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.
