 hours. After 12 dispenses, the syringe is
refilled using the sensor again.

9.4.7 Example 7: Sub-Programs

This example shows some of the flexibilities provided by the Program Selection functions. The Pumping
Program starts by refilling the syringe with 50 mL at a fast pumping rate (Phase 1), then the Pumping Program
pauses for user sub-program selection (Phase 3). Then performs 5 dispenses of 10 mL at the selected rates,
then refills the syringe again and pauses for the next user sub-program selection.
The user is given the option of choosing one of three defined sub-programs.
1: Dispense 10 mL at 100 mL/hr (Phase 4)
2: Dispense 10 mL at 500 mL/hr (Phase 7)
3: Dispense 10 mL at 750 mL/hr (Phase 10)
After selecting the sub-program and pressing 'Start', the Pumping program continues execution at the selected
sub-program. After the 10 mL dispense, each sub-program jumps or continues with the loop counter function
(Phase 12). The first 4 loops continue Program Execution with the next user sub-program selection. After the
5th loop, the program continues with Phase 13, which jumps back to the syringe refill function and starts the
whole program over.

This example demonstrates a complex interaction with external equipment, such as synchronizing with another
syringe pump. The Program includes a variety of interactions with external equipment, which demonstrates
the various control possibilities of the NE-1000.
The Pumping Program begins by canceling any previous event traps (PH:01) and raising the ‘Program Output’
TTL line (PH:02). After 5.0 mL has been dispensed at 800 mL/hr (PH:03), the ‘Program Output’ TTL line is
lowered (PH:04), sending a synchronization signal to another device.
The pump then continues to pump at 800 mL/hr (PH:06) until a synchronization signal is received at the
‘Event Trigger’ TTL input, causing the Program to jump to Phase 7 (PH:05).
The pump then withdraws 0.25 mL (PH:07), pauses for 1 second (PH:08), then repeats this process if the
Program Input TTL line is low (PH:09), otherwise it continues with the next Phase.
Next, the pump pauses for 10 seconds (PH:10). Then it pauses again for the lesser of another 10 seconds
(PH:12) or until an Event Trigger occurs (PH:11). The Program then restarts (PH:13).

10. RS-232 Communications

The NE-1000 Syringe Pump can communicate with any computer or device with an RS-232
communications port. The following assumes that the default Address Communications Mode is
set.

10.1 Connection and Networking

On the rear of the pump are 2 square RJ-11 (“phone jack” style) sockets.
Connect the RS-232 cable into the socket labeled “To Computer”. Connect the other end to the serial port on
the computer, or other control device. Turn power off to the pump and the computer before connecting cables.
If the pump is part of a pump network, connect a pump network cable between the socket labeled “To
Network”, on the first pump, and the socket labeled “To Computer” on the next pump in the network. Repeat
for each pump in the network, connecting the “To Network” socket of one pump to the “To Computer” socket
32

www.k echnology.it
NE-1010/510/511 High Pressure New Era Pump Systems™

on the next pump in the network. Up to 100 pumps can be networked together with a computer. See section
11, Logic Interface: TTL Input and Output, for a diagram of the rear of the pump. When communicating with
a pump in a multi-pump network, each preceding pump in the network must be powered on.
Each pump in the network needs a unique network address to identify the pump to the computer. Network
addresses are from 00 to 99. If the network consists of only 1 pump, set the pump’s address to 0. Also, each
pump needs to be set to the same baud rate as the computer. Use the ‘Setup’ function on the keypad to set the
network address and the baud rate. See section 6.12, ‘Setup’ . The '*ADR' command can also be used to set
the network address.
The supported baud rates are 300, 1200, 2400, 9600, and 19200. The trade-off on baud rates is
communications speed versus noise immunity. For most environments, 19200 would be acceptable. But in
environments that are electrically noisy and/or over long cables, the communications signal may degrade or be
disrupted, causing communications errors. In these situations, a lower baud rate may improve the reliability of
the communications.

