To connect the TV-UCXP683T-V to the Ethernet
Connect an Ethernet cable from the building BAS system or another TV-UCXP683T-V controller to the Eth0
Ethernet port. If necessary, connect another Ethernet cable from the Eth1 port to the next TV-UCXP683T-V
controller in a daisy chain.
The TV-UCXP683T-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.
To wire to a BACnet MS/TP network
An MS/TP network can be wired to
Port S1
.
1
Turn
off
the TV-UCXP683T-V's power.
2
Check the communications wiring for shorts and grounds.
3
Connect the communications wiring to
Port S1
’s screw terminals labeled
Net +
,
Net -
, and
Shield
.
NOTE
Use the same polarity throughout the network segment.
4
Set
Port S1
to
MS/TP
on the controller setup pages >
BACnet
tab >
Port S1
.
5
If the TV-UCXP683T-V is at either end of a network segment, set the port's
End of Net?
switch to
Yes
.
NOTE
The controller’s
End of Net
switch applies network termination and bias. If the controller is at the end
of a network segment that includes a DIAG485 that has its
Bias
jumper in the ON position, set the
End of
Net?
switch to
No
and connect a 120 ohm termination resistor to the
Net+
and
Net-
terminals. See
DIAG485
Technical Instructions
for more information.
6
Turn on the controller's power.
To wire a third-party device
BACnet
: You can wire a third-party BACnet device to the TV-UCXP683T-V's
Eth0
,
Eth1
port or
Port S1
. See the
BACnet Integration Guide
for the TV-UCXP683T-V.
Modbus
: You can wire a third-party Modbus master or slave device to
Port S1
. See
Modbus Integration Guide
for
the TV-UCXP683T-V.
