A22KPOE Wiring Diagram
From PoE+ source
(Data + Power)
Ethernet @ 10/100 Mbps
Maximum 100m (300ft.)
Furthest RS485 module at
maximum 1220m (4000 ft).
RS485 Port
The RS485 port is used to connect
and communicate with an A22K set
as "Expander" or any RS485
ATRIUM modules.
Up to 4 A22K set as "Expander"
can be connected per RS485 port.
We highly recommended to use a
twisted pair wiring as shown below.
It will avoid any communication
problem that may occur in noisy
environments.
