7.6 Modbus Application Port Connections

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

communication device.

The "Use CTS Line" parameter for the port configuration should be set to 'Y' for

most modem applications.
