III. RS232 Communications Parameters:
JP5 PINS 7, 8, and 9
Communications Parameters:
A. Baud Rate 115,200
B. No Parity
C. 1 Start Bit 1 Stop Bit
NOTE if you are using communications software different from the one supplied with the controller: The
demands of temperature control require a relatively large portion of the processing power of the onboard
microcontroller. It is possible for a host computer to send data too quickly for the controller to receive and
update. If communications is disrupted are disrupted after repeated queries, TE Technology recommends
adding a delay between each command sent to allow the controller sufficient time to process and respond
to the query.
