GENERAL SYSTEM INSTALLATION
DEVICE LOCATIONS
The physical locations for the Power Cab
TM
can be anywhere. We suggest a location
where the LED on the front of the Power Panel can be easily seen should there be a
problem. Cab Bus panels such as the UTP or UTP-DIN are set up to use prewired
four or six wire RJ12 telephone type cables to connect from panel to panel behind
the layout fascia. Page 21 has a diagram of the proper wiring for these cables. We
recommend placing the panels about 7-8 feet apart. In yard areas closer spacing
may be needed. We suggest that a plug be no more than three feet from any siding
where an operator would most likely stop and spend some time. Consider that
operators will tend to gather at these panels so placement in crowded aisles may
require care.
A SEPARATE PROGRAMMING TRACK
The programming track is a separate section of track where programming (setting
the locomotive address and/or other internal parameters) takes place. The
programming track must be electrically separate from the main trackage. The end of
a convenient spur track will work fine. Install insulated joiners in both rails, directly
across the track from each other. Allow enough length for your longest locomotive.
If desired, the programming track can be connected with a double-pole double-throw
switch that is used to isolate this segment from the rest of your layout. This track is
needed to complete the necessary start up programming for most decoder-equipped
locos.
When the switch is set to use the programming track, the remainder of the layout is
stopped. With NCE decoders, all parameters can be changed on the mainline using
the “Programming on the Main” feature, without shutting down the whole layout.
Some other manufacturer’s decoders do not support “Programming on the Main” so
a programming track is required. Some owners have setup their shop loop to be DC,
DCC, and programming track, then they can do all the testing in their shop and have
only ready-to-run loco’s on the layout.
