Equipment Overview: Theory Of Operation

Theory Of Operation
The Monitor is a portable unit that receives input power from an external AC
source, or internal rechargeable battery.
When the Power button is pressed, the Main Board is brought out of a sleep
mode and turns on the power regulators. The power regulators provide
conditioned power from one of the two input power sources:

AC Mains

Internal battery

Once the Monitor is energized, a self-test is performed. The self-test

automatically tests the main functions of the Monitor. Failure of the self-test sets
the Monitor into a fail-safe mode with an audio alarm. Under normal operating
condition, the Monitor is ready to monitor the patient's vital signs using four
external attachments:

Temperature probe for either rectal or oral use

SpO2 sensor

ECG leads

Cuff

Interface with a central station or other device is accomplished through the 9pin host communication port or the 15-pin wireless communication port on the
back of the Monitor.

NELLCOR SpO2 and MASIMO SET SpO2

When the SpO2 sensor is attached to the SpO2 connector and to the patient, it
senses both the pulse rate and oxygen saturation. These analog signals are
routed to and analyzed by the SpO2 PWA. The results are digitized and sent to
the DAS Board, and DAS repacks and sends them to Main Board through the
opto couplers. The couplers provide for patient isolation as well as serial data
interface. The Main Board routes the data to the appropriate screen displays
and/or printer.
A reset signal to the SpO2 PWA is also provided for power up sequencing.

NELLCOR IS TRADEMARK OF NELLCOR PURITAN BENNETT INC.

MASIMO SET IS A TRADEMARK OF MASIMO CORPORATION. POSSESSION OR PURCHASE OF THIS DEVICE DOES NOT CONVEY ANY EXPRESS OR IMPLIED LICENSE TO USE THE DEVICE
WITH REPLACEMENT PARTS WHICH WOULD, ALONE, OR IN COMBINATION WITH THIS DEVICE, FALL WITHIN THE SCOPE OF ONE OR MORE OF THE PATENTS RELATING TO THE DEVICE.

Equipment Overview: Theory Of Operation

DINAMAP Blood Pressure and Pulse

When the cuff and hose are attached to the Monitor and Non-Invasive Blood
Pressure (NIBP) determination is initiated, the pump inflates the cuff. The
pressure transducers (PT1 and PT2) monitor pressure information. The
pneumatic manifold has two valves, which are used to deflate the cuff. Valve
control is through the Main Board. Determinations are made for the systolic BP,
diastolic BP, pulse rate, and Mean Arterial Pressure (MAP). The results are
displayed on the Monitor's front panel Liquid Crystal Display (LCD) screen.
If an over-inflation condition occurs, it is detected by PT2, resulting in assertion
of OVERPRESSURE. The OVERPRESSURE signal is routed to the PVM to release the
air pressure. The Main Board generates an alarm condition with the speaker
sounding and a message in the LCD.

Alaris Oral and Rectal TURBO TEMP Thermometry

The Monitor has one temperature channel for oral or rectal determinations.
When a temperature probe is attached to the temperature connector and to the
patient, TEMP input is routed to the DAS Board. This input represents the
temperature to be measured. The DAS Board converts the TEMP signal to a
digital signal and sends to Main Board. During the conversion, the Main Board
determines the patient temperature using either a predictive or monitor mode
algorithm depending on the user's setup. The patient temperature is distributed
as a digital signal to the LCD display or to the printer.
The Monitor has a probe check feature to determine if a probe is connected to
the Monitor and whether it is an oral or rectal probe.

ECG with Heart Rate and Respiration

The ECG parameter provides an electro-cardiographic waveform in 3-electrode
or 5-electrode configuration. The 3-electrode configuration derives a waveform
from Lead I, II, III and displays this waveform as the primary lead. The 5electrode configuration derives waveforms from Lead I, II, III, aVR, aVL, aVF, VA,
and displays this waveform as the primary lead. In 5-electrode configuration,
another waveform can be displayed as the secondary lead.
Breath rate is calculated by measuring the thoracic impedance between two
electrodes. As the patient breathes, the movement of the chest changes the
measured impedance to produce the respiration rate.
In the ECG menu for the monitor, the pacer detection option enables/disables
the pacemaker detection algorithm. It must be used whenever the monitored
patient has a pacemaker. Pace detection choices are PACE 1, PACE 2, and OFF.

