WARNINGS
•
Do not apply line voltage (mains voltage) to the controller's ports and terminals.
•
Do not exceed the minimum bend radius of the Cat5e or Cat6e Ethernet cable. Refer to Ethernet cable
manufacturer specifications for minimum bend radius.
To connect the TV-UC683T to the Ethernet
Connect an Ethernet cable from the building BAS system or another TV-UC683T controller to the Eth0 Ethernet
port. If necessary, connect another Ethernet cable from the Eth1 port to the next TV-UC683T controller in a daisy
chain.
The TV-UC683T has a fail-safe Ethernet relay that bypasses a daisy chained controller in the event of an internal
disruption, such as a power loss. When a failure occurs and the switch is bypassing a controller, the network
connection on both sides of the controller are electrically connected, which continues the signal and passes it to
the next controller.
NOTE
If your system has controllers on different IP subnets separated by an IP router, you must configure one
controller on each subnet as a BACnet Broadcast Management Device (BBMD). Do not configure more than one
BBMD per subnet as this may cause circular routes. See "Setting up BACnet Broadcast Management Devices
(BBMDs)" in SiteBuilder or i-Vu® Help.
