is either 0 or 1. This setting controls the function of the COM LED on the LS8000-3.
This is a Blue-Orange LED on top of the gauge that indicates communications status. This
value should be set to 0 if your LS8000-3 does not have the Ethernet option installed.

The Orange LED blinks when the LS8000-3 sees activity on the RS-232 or RS-422 receive
lines. This does not indicate that the LS8000-3 understood the message, only that it saw the
voltage change (the baud rate may be incorrect.) This is a diagnostic feature to allow easy
wiring verification.
The Blue LED blinks when the LS8000-3 transmits on either the RS-232 or RS-422 ports. If
the light is continuously blue, then the LS8000-3 is transmitting continuously.
When orange and blue are lit at the same time, the LED is white.
