Changing the Decoder Address
The first CV most people change is the decoder address. This allows you to inde
-
pendently control each loco with a unique address. Digitrax decoders are shipped
with CV01 (AD2), the two digit address, set to 03. Following is a brief description
of how to change the decoder address with a Digitrax DT4XX series throttle. See
your Starter Set Manual for complete programming instructions.
1. Place the loco on the
programming track not to exceed 16V
. Go into
Program Mode on your system. On DT4XX throttle press
PROG
.
2. Choose AD2 for 2 digit addressing or AD4 for 4 digit addressing.
3. Choose the address you want to set up for the decoder.
4. Complete address programming by pressing
ENTER
.
Note:
CV29 must also be programmed to enable 4 digit addressing, this is done
automatically by the DT4XX throttles. See your Digitrax Decoder Manual or the
Digitrax Toolbox App for how to set up CV29.
Digitrax LocoMotion
®
System
Your locomotives look like the real thing, now you can make them run like the
real thing, too. Digitrax decoders incorporate torque compensation for smooth
as silk operation. You can also program CVs that control momentum, 3 step and
128 step speed tables, switching speed, normal direction of travel, scalable speed
stabilization and more to take full advantage of the Digitrax LocoMotion System.
Momentum-CV03 & CV04
Momentum is part of the LocoMotion System. Acceleration is controlled by CV03
and deceleration by CV04. Both come from the factory set to 000. A range of 000
to 031 is available for both accel and decel. Try CV03:003 and CV04:000 as a
starting point for experimenting with momentum.
Speed Tables-How the Loco Responds to the Throttle
With Digitrax LocoMotion, there are two types of speed tables: 3 Step Tables and
High Resolution 28 Step Tables. Please see your Decoder Manual for a discussion
of the 28 Step Tables. The 3 Step Tables are set up by programming 3 CVs: Start
Voltage (CV02), Mid point Voltage (CV06) and Max Voltage (CV05). These values
are set at 000 at the factory. All have a range of values from 000 to 255. We rec
-
ommend the following CV values as a starting point for experimenting with speed
tables.
