Changing Terminator Switch Settings
The terminator switch for the RS-485 “TO MONITORS” connector is shipped from the factory in the terminated
or “IN” position. This is the correct setting if the ADM800 is connected to only one AGM300, or if it is the last
device on a network chain. If the ADM800 is being installed in the middle of a network, the terminator must be
moved to the “OUT” position. Refer to
Multiple AGM's
on Page 12.
The terminator switch for the RS-485 “TO HOST” connector is shipped from the factory in the terminated or “IN”
position. This is the correct setting if the ADM800 is the last device on the network chain. If other devices are
daisy chained through the ADM800, the terminator must be moved to the “OUT” position. Refer to
Connecting
to a Building Management System
on Page 12.
Locate each terminator switch and determine its position. If it needs to be moved, carefully slide the switch to
the proper position.
