Installation Information
See the Digitrax Decoder Manual for complete decoder test procedures, instal-
lation instructions, programming and technical information. Digitrax manuals
and instructions are updated periodically. Please visit www.digitrax.com for the
latest versions, technical updates and additional locomotive-specific installation
instructions.
CAUTION: Programming and layout track must not exceed
16V when using this decoder.
Installation Instructions
1. Carefully remove the locomotive shell from the frame following the
manufacturer’s instructions. Notice the orientation of the shell to the frame
so that you can reinstall correctly.
2.
The DN166PS uses the DNWHPS Digitrax Easy Connect 8 Pin Harness
System which consists of a 2.0” harness that has a Digitrax 8-pin plug on one
end and a DCC medium plug on the other. Remove the jumper plugs from
the DCC medium socket on the factory light board and plug in the DCC plug
end of the harness.
3. For a wired connection in locos that do not have a DCC medium plug, cut the
wires from the DCC medium plug and attach them as described. On the 8 Pin
Track, Motor and Function Harness solder the Red and Black track leads to
the locomotive track power connections. Next solder the Orange and Gray
motor leads to the isolated motor connections. Motor connections must be
isolated from the track connections.
4. Connect any function leads that are to be used for e.g. lights. Insulate any
unused function leads so they cannot short to the locomotive frame or track
power.
5.
Inspect the installation before testing and replacing the shell. In particular
be sure that wires are correctly soldered and routed and that the motor leads
are not shorted to the frame or track.
6.
Replace the loco shell. You are now ready to run your locomotive. The
DN166PS is factory programmed to address 03. You can easily customize
the address and other features. See section “Customizing Your Decoder” that
follows.
Caution: To prevent damage to your decoder and locomotive, track voltage
used during operation must not exceed the operating parameters of the
locomotive and its lighting system in which the decoder is installed (typically
this is 12V DC). For most N scale layouts, Digitrax recommends using 14 volts
DCC or less for operation to avoid damage to the locomotive shell, lamps and
decoder.
