Introduction To DCS
Recommended Wiring Method
It is important for good operation to make the most efficient use of the power and digi-
tal signal available on your track. Poor wiring and bad connections offer resistance and
can interfere with receipt of the DCS signal and limit the number of engines and cars
you can run on your track. Be sure to use proper wire (we recommend 16-gauge or larg-
er paired wire, like speaker wire) and good connections (good connections mean crimp or
solder).
Because center rail blackening is not conductive, you may find that the blackening on
your track creates resistance that drains power and signal. If so, use Scotch-Brite®, fine-
grit sandpaper, or an LGB® track cleaning block to clean the blackening off the top of
your center rail.
Advanced wiring information and diagrams, including wiring for layouts using blocks for
conventional operation, are located in the “Universal Locomotive and Accessory
Operation” section of this manual.
Optimal Performance Wiring Principles:
-
Use 16-gauge or larger paired wire (such as speaker wire)
-
Use a star pattern (home run wiring) to wire directly from the TIU to each
lock-on
-
Use a terminal block to carry power and signal from one TIU channel to
multiple lock-ons
-
Avoid common bus wiring
-
Solder for tight connections (not required)
-
Clean the blackening off the top of the center rail (if necessary)
-
Power accessories and turnouts via auxiliary, not track, power
-
Place a lock-on (or wire directly to track) approximately every 25 linear feet,
both center and one outside rail