10.2 RS-232 Protocol:

When the pump is used in a multi-pump network configuration, precede each command with a pump address.
Pumps will ignore all commands that do not have their defined network address. If the network address is not
specified in the command, the address will default to 0.
After a command is sent to the pump, the pump will not accept any further communications until the current
command has been processed. Completion of the command processing is indicated when the first byte of the
response packet is transmitted. While the user is changing data or configurations from the keypad, command
processing is delayed.
A triangle appears in the upper left corner of the LCD display after the pump has received valid
communications. This triangle remains on the display until the pump is powered off or until ‘Setup
Configuration’ is entered.
Communications to and from the pump uses the following data frame:
Supported RS-232 Data Frames
Baud rates: 19200, 9600, 2400, 1200, or 300
Frame: 10 bit data frame (8N1):
Start bit: 1
Data bits: 8
Stop bits: 1
Parity: None
Every command received by a pump in the network is acknowledged by the pump with a response packet that
includes a status character indicating the current operational state of the pump.
Two packet protocols are supported, Basic and Safe. The enabled communications protocol is stored in non-
volatile memory, and therefore will be in effect at power up. Safe Mode provides a safer communications
protocol than Basic Mode. Safe Mode detects corrupted data and loss of communication, as well as
automatically transmitting status packets when an alarm occurs.
Considering that the 19200 baud rate communicates at 52 μs per bit, a small glitch on the RS-232 cable,
flipping a single bit, can convert a transmitted infusion rate of 100 mL/hr into 900 mL/hr, the need for the Safe
Mode in a production environment is evident. However, Basic Mode is excellent for simplifying early
development of a control program.
While in the Basic Mode, the pump will accept either communications protocol, Basic or Safe, although the
response packet will be in the current communications mode. This allows a computer’s communication’s
driver to be designed with just one mode. A Safe Mode communications driver can send a ‘SAF’ command to
the pump in the Safe Mode protocol while the pump is in Basic Mode. The response to the ‘SAF’ command,
enabling Safe Mode, will then be in the Safe Mode protocol.

Command syntax (to pump):
<basic command protocol> => <command data> <CR>
Response syntax (from pump):
<basic response protocol> => <STX> <response data> <ETX>
In the “Basic” communications mode, a master-slave protocol is used, whereby the pump will only transmit in
response to a received command.
When the pump receives the <basic command protocol>, <command data> will automatically be stripped of
all space and control characters, and all text will be converted to upper case. This simplifies communications
with the pump when commands are being manually typed in from a generic terminal emulator.
To return the pump to Basic mode when in the Safe mode, send the following packet to the pump:
(0x2) ( 0x8) SAF0 (0x55) (0x43) (0x3)
10.2.3 RS-232 Protocol: Safe Mode

Response syntax (from pump):
<safe response protocol> => <STX> <length> <response data> <CRC 16> <ETX>
Safe mode uses a more structured protocol including detection of corrupted communications, communications
time outs, and auto-alarm responses. Safe mode is enabled using the ‘SAF’ command whose parameter setting
is stored in the non-volatile memory.

34

www.k echnology.it
NE-1010/510/511 High Pressure New Era Pump Systems™

Safe mode uses a modified master-slave protocol, whereby the pump transmits in response to a received
command. But, the pump also automatically transmits a status packet when an alarm condition occurs.
Corrupted communications is detected using the 16 bit CCITT CRC algorithm computed over <transmitted
data>. Packets transmitted and received include the CRC within the packets.
The parameter sent with the “SAF” command is the communications time out. This time out, in seconds, is the
time between the reception by the pump of consecutive valid communications packets. Each time a valid
communications packet is received, the time out is reset. If the time out elapses, a pump alarm will occur,

stopping the pump and the Pumping Program. The pump will display , and the buzzer will sound,
if alarms are enabled, alerting the user. The communications time out timer will not restart until the next
reception of a valid packet.
In addition, there is a 0.5 second packet inter-byte time out. While receiving a communications packet, and
before its complete reception, if a delay of 0.5 seconds occurs between bytes, the incomplete packet will be
discarded.
With the Auto-Alarm feature, whenever a pump alarm occurs, such as a pump stall, a response packet with the
alarm status information will automatically be transmitted.
Until the Safe Mode is disabled, each time power is applied to the pump, the pump defaults to the Safe mode
of communications, but the communications time out timer will not be enabled until the first reception of a
valid packet.
Although the communications time out timer is not enabled, the Auto-Alarm feature will be enabled.
Therefore, the pump will be in an Auto-Alarm only communications mode.
When power is applied to the pump, or if the system should reset, a system reset alarm occurs. The Auto-
Alarm feature, therefore, alerts the host computer that a pump reset has occurred.
Also, when the user changes the baud rate, the communications time out timer is disabled until the next valid
communications packet.

10.2.5 Network Command Burst

The Network Command Burst feature is only applicable when communicating to a network of pumps.
This special feature allows commands to be sent to a network of pumps simultaneously. For example,
changing the pumping rates simultaneously on a network of pumps.
Note: Since this special feature violates the general communications protocol of one command-one response,
all of the pumps will be responding simultaneously, and therefore the communications response to a Network
Command Burst will be gibberish and should be ignored.
Command Format
Command Burst => <n> <command> *
Network Command Burst => < Command Burst > [Network Command Burst]
Where <n> indicates the address of the pump that is to execute <command>. Maximum address is 9.
n => {0 ... 9}

Example: Simultaneously change the pumping rates of 3 pumps on a pump network as follows:
Pump 0: 100 mL/hr
Pump 1: 250 mL/hr
Pump 2: 375 mL/hr

Assuming that the current pumping rate units of all 3 pumps are currently mL/hr, send the following
command, followed by a carriage return <CR>, (spaces are optional):
0 rat 100 * 1 rat 250 * 2 rat 375 *

