3.2 WIRING
A 9-pin RS232C serial port is located on the C30 faceplate for programming with a personal computer. All that is required to
use this interface is a personal computer running the EnerVista UR Setup software provided with the relay. Cabling for the
RS232 port is shown in the following figure for both 9-pin and 25-pin connectors.
The baud rate for this port is fixed at 19200 bps.

a) OPTIONS
In addition to the faceplate RS232 port, the C30 provides two additional communication ports or a managed six-port Ether-
net switch, depending on the installed CPU module.
The CPU modules do not require a surge ground connection.
