Ethernet Network Connection & Rs485 Bus - CDVI ATRIUM A22K Manual

ETHERNET NETWORK CONNECTION & RS485 BUS
The ATRIUM A22K provides a 10/100Mbps Ethernet port to allow direct connection to a PC or to a LAN/WAN.
Connect the Ethernet 10/100 Mbps port of the ATRIUM A22K to a LAN or WAN network using an UTP cable
(maximum 100m (300ft)). Connect expansion modules on a 3 conductor RS485 communication loop in daisy
chain or star configuration up to 1220m (4000 ft) from the ATRIUM A22K controller.

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.
