1.4.2 COMMUNICATIONS
The EnerVista UR Setup software communicates to the relay via the faceplate RS232 port or the rear panel RS485 / Ether-
net ports. To communicate via the faceplate RS232 port, a standard straight-through serial cable is used. The DB-9 male
end is connected to the relay and the DB-9 or DB-25 female end is connected to the computer COM2 port as described in
the CPU communications ports section of chapter 3.
Figure 1–12: RELAY COMMUNICATION OPTIONS
To communicate through the C30 rear RS485 port from a computer RS232 port, the GE Multilin RS232/RS485 converter
box is required. This device (catalog number F485) connects to the computer using a straight-through serial cable. A
shielded twisted-pair (20, 22, or 24 AWG) connects the F485 converter to the C30 rear communications port. The converter
terminals (+, –, GND) are connected to the C30 communication module (+, –, COM) terminals. See the CPU communica-
tions ports section in chapter 3 for details. The line is terminated with an R-C network (that is, 120 Ω, 1 nF) as described in
the chapter 3.
1.4.3 FACEPLATE DISPLAY
All messages are displayed on a backlit liquid crystal display (LCD) to make them visible under poor lighting conditions.
While the keypad and display are not actively being used, the display defaults to user-defined messages. Any high-priority
event-driven message automatically overrides the default message and appears on the display.
