Congratulations on your purchase of a igitrax Super Chief Xtra Complete
Train Control Set!
The design of the igitrax Complete Train Control system lets you operate
your layout the way you want to. With LocoNet you simply connect system
components to build the layout control system that you’ve always wanted! The
igitrax system reduces and simplifies layout wiring for new layouts. If you
already have a layout, you probably won’t need to rewire to install igitrax.
Your Super Chief Xtra Starter Set has several components:
•DCS100 is your system’s command station. It generates the
information packets that tell the decoders what to do.
•DCS100 is also a booster. Boosters receive signals from the
command station, amplify them and put them on the track along
with the power from the power supply to run the locomotives.
You can have several boosters on your layout to provide addition-
al power to run more locos.
• The DT402 or the DT402D is the throttle that comes with your
Super Chief Xtra Starter Set. Throttles are the handhelds you use
to tell the command station what you want the decoders to do.
You will probably have several throttles on your layout if you
have more than one person running trains at a time.
•AUP5 Universal Panel for memory walkaround operation or a
UR92 uplex Radio Transceiver for duplex radio or IR operation.
•LT1 LocoNet and ecoder Tester.
• A 2’ LocoNet Cable so you can get started right away.
In addition to your Super Chief Xtra you’ll need:
• A power supply (you many be able to use one you already own)
• One or more mobile decoders for your locomotives.
This manual contains information about running your layout with infrared
and/or uplex Radio operation. Information about simplex radio operation is
included for your convenience even though your Super Chief Xtra Set is not
available with this option.
There are many different combinations of igitrax components that can be
used to set up a layout control system that is right for you. You can combine
igitrax products with compatible decoders, boosters and computer software
made by other companies that build compatible equipment.
Your success with & enjoyment of our products are very important to us. After
all, this is a hobby and it is FUN!!! Please read this manual carefully before
installing your system. We have included lots of hints and operating ideas
based on our experience. If you have questions not covered by this manual
please contact your dealer or visit our web site at www.digitrax.com where the
igitrax online Tech Support epot is always open!

These instructions will get you up and running in just a few minutes! A full
description of all controls and technical reference information are included later
in this manual. This section assumes that you are using a new set straight out
of the box. If your set is duplex equipped, we recommend that you follow this
quick start guide without using duplex radio to learn the basics. When you are
successfully running your duplex throttle tethered to the system, then continue
with the Quick Start uplex section that follows to learn how to operate in the

The UR92 uplex Radio Transceiver/IR Receiver is simple to install and begin
using on your layout.
1. In most cases a UR92 should be situated near the physical center of your
layout. One UR92 will cover approximately a circle of 300 feet across.
Some layouts may require additional UR92s for adequate signal coverage.
2. Connect the PS14 C power supply to the UR92 via the C power jack on
the side of the UR92. Plug the PS14 power supply into a 110V outlet.
The green and red LE s should blink and the red LE should stay on.
3. Connect the UR92 to LocoNet “B” jack of your CS100 using one of the
RJ12 jacks at the rear of the UR92. The red LE will go off and the
GREEN “RA IO” LE will wink at a 2-second interval to indicate that it
is configured for duplex operation.
4. If your layout has UR91s and or UR90s installed, re-set the LocoNet I by
plugging in any T402 throttle while holding down the "- Key.
Release the "- Key. Use the R throttle knob to set the LocoNet I (00-
07) you want to use and press Enter to complete LocoNet I set up. As
simplex and infrared throttles plug in to LocoNet, they will log on to the
LocoNet I automatically and all three technologies will work together
See Section 20 for additional information on UR92 setup and
installation.