10.3 Command Errors and Alarms

If a command received by the pump is not recognized or the data is invalid, an error message will be in the
<data> field of the response packet following the <prompt> field. The following are the error responses:
<command error> => ? <error>
<error> =>
λ Command is not recognized (‘?’ only)
NA Command is not currently applicable
OOR Command data is out of range
COM Invalid communications packet received
IGN Command ignored due to a simultaneous new Phase start
When an alarm occurs, the alarm must be acknowledged before any data is changed or the pump is started.
Alarms are acknowledged by the user clearing the alarm message on the keypad, or the alarm status being sent
in response to any valid RS-232 command. An alarm message sent automatically in the Safe Mode will not
clear the alarm condition. This is to verify that the alarm message was sent to a receptive host, such as after a
power failure when both the computer and the pump were reset. In this case, the pump will most likely send
its reset alarm message before the computer has finished booting.

10.4 RS-232 Command Set

All data changed from RS-232 is stored in the non-volatile memory, except for changes to the pumping rate
while pumping. All “Program Phase Data” refers to the currently selected Program Phase. Use the Phase
select command (‘PHN’) to query or select the current Phase. A Phase consists of the pumping rate, ‘Volume
to be Dispensed’, and the pumping direction.
A packet without a command is interpreted as a status query. The addressed pump responds with a status only
response packet.
Except where noted, a command without any parameters is a query command. The response packet data will
include the requested data. In general, the query response data will be in the same format as the parameters for
setting the command. For example, the query diameter command ‘DIA’ will respond with ‘<float>‘ as the
response ‘<data>‘.
Otherwise, the command is a set command. If the data was set, a status only response packet will be sent. If
the data was not set, the response packet will include an error (<command error>) message indicating why the
data was not set.

‘DECR’ functions, these two responses are not the same.
RAT C <float> [ <rate units> ]
Allows the Pumping Program to continue after the pumping rate is changed. The RAT C command
will not clear a Paused Pumping state after the rate is changed when the Pumping Program is paused.
Normally, the Pumping Program would re-start from Phase 1 after the rate is changed while paused.
RAT I <float> [ <rate units> ]
Changes the pumping rate only if the pump is infusing. If the pumping direction is set to withdraw,
the rate change will be ignored.
VOLUME TO BE DISPENSED AND SET VOLUME UNITS
VOL [ <float> | <volume units>]
Set/query volume to be dispensed: <float>
Applicable only with “Rate Data Functions”. Can only be set when the Pumping Program is not
operating. The volume units are set according to the current syringe diameter setting. Do not send
the volume units when setting the volume.
Example: VOL 12.45 Sets the current phase “Volume to be Dispensed” to 12.45.
Set volume units: <volume units>
Overrides the default volume units set when the syringe diameter is set.
Example: VOL UL Sets all volume units to μL.
Query response:
<float> <volume units>
PUMPING DIRECTION
DIR [ INF | WDR | REV | STK ]
Set/query pumping direction

INF = Infuse
WDR = Withdraw
REV = Reverse pumping direction
STK = “Sticky Direction” (See “Sticky Direction”, sec: .6.8.1)
Applicable with all Program Phase functions. Cannot be set when the Pumping Program is operating
and the “Volume to be Dispensed” is non-zero.
The pumping direction cannot be changed if an alarm condition exists.

10.5 Getting Started With RS-232

Before beginning to develop pump control software for a computer, first setup and experiment with the pump’s
communication. After attaching the pump to the computer, run a terminal emulation Program on the
computer. A generic terminal emulator, supplied as standard software with many computers, can be used to
communicate with the pump in the Basic communications mode.
New Era Pump Systems Inc. supplies a terminal emulator, for demonstration purposes only, which allows
more complex control of the pump. Also, this terminal emulator contains a “Pump Programming Language”
(PPL™), which allows Pumping Programs to be developed using symbolic text, modified, and stored in
computer files, then uploaded to the pump. In addition, a Pumping Program generator spreadsheet is available
to assist in developing a Pumping Program and to create the text file for uploading to a pump.
With a generic terminal emulator, setup the terminal emulator with the same baud rate as the pump and with an
8 bit data, no parity, and 1 stop bit (8N1) data frame. Set the communications port to the port that is attached
to the pump. Also enable local echo (half-duplex) and turn flow control off.
From the terminal emulator, you can interactively control the pump by typing in commands on your computer
and seeing the pump’s responses on your screen. This will give you a feel for how the commands work in
addition to allowing you to quickly develop the control sequence that will eventually be coded into the
software being developed.
The final benefit of using a terminal emulator is the elimination of several variables if the control software
does not work properly. If the pump works correctly with the terminal emulator, then this verifies that the
hardware is working properly and will work with any software. Any communications problems can then be
narrowed down to the control software.
Note on USB: If an RS-232 port is not available on your PC, the pump may be operated through a USB to
RS-232 converter cable (available as an accessory, part #CBL-USB232). This cable attaches to the standard
RS-232 to PC cable (part #CBL-PC-PUMP-7). The PC will create a virtual RS-232 communications port that
communicates through the USB to RS-232 converter cable. The terminal emulator can communicate through
this virtual port.