PSU Module
The PSU module is an AC Mains to DC converter. The module receives AC power
from the mains input connector. When AC INPUT is applied to the module, the
module AC/DC Converter changes the AC INPUT supply via rectifier circuit to a
high voltage DC. The DC power is then routed through a high frequency
switching converter and regulated to 12 VDC. This supply is connected to the
DC2DC PWA for further regulation.

DC2DC PWA
The PSU supplies regulated DC power to Monitor. The DC2DC PWA is designed to
operate from the output of the AC MAINS PSU module
(+12 VDC), or from an internal NiMH rechargeable battery (+8.4 VDC). The PSU
automatically selects the power source based on the following priority:

Equipment Overview: Theory Of Operation

The +12 V printer supply voltage and AUX +12 V are up converted from VRAW1
and maintained by a boost regulator to +12 V.
VBAT is the battery voltage protected by a 100 mA auto-reset fuse. It is also
used to power the fail-safe alarm circuits on the Main Board.
The DC2DC PWA contains firmware that reports the charge status of the battery
to the secondary processor on the Main Board. The secondary processor
charges the battery at the fastest rate allowable while keeping the Monitor
power consumption under 60 W.
The host communication port control circuitry selects whether Channel 2 is
routed to the Comms connector (DB-9) or the wireless connector (DB-15). If
Channel 2 is routed to the Comms connector, it is configured for RS-232 signals.
Channel 1 and Channel 2 on the wireless connector are only available as
inverted TTL.

Main Board
The Main Board is configured with Flash ROM, EEPROM, RAM, Primary Processor,
Secondary Processor, and NIBP. The Primary Processor operates from a 4.9152
MHz crystal stepped up to 49.152 MHz. The Primary Processor services and
controls the RAM, Flash ROM, EEPROM, the physiological interface modular
devices and display backlighting. The Secondary Processor monitors the power
supply circuit and signals within the NIBP circuits, controls the power-on/off
sequences, and performs watchdog tasks on it and the Primary Processor
monitors. The Secondary Processor monitors the power supply circuit and
controls the battery back up enable when no external sources are present and
shuts down the unit when the battery is exhausted. It enables the battery
charging circuit based on the battery charge status, unit power consumption,
and the availability of an external power source.
The Random Access Memory (RAM) is composed of a SRAM chip and two SDRAM
chips. The 512 Kbytes of battery-backed SRAM is provided to store trend data
and to provide space for working algorithms and is accessed on bits D[0:15] of
the data bus. The two 64-Mbit SDRAM chips are set up to form a 32-bit data bus
on bits D[31:0] that is used for running the program and working memory. This
gives 16 Mbytes of memory with an access time of less that 20 ns. The program
is loaded (including the boot code) from the 16-bit FLASH Read Only Memory
(ROM). The Electronically Erasable Programmable Read Only Memory (EEPROM)
is an 8-bit chip that is used to store the calibration and other "setting" variables
that have to be maintained in the event of a complete power failure.
If a hardware or software error causes a malfunction, its watchdog will provide
an internal and external RESET (L) signal. The FAILSAFE controller causes the
FAILSAFE (L) signal to go low. This signal passes to the Secondary Processor,
which disables the Primary Processor's power supplies, thus turning it off.
FAILSAFE (L) also passes to the control logic, which dumps the cuff pressure. The
system is left in a safe state but remains ON to enable the Secondary Alarm to
stay active. The Primary Processor monitors the activity of the secondary via its
handshaking communications. If the Secondary fails, the Primary can assert the
FAILSAFE line by overriding the FAILSAFE controller. The Secondary Alarm is a
hardwired alarm that will sound in the event of a FAILSAFE condition. Pressing

the OFF-key can immediately reset this alarm although it times-out after about
10 minutes.

SpO2 PWA
The Monitor can be configured with either NELLCOR or MASIMO SET SpO2
hardware in config manager menu. When the Monitor is configured with
NELLCOR hardware, only NELLCOR config manager menu is available; when
the Monitor is configured with MASIMO SET hardware, MASIMO SET config
manager menu is available.
The SpO2 processor monitors the pulse oximetry signal. The processor takes the
signals and derives the oxygen saturation and heart rate data and converts
them into serial data. The serial data from the SpO2 processor is repacked by
DAS board and sent across an isolation barrier (opto couplers) and passed to the
Primary Processor via a dual-channel UART.

UI PWAs
The UI PWAs provide access to the basic functions of the Monitor. The buttons
that control each function are integrated to form a touch pad front panel. The
AC LED is continuously green when an external power source is present or
flashing green when the unit does not recognize the battery. The battery LED is
continuously yellow when the unit is running on battery and flashes yellow
when the battery is low.

DAS PWA
The DAS PWA is composed of ECG and MPDAS. Both ECG and MPDAS are
isolated to earth, and isolated from each other.
ECG accepts signals from a 3-electrode cable or a 5-electrode cable for
processing. The 3-electrode cable provides a single lead configuration with Lead
I, Lead II, or Lead III available. The 5-electrode cable provides a configuration
with Lead I, II, III, aVR, aVL, aVF, VA and displays this waveform as the primary
lead. In 5-electrode configuration, another waveform can be displayed as the
secondary lead.
A hybrid on the PWA provides lead-to-lead defibrillator protection. In addition, a
passive R/C network located on this PWA provides the first stage of high
frequency filtering for EMC and ESU interference rejection. Two electrodes are
selected for ECG measurement by a multiplexer (LS0, LS1 signal controlled) and
passed to a differential amplifier. A second multiplexor selects the third
electrode (the one not sent to the differential amplifier) and drives the signal with
an amplified and inverted version of the common mode voltage of the two
measuring electrodes. This feedback action cancels most of the common mode
signal applied to the differential amplifier. The output signal from the differential
amplifier is then routed to the bandpass filter and pacemaker detection circuit.
The ECG PWA uses the pacemaker detection circuit to prevent pacemaker
signals from interfering with heart rate measurements. The ECG signals are sent

2-12

Revision C

Equipment Overview: Theory Of Operation

through a bandpass filter designed to pass pacemaker pulses in preference to
ECG signals. The filter output is applied to a comparator that asserts an output
signal when the input signal exceeds its positive or negative threshold. This
output signal is used by the controller to blank the ECG signal channel and alert
the host to the presence of a pacemaker pulse. The filtered ECG signal is routed
to the A/D converter for transfer to the Main Board.
The respiration circuit uses the ECG electrodes to measure respiration rate. This
is achieved by applying an excitation current (65.536kHz, well outside the
bandwidth of normal ECG signals) generated by a square wave switch onto two
selected electrodes. The measured voltage drop is filtered, the baseline
component removed, and amplified. The analog voltage representing the
impedance is routed to A/D converter for transfer to the Main Board.
The ECG provides isolated power to its circuitry using an isolation transformer. A
transformer driver drives the transformer primary at a frequency of about 350
KHz. The voltage of the transformer secondary is full-wave rectified using two
Schottky barrier diodes. The isolated voltage is filtered by capacitors and
regulated by a +5 V regulator. Isolated ground is obtained from the center tap of
the transformer. The data transferred from the A/D converter to the host is
isolated using opto couplers.
In the temperature parameter, the Alaris probe and the calibration resistor
chain are connected to an AD7738 24-bit serial DAC, which is read by the micro
controller. The micro controller computes the resistance for the probe (and
associated leads) and transmits the resistance value to the Primary Processor in
a serial data stream.

Pneumatic Control
The pneumatic functional block includes the control signal decode logic, the
valve driver circuitry, the pump driver circuitry, and a safety interlock circuit.
There are two transducers on board, PT1 and PT2. PT1 is used for main readings
while PT2 confirms readings and is used to derive overpressure signals. The
following signals are multiplexed into a 16-bit SAR A/D converter via a
multiplexor:

PT1A - the output of the measurement pressure sensor after

amplification and filtering by means of a passive 1 KHz low pass antialias filter

PT1B - the output of the measurement pressure sensor after

amplification and filtering by means of a passive 20 Hz low pass antialias filter

PT2 - the output of the confirmation/over-pressure sensor after

amplification

TH REF - the voltage that the amplified PT2 has to attain before the
safety circuit cuts in.

VBAT- 1/4 ratio of VBAT voltage

Valve Sense

The 16-bit value out of the ADC is available on the data bus at D[15:0].

Equipment Overview: Theory Of Operation

Control signals for the board are derived via four different sources: direct control
from outputs of the processor, controls signal derived from processor address
write commands (which are stored in an addressable latch), signals derived from
the watchdog timer, and signals generated by the overpressure functional
block. The four valve control signals and the pump control signal are derived
from the write address and stored in an addressable latch. Latch values are
cleared by application of system RESET. Each latch signal is individually gated in
a programmable logic device (XC9572) with the fail safe input signal (watchdog
timer) and the overpressure latch output to ensure pressure is removed from the
patient cuff should either overpressure or processor failure condition occur. A
cross-coupled latch for overpressure is formed with discrete logic included in the
programmable logic device. It is set by the occurrence of an overpressure
condition existing for a period greater than 500 milliseconds. When this
condition occurs, Filter_OVP-0 transitions low setting the latch. The latch output
state is indicated by the Latched-OVP signal. The latch can only be cleared by
the PNEURESET input.

