Procedure
Using the RS-232 Serial Port (ESP and EX only)
When using RS-232, a 3-wire connection is sufficient to communicate with the ESP or EX processors
(use of the CTS/RTS pins on the ESP is optional). ESP Processors use a 9-way D connector configured as
DTE, so a crossover (or null-modem) cable will be required to connect directly to a PC, whereas the EX
processors use a miniature Phoenix connector and can be wired as required.
The default communication settings are shown below. If required these settings can be changed via
ControlSpace Designer™ software.
With a Terminal Program like "Clear Terminal" etc. you are able to control the ESP/EX Processors by using our Serial Control Protocol.