Figure 2: Rear of Pump

On the rear of the pump is a DB-9 connector, below the ‘TTL-I/O’ label, which is used for TTL I/O. The logic
signals on this connector permit bi-directional control with external equipment.
Control input TTL logic levels must be held steady for a minimum of 100 ms to be recognized. To minimize
the possibility of false signals caused by glitches and ringing, which could be caused by the closure of
mechanical switches, TTL control inputs are firmware filtered. With a sampling period of 50 ms, glitches of
less than 100 ms are filtered out.
Edge detection requires the detection of a change in TTL levels. With a minimum of 100 ms to detect a level,
an edge requires a minimum of 200 ms to be detected. Since the next level change can be detected in 100 ms,
creating another edge, the maximum edge to edge frequency is 10 Hz.
Edge changes to the ‘Pumping Direction’ and ‘Operational Trigger’ inputs must occur at least 50 ms apart.
Falling edge refers to a logic high to logic low transition. Rising edge refers to a logic low to a logic high
transition. To guarantee recognition of logic levels, voltages on the input lines must be within the following
ranges:
TTL logic low (0): 0 to 1.5 V
logic high (1): 3.5 to 5.25 V
The Vcc and Ground pins, pins 1 and 9, are for logic reference only. To assure proper voltage levels, the
Ground pin should always be connected to the signal ground of a sensing or controlling device that is attached
to any other pin on the TTL I/O connector. The Vcc pin should not be used to source current. The TTL I/O
pins are defined as follows:

11.1 TTL I/O Operational Controls

While the user is changing settings or configuration from the keypad, external control by the ‘Pumping
Direction’ and ‘Operational Trigger’ inputs will be ignored. These controls will also be ignored if an alarm
condition exists.
Operational Trigger (Pin 2): The input signal on this pin controls the operation of the Pumping Program. Its
functionality is user configurable. Use the ‘TR:nn’ Setup Default Configuration to configure this input pin
(See Section 8.4, TTL I/O Operational Trigger Default Configuration).
Each option defines when the Operational Trigger input is activated. When activated, the trigger emulates the
‘Start/Stop’ key:
Foot Switch: Operates like the ‘Start/Stop’ key, whereby each falling edge (contact to ground) either starts
or stops/pauses the Pumping Program.
Foot Switch Hold: Falling edge starts the Pumping Program and the rising edge stops the Pumping Program.
With a foot switch, the Pumping Program will run while the foot switch was held down.
Foot Switch Reversed: Operates like the ‘Start/Stop’ key, whereby each rising edge either starts or
stops/pauses the Pumping Program.
Level Control: Falling edge stops/pauses the Pumping Program, Rising edge starts the Pumping Program.
This configuration can be used with a contact closure timer or in an automation setup,
allowing logic level control over the operation of the pump.
Start Only: Falling edge starts the Pumping Program. This configuration only allows the starting of the
Pumping Program. This would be useful, for example, with a laboratory animal trained to
press a lever. The animal can start the Pumping Program, but repeated presses would have
no effect until the Pumping Program permits it.
Start Only Reversed: Same as ‘Start Only’, but operates on the Rising edge to start the Pumping Program.

44

www.k echnology.it
NE-1010/510/511 High Pressure New Era Pump Systems™

Stop Only: Falling edge Stops the Pumping Program. This configuration only allows the
stopping/pausing of the Pumping Program. This would be useful, for example, with an end
of travel limit switch. Also, this switch can be used as a power on homing switch.

Stop Only Reversed: Same as ‘Stop Only’, but operates on the Rising edge to stop the Pumping Program.
Run on Low Level: Starts the pump whenever the level is low
Run on High Level: Starts the pump whenever the level is high
Stop on Low Level: Stop the pump whenever the level is low
Stop on High Level: Stop the pump whenever the level is high
Trigger off: Trigger control is disabled
Event Trap Trigger: Redirects a Stop Operational Trigger to the Event Trap.
Button Event Trigger: Redirects ‘Stop’ key to the Event Trap.
Pump Motor Operating (Pin 7): This output provides an external signal indicating when the pump motor is

operating. This pin is configured with the n setup command, or the "ROM" remote command.
When set to 0, the output is only at logic high when the motor is operating (pumping). When set to 1, the
output is logic high when the motor is operating or when the Pumping program is executing a pause timer.
Otherwise, the output is a logic low.
Pumping Direction Controls (Input: Pin 3; Output: Pin 8): Allows bi-directional control of the pumping
direction. The input pin, when activated, emulates the pumping direction key, changing the pumping direction.
This function, therefore, is only applicable where the pumping direction key would be applicable. The

