Cabling for RS-232 Serial Protocol:
The controller functions as Data Terminal Equipment (DTE) devices. When
the controller is connected to another DTE device (such as a personal
computer), a null modem serial cable or a simple three wire serial crossover
cable is required to connect the devices. The null modem cable swaps the
signal lines so the receive and transmit signals are properly connected.
Note:
For-RS 232, the serial cable between the PC and the controller only needs to cross Rx
and Tx pins. No other signals are needed, except ground pin 5.
