Dcc Input Terminal Strip - PRICOM Design Layout Lighting Solution User Manual

Layout Lighting Solution – Connections
The cables are 6-wire Modular cables and can be flat or twisted pairs. PNET cables
include 12VDC power that comes in very handy for the PNET Control Output as the
12VDC on the cable can power many of the smaller PNET boards.
PNET Cables should be wired as "Straight Through" and not "flip" anywhere along the
path. Nothing will be damaged if a cable is reversed, but the PNET Communications
Data lines would be reversed making PNET malfunction. PNET cables can be plugged or
un-plugged with the power on.

We have included a terminator with your kit. There needs to be at
least ONE terminator in order for PNET to function. Ideally, there
should be a terminator at each end of your PNET Bus.
To create your own terminators, simply put a single 120 Ohm resistor between the
Place one of these termination resistors at each end of the PNET bus.

3.4 DCC Input Terminal Strip

Another key feature of the Layout Lighting Solution is the ability to trigger events from
DCC mobile or accessory commands. To facilitate this connection, we provided a DCC
Input Interface. This input is NOT isolated, so it is important to keep the Ground of all
systems the same. The DCC System Ground should be attached to the "G" terminal of P6
in order to reduce the chance of noise and grounding issues. Since DCC is not polarity
sensitive, the "N" and "P" terminals can be reversed, but the Negative and Positive
terminals are as follows:
