 Crimson Programming Software
Crimson software is a Windows® based program that allows configuration of
the PAX meter from a PC. Crimson offers standard drop-down menu commands,
that make it easy to program the meter. The meter’s program can then be saved
in a PC file for future use. A PAX serial option card or PAX USB programming
card is required to program the meter using the software. Crimson can be
downloaded at www.redlion.net.

Installation Environment
The unit should be installed in a location that does not exceed the operating
temperature and provides good air circulation. Placing the unit near devices
that generate excessive heat should be avoided.

current ratings. All cabling should conform to appropriate standards of good
installation, local codes and regulations. It is recommended that the power
supplied to the meter (DC or AC) be protected by a fuse or circuit breaker.
When wiring the meter, compare the numbers embossed on the back of the
meter case against those shown in wiring drawings for proper wire position.
Strip the wire, leaving approximately 0.3" (7.5 mm) bare lead exposed (stranded
wires should be tinned with solder.) Insert the lead under the correct screw-
clamp terminal and tighten until the wire is secure. (Pull wire to verify
tightness.) Each terminal can accept up to one #14 AWG (2.55 mm) wire, two
#18 AWG (1.02 mm), or four #20 AWG (0.61 mm).

CAUTION: Sensor input common is NOT isolated from user input common. In order to preserve the safety of the meter application, the sensor input

If not, hazardous voltage may be present at the User Inputs and User Input Common terminals. Appropriate considerations must then be given
to the potential of the user input common with respect to earth ground; and the common of the isolated option cards with respect to input common.

be installed into the PAX (see Ordering Information). Depending on the card installed, there will be two or four setpoint outputs
available. For setpoint hardware and wiring details, refer to the bulletin shipped with the option card. For maximum input frequency,
unused Setpoints should be configured for  action.

COMMAND RESPONSE TIME Timing Diagrams
The meter can only receive data or transmit data at any one time (half-duplex
operation). During RS232 transmissions, the meter ignores commands while NO REPLY FROM METER
transmitting data, but instead uses RXD as a busy signal. When sending
commands and data to the meter, a delay must be imposed before sending Command Unit
another command. This allows enough time for the meter to process the String Response
command and prepare for the next command. Transmission Time
At the start of the time interval t1, the computer program prints or writes the
string to the com port, thus initiating a transmission. During t1, the command Ready t1 t2 Ready
characters are under transmission and at the end of this period, the command
terminating character (*, $ or slave only <CR>) is received by the meter. The Command
time duration of t1 is dependent on the number of characters and baud rate of Terminator
the channel. Received
t1 = (10 times the # of characters) / baud rate
At the start of time interval t2, the meter starts the interpretation of the
command and when complete, performs the command function. This time RESPONSE FROM METER
interval t2 varies from 2 msec to 15 msec. If no response from the meter is
expected, the meter is ready to accept another command. Command Unit
If the meter is to reply with data, the time interval t2 is controlled by the use String Response
of the command terminating character and the Serial Transmit Delay parameter Transmission Time
(dELAY). The ‘*’ or ‘<CR>’ terminating character results in a response time Ready t1 t2 t3 Ready
window of the Serial Transmit Delay time (dELAY) plus 15 msec. maximum. The
dELAY parameter should be programmed to a value that allows sufficient time for Command First Reply
the release of the sending driver on the RS485 bus. Terminating the command Terminator Character Transmission
line with “$” results in a response time window (t2) of 2 msec minimum and 15 Received of Reply Time
msec maximum. The response time of this terminating character requires that
sending drivers release within 2 msec after the terminating character is
received.
At the beginning of time interval t3, the meter responds with the first
character of the reply. As with t1, the time duration of t3 is dependent on the
number of characters and baud rate of the channel. At the end of t3, the meter is
ready to receive the next command.
t3 = (10 times the # of characters) / baud rate
The maximum serial throughput of the meter is limited to the sum of the
times t1, t2 and t3.

COMMUNICATION FORMAT
Data is transferred from the meter through a serial communication channel.
In serial communications, the voltage is switched between a high and low level
at a predetermined rate (baud rate) using ASCII encoding. The receiving device
reads the voltage levels at the same intervals and then translates the switched
levels back to a character.
The voltage level conventions depend on the interface standard. The table
lists the voltage levels for each standard.
LOGIC INTERFACE STATE RS232* RS485*
1 mark (idle) TXD,RXD; -3 to -15 V a-b < -200 mV
0 space (active) TXD,RXD; +3 to +15 V a-b > +200 mV
* Voltage levels at the Receiver

Data is transmitted one byte at a time with a variable idle period between
Character Frame Figure
characters (0 to ∞). Each ASCII character is “framed” with a beginning start bit,
an optional parity bit and one or more ending stop bits. The data format and
baud rate must match that of other equipment in order for communication to
take place. The figures list the data formats employed by the meter.
Parity bit
After the data bits, the parity bit is sent. The transmitter sets the parity bit to
a zero or a one, so that the total number of ones contained in the transmission

remaining data bits. The receiving device then reads each bit position as they are

sets the parity bit to odd, even or none (mark parity) for outgoing data.

Stop bit
The last character transmitted is the stop bit. The stop bit provides a single bit
period pause to allow the receiver to prepare to re-synchronize to the start of a
new transmission (start bit of next byte). The receiver then continuously looks
for the occurrence of the start bit. If 7 data bits and no parity is selected, then 2
stop bits are sent from the PAXI.
