Program Top Voltage
The top voltage (top speed) is the voltage (speed) at full throttle. The
PRODIGY DCC top end voltage is set for maximum output. If you are
running a switcher, you may want the top end voltage to be less than full
output for more realistic performance at top throttle setting.
To program the top voltage, adjust the throttle for the top voltage setting
and then press the
Program Top Volt button.
Top voltage is a unique programming feature that we
added into the PRODIGY DCC System. Other
manufacturer’s decoders may not be able to use it. The
early MRC decoders AD305, AD310, AD320 and AD330 do
not have this function. All our new decoders such as
AD315 and AD350 will support this feature.
Program Momentum
Momentum simulates the drag of a heavy train as it starts and stops.
Real trains do not jack rabbit start and stop on a dime. You can program
in the amount of momentum you want for the train at hand.
To program momentum, adjust the throttle for momentum setting and
then press the
Program Momentum button. The higher you set on the
throttle dial the more momentum you add.
Program Reverse Polarity
Decoders are programmed with normal direction setting, i.e. it runs
forward when you press the forward direction button. But for multi-lash
up locos, operating back to back, one loco has to be programmed with
reverse polarity.
To program reverse polarity, press the
Reverse Polarity button.
To program the loco back to normal direction setting, just
reprogram its
address. Programming reverse polarity twice will not give you normal
direction setting.
Program Analog Enable
This feature allows the decoder equipped loco to be programmed to run
on a standard analog (DC) layout. When you reprogram a loco with its
address, it disables the analog running ability.
To program analog enable, press the program
Analog Enable button.
NOTE: Program Analog Enable will also program the loco with factory
set direction setting.
Program Loco Address
The address is the number assigned to a decoder to identify the de-
coder. All decoders are programmed with address #3 as the factory
default. You can change the address any time by programming.
To program a decoder, select the loco you wish to program and place it
onto a program track. Then select the program mode by plugging the
handheld into jack #1 and then positioning the
Mode switch to Program.
The Program light on the base unit will light indicating you are in the
program mode.
To program the address, select the address you want to assign the loco
by rotating the dial, and then press the
Program Address button. Please
wait 5 seconds for completion.
Example: How to program decoder with address #2
1. Put loco on program track.
2. You must have the handheld plugged into Jack #1
and the Mode switch positioned on the base unit to
Program. Program LED will light.
3. Turn the address selector dial to #2 and switch the
address bank selector to 1-16.
4. Press Program Address button. Loco will jerk
slightly. Wait 5 seconds for completion.
You’ve just programmed the loco with address #2. It’s
that easy. Now position the
Mode switch on the base
unit to Run. You should be able to operate the loco with
address #2.
Helpful hint: Make a chart indicating the road
names, road numbers and assigned address num-
bers for your locos and keep this chart near your
PRODIGY DCC system for reference.
Program Start Voltage
This is the voltage required to start the locomotive’s motor and overcome
its weight and friction to make it begin to move. You can program your
locomotive with a start voltage so that it will begin to move as soon as
the throttle kicks in.
To program start voltage, adjust the throttle for start voltage setting and
then press the
Program Start Volt button.