function of the input pin is configured with the aa setup command, or the "DIN" remote command.
When the mode is set to reciprocating pumps ("rE" setup command), then if the current pumping direction is
withdraw, a falling edge sets the direction to infuse. If the current pumping direction is infuse, a rising edge
sets the direction to withdraw. Otherwise, this input pin has no effect.
When the mode is set to dual pumps ("dU" setup command), then if the current pumping direction is withdraw,
a rising edge sets the direction to infuse. If the current pumping direction is infuse, a falling edge sets the
direction to withdraw. Otherwise, this input pin has no effect.
Dual and reciprocating pumping systems are created using 2 pumps attached with the accessory cable CBL-
TTL-1.
The output pin provides an output signal to external devices indicating the direction of pumping. A logic low
indicates withdraw, and a logic high indicates infuse. For example, this pin can be used to control an external
valve, allowing the syringe to refill from a reservoir.

11.2 TTL I/O Control from the Pumping Program

Various Pumping Program functions can define how the pump reacts to levels on the TTL I/O connector or set
output levels. These are summarized in the following table:
Pumping Program TTL I/O Control Pin Pin Action
Function #
OUT.n Program Output 5 Set logic level output to ‘n’
EV:nn Event Trigger 4 Falling edge triggers a jump to Phase ‘nn’
ES:nn Event Square wave Trigger 4 Rising or falling edge triggers a jump to Phase 'nn'
IF:nn Program Input 6 Low level causes a jump to Phase ‘nn’
PS:00 Operational Trigger 2 Trigger activation resumes Program operation

11.3 TTL I/O Control from RS-232

The logic levels of pins 2, 3, 4, and 6 can be queried from an attached computer using the RS-232 ‘IN’
command.
The output logic level of pin 5 can be set with the RS-232 ‘OUT’ command.

12.3.4 Automation Cable: Special Communications Modes Control Cable

Part #: CBL-DUAL-3
Using two NE-1000 syringe pumps, this cable either creates an automated, continuous operation pumping
system, whereby one pump is refilling while the other is dispensing, or creates a dual pumping system, with
both pumps operating in the same direction. Plus other special communications modes.
This cable is attached to two NE-1000 syringe pumps via their RS-232 connectors. In this setup, with the
pumps configured for this operation, one pump acts as the Master controller. With the Master pump
programmed with a continuous infusion program, the other pump will always be pumping in the opposite
direction. With proper plumbing, this will create a continuous infusion system.
Alternatively, the pumps can be set to Dual Pump Mode, whereby the second pump will always follow the
program on the first pump, including starting, stopping, direction changes, and rate changes.
When either pump stops, for any reason, the other pump will stop.

12.4 Troubleshooting and Maintenance

Maintenance: Periodically, apply a small amount of all-purpose oil to the guide rods and grease to the drive
screw.
The mechanism should be kept clean to prevent impeded operation.
No other special maintenance or calibrations are needed
RS-232 Communications: If no RS-232 communications is possible or garbled responses are received from
the pump, check the following:
If the triangle appears in the upper left of the LCD display, then the pump is receiving valid communications.
The communications problem is probably with the receiving communication application or with the receive
line on the cable.
If the Basic communications mode is used, check if the pump is in Safe communications mode. See section
10.2, RS-232 Protocol:, for instructions on how to change the communications mode.
Verify the pump’s baud rate and network address. To set the RS-232 communications parameters, see section
6.12, ‘Setup’ .
Using a lower baud rate may also improve the reliability of the RS-232 communications.
Pusher block makes a snap or click sound when the pump is started: This is a normal condition. When
the pusher block is manually moved, the drive-nut may not have been fully engaged on the drive screw. The
sound heard is the drive-nut engaging on the drive screw.

must be the ‘Stop’ function. See section 9.1, How to Enter Pumping Programs, for instructions on changing
the Pumping Program.
Pump stops pumping after a period of time: A dispense target volume has been set. Verify that the
dispense target volume is set to 0.

This User Manual is an addendum to the standard NE-1000 User Manual and supersedes it.

1. Upgraded and New Programming Functions

Linear/Gradient Flow Rate Ramping

Linearly ramps up or down the flow rate. The pump will deliver a smooth, linearly increasing or decreasing, flow rate as defined by
the starting flow rate, ending flow rate, the total pumping time, and direction.

