3.2.6 RS232 FACEPLATE PORT
A 9-pin RS232C serial port is located on the B90 faceplate for programming with a computer. All that is required to use this
interface is a 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
.

3.2.7 CPU COMMUNICATION PORTS
a) OPTIONS
In addition to the faceplate RS232 port, the B90 provides a rear RS485 communication port.
The CPU modules do not require a surge ground connection.

b) RS485 PORTS
RS485 data transmission and reception are accomplished over a single twisted pair with transmit and receive data alternat-
ing over the same two wires. Through the use of the port, continuous monitoring and control from a remote computer,
SCADA system, or PLC is possible.
