ports
1. Rotary Switches for setting BACnet® MAC address
or MODBUS® ID.
2. LINK for BACnet® MS/TP, or MODBUS® Slave (two
terminals, ±). Field wired if used.
3. LINK for BACnet® MS/TP, or MODBUS® Slave (two
terminals, ±). Field wired if used.
4. Machine bus for existing machine LLIDs (IPC3
Tracer bus 19.200 baud). IPC3 Bus: used for Comm
4 using TCI or LonTalk
®
using LCI-C.
5. Power (210 mA at 24 Vdc) and ground terminations
(same bus as Item 4). Factory wired.
6. Not used.
7. Marquee LED power and UC800 Status indicator
(Table 14, p. 48).
8. Status LEDs for the BAS link, MBus link, and IMC
link.
9. USB device Type B connection for the service tool
(Tracer® TU).
10. The Ethernet connection can only be used with the
Tracer® AdaptiView™ display.
11. USB Host (not used).
Communication Interfaces
There are four connections on the UC800 that support
the communication interfaces listed. Refer to Figure
29, p. 47 for the locations of each of these ports.
• BACnet® MS/TP
• MODBUS® Slave
• LonTalk® using LCI-C (from the IPC3 bus)
• Comm 4 using TCI (from the IPC3 bus)
Rotary Switches
There are three rotary switches on the front of the
UC800 controller. Use these switches to define a three-
digit address when the UC800 is installed in a BACnet®
or MODBUS® system (e.g., 107, 127, etc.).
NNoottee:: Valid addresses are 001 to 127 for BACnet
®
and
001 to 247 for MODBUS
®
.
LED Description and Operation
There are ten LEDs on the front of the UC800. The
following figure shows the locations of each LED and
the following table describes their behavior in specific
instances.
