3.2 WIRING
A 9-pin RS232C serial port is located on the L30 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.
