When a port is configured for RS-232 operation, you can connect
compatible serial communication devices using common RS-232
cables. Refer to the table below for signal designations and Figure
4.11 for cable recommendations. Refer to the IMC S Class Motion
Control Installation and Setup Manual (publication 999-122) for
multidrop application instructions.
Important: The RTS/CTS and DSR/DTR signals are internally
jumpered to allow you to use standard RS-232 cables
with serial devices requiring hardware handshaking.
