TRACK STATUS Light should slightly change color as you change the
speed setting.
8. Change the Direction Control Lever to &*&' and the loco will move
in the opposite direction.
9. Change the Direction Control Lever to the & position and the loco
will slow down and stop. Move the Direction Control Lever to #&+&
or &*&' and the loco will move again.
10.Turn the Throttle Knob to '(#$ and the loco will stop moving.
11. If you have a headlight installed in your loco, it will be on and stay on
because with DCC there is constant power to the track.
A locomotive without a DCC decoder is called an analog locomotive. While
an analog locomotive, without a decoder, is sitting still on your digital layout,
you will hear a “singing” sound. This is caused by the DCC track signal when
it is applied to an analog locomotive. Once the analog locomotive is moving,
this sound will change and be less noticeable. To avoid heat build up in your
locos without decoders, Digitrax recommends that analog locos NOT be left
sitting on DCC powered track for long periods of time when they are not run-
ning.
Address 00 is reserved for running an analog locomotive. Your analog locomo-
tives will not run with any other address. As with a regular DC system, only
one analog locomotive can be controlled at a time. If you try to run more than
one analog locomotive at the same time on the layout all of the analog locos
will respond to the commands sent to address 00. By adding DCC decoders to
your locomotives and additional throttles to your system, you can individually
control up to 20 locomotives at the same time with your Zephyr Xtra Set.

1. Each DCC decoder can be assigned a unique DCC decoder address that is
used by the system to send commands to that decoder. The address is a
numeric value remembered by the decoder in the loco until you change it.
2. You program each of your locomotives with its own unique address so that
you can run them independently.
3. To select a DCC locomotive and run it, you must know its address.
4. Digitrax decoders are set up at the factory with address 03. This means that
when you take a Digitrax decoder out of the package and install it in your
loco, you can select address 03 on your throttle and run the decoder. You
can easily change this address by following the instructions in Section 16.2.
To make the examples easier to follow, let’s leave everything at the factory
settings for now.
