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.
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.
Modules 9G, 9H, 9L, and 9M are no longer available.

For the 9G/9H CPU, the 10Base-T port can only be used when the CH1 10Base-F fiber has been removed. The
10Base-T Ethernet cable and the CH1 10Base-F fiber cable cannot both be installed at the same time.
For the 9J/9K CPU, the 10/100Base-T port has the lowest priority and is only active if both CH1 and CH2 fiber links
are down. Installation of the 10/100Base-T Ethernet cable at the same time as the CH1 and/or CH2 100Base-F
fiber cables does not affect the communication over the CH1 or CH2 fiber ports.
