3.2.8 RS232 FACEPLATE PORT
A 9-pin RS232C serial port is located on the T60 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.

3.2.9 CPU COMMUNICATION PORTS
a) OVERVIEW
In addition to the faceplate RS232 port, the T60 provides two additional communication ports or a managed six-port Ether-
net switch, depending on the installed CPU module. In the following table, multiple Ethernet ports are supported, but only
one can be used at a time. For example, the 10Base-F (normal) port and 10Base-T (alternate) port are supported in the 9G
module, but only one can be used at a time.
The CPU modules do not require a surge ground connection.
