RS-485 Connections
The RS-485 connections are located on a terminal block shared with the IRIG-B terminals. The three RS-485
terminals will mate with a standard communication cable. A twisted-pair cable is recommended. Connector
pin numbers, functions, names, and signal directions are shown in Table 7-2. A cable connection diagram
is provided in Figure 7-14.

Communication Settings
Communication settings are the formal set of conventions controlling the format and relative timing of
message exchange between two communications terminals. Relay settings are stored as RATEDPS, where
RATE = baud rate (300 to 19.2k), D = number data bits (7 or 8), P = parity (O, E, or N), and S = stop bits (1
or 2). The default protocol is 96008N1.
Setup
To initially prepare the relay for communications, go to the MAINTENANCE menu and set the proper settings
for the front and rear port or use the COMx command through the communication port with the initial settings
set for the proper mode as shown in the front panel maintenance menu.
