RS-232: Null Modem Connection (No Hardware Handshaking)

This type of connection can be used to connect the module to a computer or field
device communication port.

Note:

If the port is configured with the "Use CTS Line" set to 'Y', then a jumper is

required between the RTS and the CTS line on the module connection.
