6.2.1 Configuring Serial Communications
Before starting, verify that the serial cable is properly connected to either the RS232 port
on the front panel of the device (for RS232 communications) or to the RS485 terminals on
the back of the device (for RS485 communications).
This example demonstrates an RS232 connection. For RS485 communications, the GE
Multilin F485 converter will be required. Refer to the F485 manual for additional details. To
configure the relay for Ethernet communications, see
