7.6 Modbus Application Port Connection
The module supports RS-232, RS-422, and RS-485 wiring to remote devices.
7.6.1 RS-232 Wiring
When the RS-232 interface is selected, the use of hardware handshaking
(control and monitoring of modem signal lines) is user definable. If no hardware
handshaking will be used, here are the cable pin-outs to connect to the port.
RS-232: Modem Connection (Hardware Handshaking Required)
This type of connection is required between the module and a modem or other
communication device.
The "Use CTS Line" parameter for the port configuration should be set to 'Y' for
most modem applications.