LCD Assembly
The Monitor series uses a TFT active-matrix-color liquid display. The 10.4 inch
diagonal color display area contains 640 x 480 pixels and is backlit by coldcathode fluorescent lamps.
The LCD has the following specific characteristics. These are neither defects nor
malfunctions:

The ambient temperature may affect the display condition of the LCD.

Uneven brightness and/or small spots may be noticed depending on

packaging are damaged, they must be disposed of as advised in this section.

To clean or disinfect the sensor:

1.

Saturate a clean, dry gauze pad with the cleaning solution. Wipe all surfaces
of the sensor and cable with this gauze pad.

2.

Saturate another clean, dry gauze pad with sterile or distilled water. Wipe all
surfaces of the sensor and cable with this gauze pad.

3.

Dry the sensor and cable by wiping all surfaces with a clean, dry gauze pad.

Periodic Maintenance
Integrity of Hoses and Cuffs
When the pneumatic integrity of any NIBP cuff or hose is in doubt, replace the
cuff and hose, and discard the questionable accessories.

Long-Term Storage
If it becomes necessary to store the Monitor for an extended period of time,
remove all attached accessories. Attach the original packing inserts, and place
the Monitor into the original shipping container.
Generally, long-term storage of a nickel-metal hydride battery in either a
charged or discharged condition has no permanent effect on capacity. Capacity
loss due to self-discharge is reversible, and nickel-metal hydride batteries can
recover to full capacity by proper recharging. For example, cycling through
repeated charge/discharge cycles can restore a full capacity of a nickel-metal
hydride battery that was stored at room temperature for up to one year.
Long-term storage at high temperatures can lead to deterioration of seals and
separators and should be avoided.

Periodic Procedures
Perform the test procedures described in every 24 months, or whenever the
accuracy is in doubt.
NOTE:
An internal, 3.6 V NiMH battery acts as an alarm backup and maintains the
nonvolatile RAM memory when the Monitor is off or away from AC mains. A
system alarm message is generated if backup battery replacement is
required.

Maintenance: Periodic Maintenance

Care of Storage Batteries

The Monitor uses one nickel-metal-hydride (NiMH) storage battery. The battery
can be charged at any time without reducing the charging capacity. Take out
the battery pack if storing for long term; over discharge might impair the
battery.

Procedures For First Use

Follow these procedures to condition a new NiMH battery and optimize its
performance:
The internal battery automatically charges when the AC power supply is in use.
NOTE:
When the battery is charged for the first time, the charger may indicate
prematurely that charging is complete. This is normal and can happen with
all rechargeable batteries when first charged.

Battery Charging
The Monitor charges the NiMH battery whenever the AC power supply is in use.
The Monitor automatically senses if the battery needs recharging. Battery
charging continues whenever it's needed while the Monitor is connected to the
AC power supply, even when the Monitor is turned off.

Batteries should be charged before first use or after prolonged periods of

storage for at least 12 hours.

The battery should be charged at room temperature (59F - 86F; 16C 30C).

It is normal for the battery to become warm during charging or after use.

Batteries can be charged or topped-off at any time. It is not necessary to

wait until they are fully discharged.

If the Monitor is idle for extended periods, it should be at least fully charged
and discharged once a month to ensure optimum performance.

Battery Maintenance
Battery should be maintained to prolong its life. Do not monitor patients during
maintenance. Maintenance procedures are as follows:

Revision C

Connect the power cord to the Monitor and the AC wall outlet.

Power the Monitor on and verify the battery is charging.

Power the Monitor off and leave attached to AC power for a minimum of 4
hours (8 hours recommended).

Power the Monitor on and verify the battery charge status. If further
charging is required, power the Monitor off and recheck every 30 minutes
(or longer) until the battery is fully charged.

If the required charge time exceeds 12 hours, replace the battery.