Phase ‘n+1’
Linear Function End Rate

R
a Linear Function Time
t Hour Minutes Seconds Tenths Seconds
e Phase ‘n’ Phase ‘n+1’

Phase ‘n’
Linear Function Start Rate
Time

The Linear Flow Rate function is specified by using two Linear Functions , in two consecutive Program Phases, defined by
four parameters:
1) Starting flow rate
2) Ending flow rate
3) Total time, expressed as "Hours : Minutes : Seconds : Tenth Seconds"
4) Pumping direction

The Linear Flow rate function is entered as follows, in two consecutive Pumping Program Phases:
Time is entered using the "Volume" key. The "min" minutes LED will be lit when time is displayed.
The units and pumping directions of the starting and ending flow rates must be the same.

Phase Function Rate/Units Time____________________________

Reciprocating Pumping for Auto-Refill Applications

The Reciprocating Pumping function will continuously reverse the pumping pumping direction at the end of the progammed dispense
volume. This function is setup the same as the Rate function. Set the rate, dispense volume and pumping direction.

After the set Target Volume is dispensed (or withdrawn), the pumping direction is reversed and the pump will withdraw (or infuse) the
set Target Volume. If the pumping rate is changed, the pump will continue pumping at the new rate when the pumping direction is
reversed.

With the addition of a dual check valve on the syringe, this function can be used to create an auto-refill system.

With the addition of a second pump, attached to the first pump with the control cable, CBL-DUAL-3, the dual pump plumbing kit,
P-DKIT, and the setting of the Reciprocating communications mode, a continuous infusion system can be setup. One pump will
always be infusing while the other pump is refilling.

RS-232 Remote Support:

Reciprocating function command: FUN REC

Base Pumping Rate and Volume

The Base function operates identical to the RATE function, except that the BASE Function's Rate and Volume will be used to override
the settings for subsequent RATE functions. This will allow the user to make modifications to the Rate and/or Volume settings in one
place, instead of having to make edits to each RATE function in a program individually.

RS-232 Remote Support:

Base Rate function command: FUN BAS

Increment and Decrement Functions

The INCR and DECR functions have been modified from previous versions to pump for a period of time instead of volume dispensed.

The dispense time is set using the "Volume" key and is expressed as "Minutes : Seconds". The "min" minutes LED will be lit when
time is displayed.

RS-232 Remote Support:

Increment function command: FUN INC
Decrement function command: FUN DEC
The time setting is sent to the pump or queried using the "TIM" remote function:
TIM [<nn> : <nn>]

nn Stall Event
“Stall Event” allows a Pumping Program to relieve the pressure on a syringe after a pump stall by jumping to a Phase that reverses the
pumping direction.

“Stall Event” creates a background event interrupt trap for a pump stall. If the pump stalls, the Pumping Program will continue
execution with the Program Phase ‘nn’ defined by the “Stall Event” function. After the pump stops, the “Stall” message is cleared and
the Pumping Program continues execution at the Stall Event Phase defined by parameter ‘nn’.

After a “Stall Event” trap is executed, the event trap is cleared. The “Stall Event” function needs to be set again to trap another stall.
“Stall Event” is independent from the standard “Event” and “Event Square” functions.

The “Event Reset” function will clear the “Stall Event” trap along with any other Event trap.

Program Sub-Routine Return

The “Return Function” is paired with Pumping Program Functions that cause the Pumping Program to branch to a different Program
Phase number. When executed, the "Return Function” causes the Pumping Program to continue Program execution at the interrupted
Phase (for Event Functions) or next Program Phase after the paired Program branch function. This changes the Program Branch
function into a Program Sub-routine call.

Program Branching functions affected are:

Functions that return to the next Phase:
JP:nn Jump unconditionally to Program Phase 'nn'
IF:nn Conditional jump if the Program Input pin is low

Event functions that return to the interrupted Phase:

ET:nn Set a background conditional jump on an event falling edge to Program Phase 'nn'
ES:nn Set a background conditional jump on any event edge to Program Phase 'nn'

These functions will operate normally, but when the next RET function is executed after the Program Branch function, program
operation will return to the Program Phase immediately following the Phase where the Pumping Program most recently branched
from, or the Program Phase that was interrupted for events:

IF:nn, JP:nn
After one of these functions cause a Program Phase Branch to Phase 'nn', a RET function will return the Program to the Phase
following the function that caused the most recent branch, thus converting these Pumping Program branch functions into program sub-
routine call functions.

ET:nn, ES:nn
These functions create a background Event trap. When the Event trap is triggered, the Pumping Program immediately jumps to
Program Phase 'nn'. A RET function will return to the Program Phase that was interrupted by the Event trap. NOTE: When the
Pumping Program returns to the interrupted Phase, the Program Phase starts over and not at the point that was interrupted. For
example, if the interrupted Phase specified a pumping volume, on return, the entire pumping volume will be dispensed, not just the
remainder of volume from the point of interruption.

The continuous pumping mode eliminates the problem of flow rate drop-off that is typical with
continuous syringe pump systems where one pump is refilling the syringe while the other infuses, and
then they switch directions.

In this system, the refilling pump refills at a faster rate than the infusing pump giving it time to prime the
syringe, then it pauses and waits for the infusing pump to empty.

