Commercial Self-Contained (CSC) and
IntelliPak CSC Interfaces

Description

Interfaces for the commercial self-contained (CSC) and IntelliPak CSC
provides a communication link between each CSC and the BCU. There
are two generations of CSC UCMs. The first generation is simply referred
to as CSC. The current generation is based on the IntelliPak UCM plat-
form and is referred to as IntelliPak CSC. For specific information about
the number of CSCs allowed per BCU and per communication link, refer
to Table 7 on page 46.

Type of Communication Card: Isolated Comm3

Refer to "Isolated Comm3 Card" on page 49.

Wiring Notes

To establish connections between the UCM and the BCU, Trane requires
that you use the communication-link wiring specified in this manual. For
wire selection specifications, see "UCM Communication-Wire Character-
istics" on page 55.
Use fiber-optic modems for building-to-building communication. If fiber
optics are not used, building-to-building communication wiring requires a
Transtector transient protector at each building. You can purchase Tran-
stector protectors through Trane. Contact your local Trane sales office for
details.
In a daisy chain configuration, use one pair of wires that start at the BCU
and go to all UCMs in a continuous loop. A branch configuration is possi-
ble if you need to tap into a daisy chain. Limit the total aggregate length
of the wiring for each communication link to 5,000 ft (1,524 m).
To connect communication wiring:
1. Attach one end of the communication-link wiring to TB2 on the BCU.
For the location of TB2, refer to Figure 16 on page 47.
2. For the CSC, attach the other end of the communication-link wiring
to the CSC UCM at TB2-1 (TB2-1 is a terminal block located in the
CSC control panel). Refer to the CSC literature for connection points.
For the IntelliPak CSC, attach the other end of the communication-
link wiring to the UCM at the communication link + and – terminals
(see Figure 35 on page 73). For more detailed information on wiring
the Intellipak CSC, refer to the CSC installation literature.
