10.4 Troubleshooting Function Operation
If the function you want to operate does not respond, check the following:
1. Is Track Status on? If not press the Power/Back Key to turn it on.
2. Did you select the correct loco? If not, select it now.
3. Is the function you want to use installed in the loco? If not, you may need to
install it. Most new locos have a head lamp/backup lamp installed, but most
do not have any additional lights or sounds installed.
4. Change the position of the Direction Control Lever and see if the lamp
comes on in the other direction. If the normal direction of travel feature in
the decoder loco is set for the opposite of what you were expecting, you
will see the head lamp operating in what you expected to be the reverse
direction and vice versa for the back up lamp. See your Decoder Manual for
information about how to change the Normal Direction of Travel (NDOT).
11.0 Programming & Reading Your Digitrax Decoders
Your DCC Decoders have many dierent conguration variables (CVs for
short) that let you set up a dierent set of characteristics for each decoder
installed in a locomotive. When you want to change a loco’s address, set up
how its lights work, change its momentum characteristics, etc. you will pro-
gram new CV values into the appropriate CVs to set it up just the way you
want.
Each CV controls a characteristic of the decoder. See your Decoder Manual for
a list of the most commonly used CVs and their meanings. A Digitrax Decoder
Manual is included as a part of your Zephyr Express system. Each decoder
comes pre-programmed with factory settings that will let you run it right away.
If you are using non-Digitrax decoders or sound decoders, please consult the
manual provided by the manufacturer for how CV’s are used and program-
ming instructions.
The factory set address for all Digitrax decoders is “03”. This is the rst CV
you will want to change because it is not very useful to have all of your locos
respond to the same address. The DCS52 has a Quick Decoder Setup that
makes it easy to setup the most common CVs including addresses and CV29
values.
Decoders are programmed when the command station sends programming
information to them through the rails. Your DCS52 supports two types of pro-
gramming:
Service Mode Programming is done on an electrically isolated programming
track. Using this mode, the command station broadcasts programming infor-
mation to all decoders on the program track. Because this is a broadcast mode,
you must isolate the decoder you want to program from the others on the lay-
out. You do this by using a separate programming track that is connected to the
command station for programming but not powered for operation of the loco-
motive. This mode works with all DCC decoders. This is the most commonly
used programming method.
