Review all WARNINGS and CAUTIONScarefully.1.4.2 COMMUNICATIONSThe 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 maleend is connected to the relay and the DB-9 or DB-25 female end is connected to the PC COM1 or COM2 port as describedin the CPU Communications Ports section of Chapter 3.Figure 1–4: RELAY COMMUNICATIONS OPTIONSTo communicate through the F60 rear RS485 port from a PC RS232 port, the GE Multilin RS232/RS485 converter box isrequired.

A shieldedtwisted-pair (20, 22, or 24 AWG) connects the F485 converter to the F60 rear communications port. The converter termi-nals (+, –, GND) are connected to the F60 communication module (+, –, COM) terminals. Refer to the CPU Communica-tions Ports section in Chapter 3 for option details. The line should be terminated with an R-C network (i.e. 120 Ω, 1 nF) asdescribed in the Chapter 3.1.4.3 FACEPLATE DISPLAYAll messages are displayed on a 2 × 20 character vacuum fluorescent display to make them visible under poor lighting con-ditions.
