1. Carefully remove the locomotive’s shell from the frame. Notice the orienta-
tion of the shell to the frame so that you can reinstall correctly.
2. Remove the 6 pin analog shorting plug and in its place insert the DZ125IN
decoder with the correct pin-1 orientation. The DZ125IN has 6 pins that
insert directly into the 6 pin socket (NEM 651 type) on the locomotive’s
PCB. The DZ125’s small size allows the decoder to be easily installed in a
variety of European locomotives. For the Kato EMD Class 66 example, the
DZ125IN should be inserted in the socket as shown in Figure 2.

lights work in both directions
4. Reinstall the locomotive’s shell , install is complete!
For proper installation orientation in Bachmann Farish Jubilee, the Dapol
Hymek and the Trix v160 N scale examples, please refer to page 9 in
this guide. For other N scale locomotives be sure to identify the correct pin-
1 location of the locomotive socket from the manufacturer’s instructions.

DZ125IN is factory default programmed to address 03. You can easily cus-
tomize the address and other features. See section “Customizing Your
Decoder” that
Installation Notes:
1. Do not exceed the decoder’s 500mA total function output rating.
2. We recommend that the Blue wire, also called +Common or Lamp
Common, be connected as shown. If you wish to omit the Blue wire in your
installation, consult the Digitrax Decoder Manual for more information.
3. The head lamp should be hooked up using the Blue/+Common wire for
optimal Digitrax transponding operation.
4. To use a function output with an inductive (coil) type load, see the Digitrax
Decoder Manual for more information to avoid damage to the decoder.
5. See the Digitrax Decoder Manual for full details of wiring 12-16V lamps,
1.5V lamps, and LEDs. Lamps that draw more than 80 mA when running
require a 22 ohm 1/4 watt resistor in series with the directional light func-
tion lead to protect the decoder.
6. Some locomotives employ filter capacitors for RFI suppression in the loco-
motive wiring. These may cause problems with Supersonic decoders and
non-decoder analog operation on DCC. This capacitor should be removed
for safe operation.

Your Digitrax decoder is ready to run and will operate using address 03 with no
additional programming. For a more prototypical railroading experience, your
decoder can be customized for your specific locomotive by programming some
of the Configuration Variables, or CVs, available. See the Digitrax Decoder
Manual or the Digitrax web site for more information.

independently 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 DT series
throttle. See your Starter Set Manual for complete programming instructions.
1 Place the loco on the programming track. Go into Program Mode on your
system. On DT400 press PROG. On DT300, DT100 & DT200 press
RUN/STOP & FN/F0.
2. Choose AD2 for 2 digit addressing or AD4 for 4 digit addressing (DT300 &
DT400). (Ad for DT100 & DT200, see your Starter Set manual for 4 digit
instructions).
3. Use your throttle to choose the address you want to set up for the decoder.
4. Complete address programming. On DT400 press ENTER. On DT300,
DT100 & DT200 press SEL.
Note: CV29 must also be programmed to enable 4 digit addressing, this is
done automatically by the DT300 & DT400 but not on earlier throttles.

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 and more
to take full advantage of the Digitrax LocoMotion System.
M
Mo om me en nt tu um m- -C CV V0 03 3& &C CV V0 04 4
Momentum is part of the LocoMotion System. Acceleration is controlled by
CV03 and deceleration by CV04. Both come from the factory set to 000/x00. A
range of 000/x00 to 031/x1F is available for both accel and decel. We recom-
mend that you try CV03:003/x03 and CV04:000/x00 as a starting point for
experimenting with momentum.

With Digitrax LocoMotion, there are two types of speed tables: 3 Step Tables
and High Resolution 28 Step Tables. Please see your Digitrax Decoder Manual
for a discussion of the 28 Step Tables. The 3 Step Tables are set up by program-
ming 3 CVs: Start Voltage (CV02), Mid point Voltage (CV06) and Max Voltage
(CV05). These values are set at 000/x00 at the factory. All have a range of val-
ues from 000/x00 to 255/xFF. We recommend the following CV values as a
starting point for experimenting with speed tables.

Switching speed is controlled by CV54. The factory setting is 000/x00 for
OFF. To turn on the switching speed feature, program CV54 to a value of
001/x01. When this feature is on, use F6 to activate and deactivate switching
speed. When switching speed is ON and F6 is ON, the switching speed feature
is on. With the feature ON, the throttle’s target speed is effectively reduced by
about 50% and the effects of accel and decel programmed into the decoder are
reduced by 1/4. This is useful for yard switching operations.
Normal Direction of Travel is controlled by CV29. See your decoder manual
for additional information on the settings for CV29.
This decoder supports Scaleable Speed Stabilization (Back EMF)

The factory settings in the decoder provide silent, smooth operation of your
locomotive under most conditions. For more information about these settings,
please see the Digitrax Decoder Manual or our website.

Digitrax Transponding is controlled by CV61. The initial factory set value is
000/x00 for OFF. To turn ON transponding, program CV61 to a value of
002/x02. This allows you to use Digitrax transponding to keep track of your
rolling stock. When transponding is enabled, the front light of the locomotive
will flicker slightly to indicate transponding signal is being communicated. For
optimal transponding operation, we recommend that you hook up the forward
and rear lights as shown in the wiring diagram (Figure 1).

Decoder reset lets you reset all CV values to the initial factory settings. To
reset all CV values, program CV08 to a value of 008/x08. You also have the
option of resetting all values except the 28 speed step tables. To do this, pro-
gram CV08 to a value of 009/x09.

The DZ125IN is set up at the factory to control two function outputs. The
DZ125IN is configured to control the forward and reverse lights on the loco-
motive through the white lead and yellow lead using Function 0 (F0F-forward
and F0R-reverse) for directional lighting. Both function outputs can be easily
set up with Digitrax FX3lighting effects or as standard on/off functions with
the following operational qualifiers:
1. Forward or Reverse direction of travel, or
2. Whether F0 is on or off, or
3. Both direction of travel and whether F0 is on or off, or
4. Whether the locomotive is stopped or moving.
M
Ma as st te er rL Li ig gh ht tS Sw wi it tc ch h
Each of the function outputs can be programmed to turn on and off with the F0
ON/OFF key on your throttle, creating a Master Light Switch. The CV
values for creating this effect are listed in the Digitrax Decoder Manual in the
section: Setting Up FX & FX3Effects on Function Outputs.
