General Information
ICES-003, Issue 4:2004
Mounting
The Tracer™ UC400 controller is factory installed in the VAV control box.
Setting up the Tracer UC400 Controller on a BACnet Link
Tracer SC and BACnet Communications Link Wiring
Use 18 AWG shielded communication wire for BACnet MS/TP installations. Limit BACnet MS/TP
wiring links to 4,000 ft. There is a 60 device maximum per link (without a repeater). Two BACnet
links are available on the SC. Connect the BACnet link to the Tracer UC400 controller terminals
labeled Link. Incoming wires can be connected to the first two terminals, and the outgoing wires
can be connected to the second set of terminals, such that there is only one wire per termination.
Refer to Chapters 2 and 3 for further information about wire selection. See also wiring guide BAS-
SVN03*-EN (Unit Controller Wiring for Tracer SC™System Controller) for required wire type,
topology, and active termination resistors for BACnet links.
Rotary Switches
There are three rotary switches on the front of the Tracer UC400 controller (see Figure 3, p. 16). Use
these switches to define a three-digit address when it is installed in a BACnet system (for example,
107, 120, and so on), whether with other Trane BACnet controls or controls from another vendor.
This three-digit rotary switch setting is used as both the BACnet MAC address and the BACnet
Device ID.
Note: Valid addresses are 001 to 120.
Important: Each Tracer UC400 controller on the BACnet link must have a unique rotary switch
setting, otherwise communication problems will occur.
Tracer UC400 Controller Features
Controller Interface Flexibility
The Tracer UC400 controller allows VAV units to communicate on a BACnet MS/TP link. This
controller works in standalone mode, peer-to-peer with one or more other units, or when
connected to a Tracer SC or a 3rd party building automation system that supports BACnet.