SpO2 Testing
For Monitors With NELLCOR SpO2 NELLCOR recommends use of the SRCMAX Portable Tester for use with the Dash 2500 Monitor equipped with the
NELLCOR SpO2 system.
On occasion when testing the integrity of the NELLCOR oximetry system,
abnormal results may occur when introducing large changes in the pulse rate
and/or pulse amplitude. Extreme changes in the rate sent to the NELLCOR
sensor by the SpO2 simulator may cause the SpO2 algorithm to completely miss
finding the pulse rate. This is an expected result. To work around this,
incrementally step up or down the settings on your SpO2 simulator and allow

Field Replaceable Units: Disassembly Guidelines

Disassembly Guidelines
REPAIR TO THE FRU LEVEL Field repairs are recommended to the field
replaceable unit (FRU) only. Attempting a field repair on a PCB or a factory
sealed component or assembly could jeopardize the safe and effective
operation of the Monitor.
DAS ASSEMBLY Do NOT open the DAS assembly as this breaks the isolation
barrier which may result in patient death or serious injury. The DAS assembly is
a field replaceable unit only. There are NO field repairs or adjustments for the
DAS assembly.
DC2DC ASSEMBLY When removing the GCX plate from the bottom of the
Monitor, clearly identify the screws to ensure the same screws are used to
replace the GCX plate. Screws that are too long will penetrate into the DC2DC
assembly and cause the battery to split or break.
NOTE:
GE recommends that you assemble the Monitor using the NEW fasteners
(screws, washers, etc.) provided in the FRU Kits. Some fasteners, like the
screws with a thread locking coating, are NOT intended to be re-used more
than three times.

Tools Required
A standard set of hand tools is required for disassembly and assembly.

Before Disassembly
Before you disassemble the Monitor, you should ALWAYS do the following tasks.

6-14

1.

Unplug the monitor.

2.

Remove the battery.

3.

Provide appropriate electrostatic discharge protection to prevent damaging

the Monitor.

4.

Be aware that the nonspecific disassembly instructions apply to all monitors

supported by this service manual. Disassembly for specific models of the
Monitor are identified when required.

Dash 2500 Patient Monitor Service Manual

2042481-001

Revision C

Field Replaceable Units: Disassembly Guidelines

Hardware Precautions
When disassembling the Monitor, observe the following guidelines:

Remove the handle assembly, then remove the display assembly to access
the field replaceable units of the display assembly and the main unit.

Note the positions of wires, cables, and different sized screws; marking them
if necessary to ensure they are replaced correctly.

DO NOT kink, pinch, stretch, twist, or tightly fold a flex cable.

Unless otherwise stated, reassemble the Monitor in reverse order of

disassembly.

Electrostatic Discharge (ESD) Precautions

All external connector inputs and outputs of the Monitor are designed with
protection from ESD damage. However, if the Monitor requires service, exposed
components and assemblies contained within are susceptible to ESD damage.
This includes human hands, non-ESD protected work stations and/or improperly
grounded test equipment.
The following guidelines help make a service workstation more resistant to ESD
damage:

Discharge any static charge you may have built up before handling
semiconductors or assemblies containing semiconductors.

A grounded, antistatic wristband (3M PN 2046 or equivalent) or heel strap

should be worn at all times while handling or repairing assemblies
containing semiconductors.

Use properly grounded soldering and test equipment.

Use a static-free work surface (3M PN 8210 or equivalent) while handling or

working on assemblies containing semiconductors.

DO NOT remove semiconductors or assemblies containing semiconductors

from antistatic containers (Velo-stat bags) until absolutely necessary.

Make sure power to an assembly is turned off before removing or inserting a

semiconductor.

DO NOT slide semiconductors or electrical/electronic assemblies across any

surface.

DO NOT touch semiconductor leads unless absolutely necessary.

Semiconductors and electrical/electronic assemblies should be stored only

in antistatic bags or boxes.

Handle all PCB assemblies by their edges.

DO NOT flex or twist the circuit board.

These guidelines may not guarantee a 100% static-free workstation, but can
greatly reduce the potential for failure of any electrical/electronic assemblies
being serviced.

Neonatal Sensor Accuracy

When sensors are used on neonatal subjects as

recommended, the specified accuracy range is increased
by 1 digit, as compared to adult usage, to account for
the theoretical effect on oximeter measurements of fetal
hemoglobin in neonatal blood. For example, MAX-N
accuracy on neonates is 3 digits, rather than 2 digits.

