M.T.H. HO F-3 Diesel Engine

To install your DCC decoder:
Step 1:
Remove the engine's body. (See pages 6&7)
Step 2:
- Number Board
- Alternate Lighting Supply
- NMRA Header (both jumpers)
Step 3:
Connect your DCC decoder to the 8-pin NMRA header on your MTH
engine board. Follow your DCC decoder's manufacturer's instructions carefully
NOTE – If your DCC decoder has the extra F – Functions (and wires)
available you can connect the DCC decoder board to the 3 tabs at the end of
the board to control Ditch lights and Number Board lights
If your DCC decoder has only a headlight and a taillight available and you want
to keep your number board lights active, leave the pad jumpers installed for
Number Board on your MTH board. The tabs on the end of the MTH board are
available for you to wire your DCC Decoder’s function control lines to them to
allow control of the Number Board lights. For example, if you want your DCC
Decoder to control the Number Board lights and you have the function control
line to do so, remove the Number Board pad jumper then wire the control line
from your DCC Decoder to the NUM pad on the MTH board.
To mount your DCC Decoder to the MTH board it is recommended that you use
double-sided tape and ensure your DCC decoder board doesn't touch your MTH
board (keep the two boards insulated from one another). There is quite a bit of
room available inside your model so for most DCC decoders you will find it easy
to mount them
Step 4:
If you are connecting the extra lighting function wires from the note
above then simply slide the plastic wire clip off the tab on the MTH board and
insert the wire then slide the clip back on. This provides a secure, yet, quick and
easy way to connect the added function wires from your DCC decoder using the
existing LED's on your MTH engine.
