A Gallagher Electric Fence Monitor can be connected to C3 unit by:
Connecting the wiring to the RS485-1 or RS485-2 Port.
There is no need to set the Power Output. It should remain as "none".
The Observant C3+ when connected to a Gallagher Fence monitoring device has the ability to connect multiple fencing zones when connected through the Gallagher electric fence energiser and Gallagher fence monitor.
The monitor will connect to the C3+ and the Gallagher units are set to poll the system for an update on the status of the fence zones once every 24 hours, meaning they give a constant reading of the state of charge of the electric fence in Global.
If something makes contact with the electric fence in a fence zone, the Gallagher fence monitor will detect this change in status, and this will be represented in Global.