That is all that is required for UR92 installation! You are now ready to join
a uplex Group with your T402 uplex Throttle! See UR92 installation

The following ‘plug-in’ method of joining a UR92 uplex Group is the most
convenient and will always work to join any uplex throttle to a particular
UR92 Group. You may also join in wireless mode! See Section 14.4 for
instructions on tetherless operation of the DT402D.
1. Connect the T402 uplex Radio Throttle with a known good battery
installed (see following ) to the front RJ12 jack of the UR92 until you see
the throttle initialize.
2. isconnect the T402 from the LocoNet jack. The T402 will briefly
display an 8 character uplex Group name and the Channel number (#11
through #26) being used by the Group. The uplex Group name is not
important at this point, it is simply used by the T402 to join this
uplex group on its particular uplex channel.Note: If your T402 throt-
tle displays “Idle” at this point, simply plug in to LocoNet again and allow
your throttle to re-initialize.
3. The T402 has now joined the uplex Group and can be operated as if it
were plugged in to LocoNet.
4. Use the T402 throttle to select one of the locomotives on your system.
The UR92’s GREEN +"( LE will blink to show that good duplex
messages are being received. If the RF transmissions are not acknowl-
edged by the UR92, the T402 will blink its white “flashlight” LE to
show that there is a duplex radio communication problem. This usually
indicates a range or interference issue. (See the UR92 manual for more
information on troubleshooting duplex radio issues.)
5. T402 s remember the last uplex Group they joined, even if the batter-
ies are removed, so when re-powered they will automatically rejoin this
particular Group if it is within duplex radio range without being plugged in
to the system.
You are now ready to run your trains in uplex Radio mode!

For normal walk around (tethered) operation, the T402 series throttles do not
need a battery. However, when you are unplugged from LocoNet, your throttle
display will go off. We recommend using a battery for T402 operation even
though it is not required. To use your T402/R/ as an infrared or radio throt-
tle, you must install a 9-volt battery. When you install the battery, the throttle
will report the battery voltage then show the last display screen used by the
throttle.
We recommend that you remove the battery from your throttle if it is
unplugged from the system to conserve battery life.
The battery can be stored inside the T402/R/ by removing the battery and
putting it back in the battery compartment with the polarity reversed. See dia-
gram above for proper orientation.
T402 throttles are shipped with the maximum power save option enabled. To
make your batteries last even longer, you may choose to turn off the display
backlight. See Section 10.0 for throttle customization options.

1. Plug the T402 throttle into any throttle jack on a functioning igitrax
LocoNet System or other LocoNet compatible system and you are ready to
get started! See picture in Section 1.0
2. After you plug the T402/ into your LocoNet via any throttle jack, you
will briefly see the T402 splash screen:
This screen shows the throttle type (v): DT402, DT402R or DT402D and
software version number (xx). It is displayed for a few seconds each time
you power on the T402.
3. If you are using a T402 it will then momentarily display the uplex
Group name and duplex radio Channel.
4. Next you will see the power indicator screen.
This screen indicates the power available to the throttle. When you are
plugged in to LocoNet, this value should be between 9 and 15 volts for
proper operation. When you insert a battery or unplug from LocoNet, the
value displayed shows the battery power available. When this number is
less than 6.2 volts it’s time to replace the battery. See Section 3.0 for more
information about installing/replacing the batteries in your DT402.
5. Then you will see a screen similar to the following.
This screen displays current addresses selected on the L and R throttles
along with their current speed and direction. The functions that are turned
ON for the active throttle (the one with the blinking smoke icon) are dis-
played across the top of the display.
6. If you unplug the T402/ from LocoNet the display backlight will go off
while it is unplugged. It will come on again when you plug in to LocoNet
again.

1. The T402 handheld has two knobs called the %Throttle (Left) and the
+Throttle (Right). The throttles are used for speed control, direction
changes, and input of information for operation of your railroad.
2. The row of numbers (0-12) across the top of the display are the functions
being used by the active locomotive throttle.
3 The larger numbers in the middle of the screen indicate the speed of the
locomotives being controlled by the throttles.
4. The numbers at the bottom of the display are the locomotive addresses,
and correspond to the digital decoder that is in each locomotive.
5. There are two locomotives located in the lower corners of the display, one
for the %Throttle and one for the +Throttle. Blinking smoke above the
locomotive indicates which throttle is currently active.
6. There are Direction Indicators (arrow heads) located under each locomotive
which indicate the direction of travel for each locomotive. The arrows
indicate whether the locomotive is moving forward or reverse, not the
direction of travel on the track.
7. The function numbers and text information displayed on the display screen
is for the active throttle. Keypad entries control functions for the active
throttle.
8. The current mode of operation is shown in center of the bottom line of the
display. The normal operating mode is Fn or Function Mode for running
trains. In this mode, the throttle knobs and direction keys control the speed
and direction of the locos. The 2 and 'keys can also be used to

