Locomotive decoder
7
Five wires connect the headlights and functions to the decoder:
•
White wire (Pin #6) to the forward headlight or the function controlled
by Output A. If the bulb is isolated, connect the blue wire (Pin #7) to
the other terminal.
•
Yellow wire (Pin #2) to the rear headlight or the function controlled by
Output B. If the bulb or function is isolated, then connect the blue wire
(Pin #7) to the other terminal.
•
Green wire (Pin #3) to function controlled by Output C. If the bulb is
isolated, connect the blue wire (Pin #7) to the other terminal.
•
Violet wire to function controlled by Output D. If the bulb is isolated,
connect the blue wire (Pin #7) to the other terminal.
•
Brown wire to function controlled by Output E. If the bulb is isolated,
connect the blue wire (Pin #7) to the other terminal.
Place the locomotive (without its shell) on the programming track and read
back the locomotive's address from the decoder. If the decoder is properly
installed, you will be able to read back the factory pre-set address 03.
Configuring the Decoder
The locomotive address, acceleration and deceleration delay, and all
other features of the locomotive decoder can be changed as often as
desired by reprogramming the decoder. The features are "stored"
permanently in special locations even when the operational voltage is
switched off. These locations are called "configuration variables" or simply
"CV". The values are configured electronically, which means that it is not
necessary to open the locomotive again after the decoder has been
installed.
You can alter the content of CVs both through "Programming in
operational mode (PoM)" or "Programming on the programming track".
For detailed instructions on how to program using the above-mentioned
devices, please refer to the operating manuals which accompany those
devices.
The decoder is programmed from the factory for operation with address 3
and 28 speed steps. The decoder can be used with these basic
configurations immediately after purchase. All configurations can, of
course, be changed.
Resetting the decoder to Factory Defaults
If you wish to reset all the decoder CVs to its factory setting, enter value 8
or 33 in CV8.
Please note: Some CVs (such as CV29) have specific meanings for each
bit. The bit assignments in this table use a bit numbering scheme of 1-8
The bit numbers in
()
within these tables contain the bit numbers if you
count from 0-7.