Then, when the pumps switch directions, the refilled pump is primed and starts infusing at the set rate
immediately. Additionally, an overlap can be set, whereby the refilled syringe begins infusing before the
infusing pump is completely empty.

Reciprocating and Dual Modes

 ‡…‹’”‘…ƒ–‹‰‘†‡ —ƒŽ‘†‡
Opposite Pumping Directions Same Pumping Directions

Syringes: Each pump can have a different size syringe, but make sure that the pumping rates on
the Master pump are within range of the syringe used on the Secondary pump. If an out-of-range
pumping rate is sent to the Secondary pump, the rate will just be ignored by the Secondary pump
without affecting the operation of the Master pump.

Master Pump: Pumping rate and direction are only transmitted to the Secondary pump from the
Master pump while the Master pump is pumping. If the Master pump starts or stops, the
Secondary pump will start or stop. Linear Function pumping rates will not be transmitted.

Secondary Pump Controlled as Follows:

Reciprocating Mode: Master pump Rate and opposite pumping direction.
Dual Mode: Master pump Rate and current pumping direction.

Secondary Pump: Changes to the pumping rate and direction on the secondary pump will not be
transmitted to the Master pump. If the Secondary pump stops, the Master pump will also stop.

Pump Stall: If either pump stalls, then the other pump will also stop.

Synchronization between pumps: The secondary pump will lag approximately 30 milliseconds
behind the Master pump due to communications delay.

Reciprocating Pump Program

Below are examples of how to setup the pumps for reciprocating, continuous flow operation.
The Pump 1 program is the default program that is loaded as indicated in the "Default Program
Selection" section. Pump 1 is the Master pump which controls the Secondary pump's operation.
In Reciprocating mode, Pump 2 will pump continuously in the opposite direction of Pump 1, at
the same rate as Pump 1, and will change direction when Pump 1 changes direction.

Pump 2

Pump 1

Creates a semi-automated continuous infusion system using pre-loaded syringes.

The infusing pump will automatically start the alternate pump when the Pumping Program stops.
A Pause Function at the beginning of the alternate pump’s program will delay the start of
pumping.
The empty syringe can then be manually replaced during the infusion of the alternate pump.
Set both pumps to Alternating communications mode (“ALtr”) to create a continuous system.

‘X Version Firmware Only (Enhanced Features)

• Starts alternate pump after either a Pause function or when the program stops.
Set the TTL setup setting: RUN.0, (Default setting)
Alternate pump will start on execution of Pause function.
Set the TTL setup setting: RUN.1
Alternate pump will start when the Pumping Program has stopped.
• Overlap start of alternate pump.
Pumping Program Function: OUT.0
Immediately sends start to alternate pump when OUT.0 function is executed.
Allows the creation of an overlap between the infusing and the alternate pump to allow the
alternate pump to prime the syringe before the infusing pump stops.
Simultaneously start both pumps: If Phase 1 is set to function OUT.0, the alternate pump will
immediately start when the Master pump starts.
Overrides sending a start command to the alternate pump when the pump stops.
• Stop Alternating Mode
Set TTL Trigger Mode to “Off”. When trigger is set to “Off”, start command will not be sent to
alternate pump.
Within a Pumping Program, the trigger mode can be changed with the Trigger Off function:
(“tr:of”). This allows a Pumping Program to limit the number of times that the alternate pump
will execute its Pumping Program.

The continuous pumping mode eliminates the problem of flow rate drop-off that
is typical with continuous syringe pump systems, where one pump is refilling the
syringe, while the other infuses, and then they switch directions.
In this system, the refilling pump refills at a faster rate than the infusing pump, giving it time to
prime the syringe, then it pauses and waits for the infusing pump to empty.
Then, when the pumps switch directions, the refilled pump is primed and starts infusing at the set
rate immediately. Additionally, an overlap can be set, whereby the refilled syringe begins
infusing before the infusing pump is completely empty.
Requirements
• 2 Pumps from the NE-1000X series of syringe pumps. Pumps can be different models.
• 1 Dual pump cable, part #CBL-DUAL-3.
Set communications mode to Continuous Mode [Cont]
On the Master Pump only: In setup, when the network address is displayed [Ad:00], or other
address mode, press the left-most up arrow key to select [COnt].
Note: Do not change the default settings on the second pump: Address 0 [Ad:00] and 19,200
baud rate [1920]. If unsure, reset the secondary pump: While turning on power, hold the left-
most up arrow button. The display will show [rESt].
Set Pumping Parameters on the Master Pump
Set syringe diameter and pumping parameters on the Master pump. The syringe diameter and
pumping parameters are transmitted to the second pump when the Master pump starts. Both
syringes start empty, unless pre-filled syringes are specified.

