Installation Instructions
1.
Carefully remove the locomotive shell.
(Figure 1)
Note the orientation to
the frame for correct re-installation.
Arrange internal wires to expose the
jumper board in the locomotive.
2.
Remove the jumper board from the
locomotive’s 21MTC pins.
(Figure
2)
The jumper board allows the loco
to operate on a standard DC track or
in analog mode on a DCC track.
If
the loco also has a 8pin NMRA
socket, any jumpers should also
be removed.
3.
Insert the 21MTC socket onto the ex
-
posed pins. The black socket and the
decoder text should be facing up. The
socket is indexed so it will only fit on
in one configuration.
(Figure 3)
Seat
the decoder firmly on the pins.
4.
Replace the loco shell on the frame.
The loco is now ready to run on your
DCC system using the factory set
address 03. See next page for cus-
tomizing some of the functions of the
DH126MT decoder.
