Interface Cable Pinouts
You need to build an interface cable between your PLC and the modem or printer. The actual cable is connected to the Port which is supported by the PLC and to the RS232 port of the modem or printer, or direct to another PLC's Modbus port. Because the XXMIT supports many modems and printers the pinouts are going to vary. Some pinouts are provided below.
9-pin (RS-232) to 25-pin (Modem) with no RTS/CTS Control
Refer to the figure for Front Views of Connectors.
Refer to the Connector Pinouts table.
