To Connect The Tv-Uc253-V To The Ethernet - Carrier TruVu UC253-V Installation And Startup Manual

To connect the TV-UC253-V to the Ethernet

Connect an Ethernet cable from the building BAS system or another TV-UC253-V controller to the Eth0 Ethernet
port. If necessary, connect another Ethernet cable from the Eth1 port to the next TV-UC253-V controller in a daisy
chain.
The TV-UC253-V 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.
