<N> 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.

RS-232/RS-422 Traffic

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.