* The MASIMO SET SpO2 parameter with LNOP-Adt sensors has been validated for no motion accuracy in human blood studies on healthy adult
volunteers in induced hypoxia studies in the range of 70-100% SpO2 against a laboratory co-oximeter and ECG monitor. This variation equals plus
or minus one standard deviation. Plus or minus one standard deviation encompasses 68% of the population.
**The MASIMO SET SpO2 parameter with LNOP-Adt sensors has been validated for motion accuracy in human blood studies on healthy adult
volunteers in induced hypoxia studies while performing rubbing and tapping motions at 2 to 4 Hz at an amplitude of 1 to 2 cm and a nonrepetitive
motion between 1 to 5 Hz at an amplitude of 2 to 3 cm in induced hypoxia studies in the range of 70-100% SpO2 against a laboratory co-oximeter
and ECG monitor. This variation equals plus or minus one standard deviation. Plus or minus one standard deviation encompasses 68% of the
population.
The MASIMO SET SpO2 parameter with LNOP-Neo Pt sensors has been validated for neonatal motion accuracy in human blood studies on
neonates while moving the neonates foot at 2 to 4 cm against a laboratory co-oximeter and ECG monitor. This variation equals plus or minus, one
standard deviation. Plus or minus one standard deviation encompasses 68% of the population.
The MASIMO SET SpO2 parameter has been validated for low perfusion accuracy in bench top testing against a Biotek Index 2 simulator and
MASIMOs simulator with signal strengths of greater than 0.02% and a % transmission of greater than 5% for saturations ranging from 70 to
100%. This variation equals plus or minus, one standard deviation. Plus or minus one standard deviation encompasses 68% of the population.

NOTE: Note: LNCS sensors using LNCS cable technology offer nearly the same performance as the LNOP flexcircuit design. The LNOP single patient sensor line is still the industry "gold standard", while LNCS is the best
cabled sensor alternative.

more than 1000 Unity devices.

Preparation
Special Equipment
This procedure requires the installer to have the following:

RJ-45 Cable P/N 418335-00X

Clinical network (Unity Network)

CIC version 3.0.2 or later

Installation of the network module

F-8

Network module Setup

Connect monitor to network:
1.

Turn off the power at the Dash 2500 Monitor.

2.

Connect network cable to the port labeled as Ethernet on the rear of the
Dash 2500 Monitor. Connect the other end of the cable to the clinical
network.

3.

Turn on the power to the Dash 2500 Monitor.

Set up IP address:
The Dash 2500 Monitor is an Ethernet device bounded with an IP address. It
communicates with CIC devices via the clinical network. There are two ways to
set up the IP address:

Default IP address. (If your CIC IP is 126.XXX.YYY.ZZZ, please use this method)
In this method, the Dash 2500 Monitor IP address will be set automatically.
No configuration is needed.
By factory default, the IP address in Dash 2500 Monitor configuration menu
is set as 0.0.0.0. The monitor will automatically generate a default IP
address calculated from its MAC address. This IP address is unique in all GE
Unity devices and follows below formula:
126. XXX. YYY. ZZZ
where the XXX, YYY and ZZZ are the last three numbers of the monitor MAC
address.

NOTE: When using default IP address, the displayed IP 0.0.0.0 showing in

Dash 2500 configuration menu is not the real IP. Customer shall
ignore it.
Specified IP address (If your CIC IP is not 126.XXX.YYY.ZZZ, please use this
method)
In this method, customer shall set the Dash 2500 Monitor IP address
manually.
NOTES
The IP address of the Dash 2500 Monitor must be unique and valid in
the entire clinical network.

The IP address of the Dash 2500 Monitor must be in the same network
address of the intended CIC devices. For example, if the CIC IP address is
172.16.***.*** in a class-B sub-network, the valid IP address range for
monitor is 172.16.0.1~172.16.255.254.

How to set up the specified IP address?

1. Enter the configuration menu (consult Dash 2500 Monitor service
manual Appendix C).

4. Select IP address sub-menu, select each of the four numeric fields and
set the field values by rotating the Trim Knob. Press the Trim Knob after
adjusting each field value to confirm the setting.
NOTE: Dash 2500 monitor cant inspect the duplicate IP address in the
Unity network. If there are other devices with same IP address in
network, the monitor will still send device identification information
to the CIC. This causes the CIC cant read the IP address normally.
So please make sure Dash 2500 monitor uses the unique IP address
in the network when installation.
5. In the Admit Patient menu, select ADULT and enter the bed and unit
number for this Monitor.
6.

Save default changes.

7.

Repeat step 5 for PEDIATRIC and NEONATE modes.

8.

Exit config mode.

Re-set up
To re-set up type for the network function, enter into boot service menus to clear
config memory. For detail steps, refer to Using the Boot Service Menu.
