Warner Electric CBPC-3590 - Manual (Page 16)

16 Warner Electric • 800-825-9050 P-921-1 • 819-0526
Note: To make changes in Parity or Baud Rate
power must first be removed and reapplied after
program changes to either are made . Both Parity
and Baud Rate are initialized when the control
“powers up”.
Command Characters
Command Characters mimic the operation of the
keypad. Below is a list of the serial equivalents of
the keypad keys.
Control Characters
Two control characters are used to start and stop
the transmission from the CBPC-3590 control.
They are shown below:
(CTRL) S Suspends transmission following
the completion of a line being sent .
The driver will then be turned Off.
(CTRL) Q Resumes transmission from a unit
that had been turned Off. The RUN
mode line currently selected will be
continuously updated .
The character format is as follows:
Start bit (“low” logic level)
ASCII data (7 bits), least to most significant
Parity bit (programmable)
Stop bit (“high” logic level)
Parity Bit
The parity bit is programmable as “Odd,” “Even,”
or “No” parity. Odd and Even parity force the total
number of data bits to be an even or odd for data
that is transmitted by the CBPC-3590 control.
Incoming parity is always compared to the
calculated parity. Characters with parity errors are
discarded. If No parity is selected incoming parity
is ignored. Characters are transmitted with Odd or
Even parity as selected on line 25 of the program
table. If No parity is selected then “high” bit is
added as an extra stop bit .
Baud Rate
Select the baud rate to match the device
communicating with the control. You may select:
300, 600, 1200 or 2400 baud on line 24 of the
program table . Baud rate is common to both
transmitter and receiver .
Line Format
The CBPC-3590 control transmits only complete
lines. The driver is turned off when not
transmitting causing the bus to enter a “float”
state, ignoring data on the bus during this “float”
time. Unless otherwise commanded the
CBPC-3590 control continuously transmits the
Count Value. The line format is as follows:
- a carriage return at the beginning of a line
- a prefix indicating RUN, SETUP, or PROGRAM
- a unique line mnemonic
- a five digit data field with decimal point
- a carriage return at the end of the line
