ADDING AFTERMARKET, TRACK-POWERED
NMRA DCC OPERATION
If your NMRA-compliant DCC decoder is designed for full plug-and
play operation with the plug-and-play socket, remove the (DC) Jumper
PC Board and replace it with your plug-and-play decoder. If your
decoder is not designed for full plug-and-play operation, use the
supplied Jumper PC Board with wires (Figure 24) and attach the
wires to your decoder following the instructions that come with your
decoder. Note: the decoder’s “+” and “–” outputs must be connected to
the (DC) Jumper PC Board (+ to B+ [blue wire] and - to Gnd [small
black wire]) to allow the internal lighting and chuff system to function properly.
ADDING AFTERMARKET, ON-BOARD BATTERY/RC OPERATION
If your Battery/RC or DCC Direct system supports plug-and-play using the plug-and-play socket, remove the (DC)
Jumper PC Board from the socket and replace it with the plug-and-play board of your choice. Install the batteries in the
tender next to the main PC board or in a trailing car. Connect the batteries to the “BATT1” battery screw terminals on
the tender’s main circuit board (Figure 25) and switch the “Track/Battery” pickup switch to Battery (Figure 18). Note:
if your Battery/RC or DCC Direct system does not provide DC power to the locomotive’s ground and B+ connections,
then it will be necessary to also connect the battery to the “J1-7 GND” and “J1-6 B+” connections to power the
locomotive’s internal functions (Figure 20). If your Battery/RC system does not support plug-and-play operation, use
the supplied Jumper PC Board with wires and attach the wires to your Battery/RC or DCC Direct system following the
instructions that come with your system. Note: the “+” and “–” outputs must be connected to the Jumper PC Board