Set any optional parameter to 0.000 (off) if not used, or set the function to STOP. Pumping rates
not set will default to the Infusion Pumping Rate.
Hardware Setup
Attach the cable, CBL-DUAL-3, to the “To Computer” connector on the back of both pumps.
Operational Sequence
- Both syringes start empty. Set Phase 4, pre-filled mode, to use pre-filled syringes.
- Start the Master pump: Both pumps start filling, unless pre-filled syringes are specified.
- When syringes are filled:
• Master pump starts infusing
• Second pump primes (if enabled), then pauses
- When the infusing pump reaches the overlap position, if enabled, or changes pumping direction,
the paused pump will start to infuse
- Sequence repeats:
• Refilling pump fills, primes, pausing and waits for the other pump.
• Infusing pump infuses to the overlap position or syringe empty, and then signals the
other pump to start infusing. When empty, changes direction and starts refilling

While Pumping
The pumping rate can be changed. The new pumping rate will be transmitted to the other pump,
into the corresponding pumping sequence.
Pressing the Stop key on either pump, will Pause the sequence on both pumps. Pressing the Start
key, on the Master pump, will continue the pumping sequence.
Power Failure Mode – Auto-Synchronization
After a power failure restart, or to start the infusion with partially filled syringes, limit switches
can be attached to the pump at the refill position of the syringes. Attach the limit switch wires
between the Trigger Input (pin 2) and Ground (pin 9) on the pump’s 9 pin TTL connector.
Then enable Power Failure Mode in the Master pump’s setup menu.
When the pumps start, they will begin by filling the syringes until either the syringe volume
target is reached or the limit switch is triggered. Power Failure Mode overrides pre-filled syringe
mode settings.

Notes and Error Messages

• The refill rate needs to be fast enough so that the syringe is refilled and primed before the
infusing pump has emptied.
• If the refilling pump is still pumping when the infusing pump empties, an error message
will be displayed and the pumps will stop.
• If the second pump is not the same model as the Master pump and the flow rates are not
compatible with the second pump, the Master pump will display an error message.
General Setup Error Messages:
[Er:02] Phase 1, syringe volume, is 0.
[Er:03] Phase 2, invalid overlapping volume setting.

5) Change RUN.0 (default value), if needed to change from single cycle mode.
Note: The secondary pump is set to the default communications settings of Address 0 and
19,200 baud rate.

Operation
When the Master pump is started, the Linear function will be expanded to a 3 or 5 Phase
Pumping program, depending on mode, representing the forward and inverse of the linear
function, then repeat. The second pump will then be programmed with the syringe diameter and
the inverse of the linear pumping program. The Second pump will start pumping when the
Master pump starts pumping.
With the starting and ending pumping rates reversed on the secondary pump, the sum of the flow
rates of the two pumps will be virtually constant.
Note: The linear function updates the pumping rate every 100 ms, resulting in a synchronization
error of up to 100 ms between the two pumps. This will cause a slight difference in the total
volumes dispensed between the two pumps.

NE-8000 Syringe Pump

Model NE-8000 High Pressure Syringe Pump
Features
- All Programming features of the NE-1000 syringe pump.
- Syringes size up to 140 mL. 200 mL partially filled (About 160 mL).
- Pumping force over 200 lbs.
Adjustable force limit: Force adjustment knob reduces the maximum force to reduce damage to syringes.
Limit Switches
- Two adjustable limit switches: One sets the infusion limit, one sets the withdrawal limit. To adjust the limit
switches, loosen the white thumbscrew, then slide the collar to the required position. Then re-tighten the
thumbscrew.
- When the pusher block reaches a limit switch, the pump will either: 1) Trigger a Program Event function;
2) Continue with the next Program Phase; 3) Stop the pump.
If a Program Event is set (Event Function), the Event trap will be triggered and the Pumping Program will
continue execution with the Program Phase set in the Event Function.
Otherwise, the Pumping Program will start the next Program Phase unless the next Program Phase pumps in the
same direction. This is a safety feature to prevent attempting to pump past the limit switch. The pump will
instead stop.
Limit switches can be used as a program volume target. Limit switches will override the volume target setting.
Additional Notes
- Does not have stall detection.
- Pusher block has a solid nut block. It is not releasable.
- To position the pusher block, use the purge function: Set the pumping direction with the direction key ‘ ’,

then press and hold the ‘Start/Stop’ key. The display will indicate and the pusher block will move at
top speed in the set direction. Release the ‘Start/Stop’ key to stop the pump.

Maintenance
 Periodic lubrication is required for proper operation. Failure of the nut block can occur if not properly
lubricated.
 Lead-screw: Grease
 Guide Rods: Oil
 Remove accumulation of dirt or debris

WARNING
Use extreme caution. The NE-8000 can deliver enough force to break syringes or any objects that get caught in
the mechanism. Broken syringes and associated plumbing can create dangerous projectiles that can cause bodily
harm. Keep fingers and loose clothing away from mechanism.
