14.1.6 Custom LED Labels
Each relay provides you space to label its LEDs based
on how you program them. Labels for the preset
annunciations are provided with the relay. The slip of
paper with the labels printed on it slides into the top of
the front panel, which is accessible with the relay
partially pulled forward out of its housing.
14.1.7 Data Communications Port
This serial data port allows you to connect a personal
computer (PC) directly to the relay. This port conforms
to the EIA RS-232 standard. This feature is typically
used in conjunction with WinDIGSI software to view
event logs and target logs, to monitor measured
values, to program the settings, and to analyze
captured waveforms.

Address to view or change its contents. One is to go