The TRACK POW R indicator on your T402/ and TRACK STATUS indica-
tor on your CS100 command station show whether track power is on or off.
The first time you plug in your throttle, track power will usually be off. Before
you can run trains, you will need to turn on the track power. Look at your
CS100 or T402/ to determine whether the track power is on or off.
When track power is off:
• CS100 TRACK STATUS indicator is off,
• CS100 OFF LIN indicator is on, and
• T402 TRACK POW R Indicator is off (TRACK POW R indicator is
a small dot in the top line on the right side of the display).
When track power is on
• CS100 TRACK STATUS indicator is lit,
• CS100 OFF LIN indicator is off, and
• T402’s TRACK POW R Indicator is on (small dot in the top line on
the right side of the display).

4. Press the )0+ key again to return the T402 to the operating mode.
5. If the TRACK POW R Indicator is blinking and the display shows Trk=Idle
then the layout is frozen in the “IDL ” state and no locomotives will move.
To exit this state simply turn on track power again.
NOTE: To be sure that the signal is available everywhere on the layout, use a
screwdriver blade or a coin across the rails to cause a short circuit. You
will hear the 4 beeps and the CS100 will shut down. Remove the short
and the CS100 will beep once and resume normal operation.
Since the control signal travels with the power on the rails, it is impor-
tant to have power to the track in all locations so that the decoders can
see the signal and respond to your commands.

1. Place an analog locomotive (one without a decoder) on your layout. While
the analog loco is sitting still, you will hear the characteristic “singing”
caused by the CC track signal when it is applied to analog locomotives.
Once the analog loco is moving, this sound will change and be less notice-
able. (Analog locos should not be left sitting on CC powered track for
long periods of time when they are not running.)
2. Check the TRACK POW R Indicator is steady on your T402’s display
and the TRACK STATUS LE on Command Station is lit.
3. Activate the T402’s +Throttle knob by turning it a 1/4 turn in either
direction or by pressing the +Throttle knob once if there is a current loco
address and double click* if S L appears in the +address. If there is a
loco address, the +Loco Smoke will start flashing. If no loco has been
previously selected on this throttle it will flash “S L”.
4. Press the %(( key then 00 on the keypad. You will see a display similar
to this where the Lo and 00 are blinking:
5. Press the %(( key again to select address 00 on the throttle. You can
also press the +Throttle knob once to select the loco address and return to
Fn mode for normal operation.
Note: The 1"- key can be used at any time to return to Fn mode for normal
loco operation.
6. Turn the +Throttle knob clockwise slowly to increase the speed of the ana-
log locomotive. As the speed increases, the locomotive on the track will
begin to move. Your command station’s TRACK STATUS indicator should
change color as you change the speed setting.
7. Press the +/+,+ key on the right side of the T402 or double click
the +Throttle knob to reverse the direction of the analog loco. The

Each decoder has an address. To select a decoder equipped locomotive and run
it on a throttle, you must know its address. igitrax decoders are set up at the
factory with the “default” 03. This means that when you take a igitrax
decoder out of the package and install it in your loco, you can select address 03
on your throttle and run the decoder. The first Configuration Variable (CV)
programmed by most users is the decoder’s address since it is not very useful
to have all of your locos run on address “03.”
If you do not know the address of the decoder equipped locomotive you want
to run, you can simply program the decoder’s address and select it to run using
the new, known address. With the CS100 it is possible to read back the
decoder’s address. See Section 17.5.
1. Place a decoder equipped locomotive on your layout.
2. Check the TRACK POW R indicator is steady on your T402’s display
and the Command Station TRACK STATUS LE is lit.
3. Activate the T402’s %Throttle knob by turning it a 1/4 turn in either
direction or by pressing the %Throttle knob once if there is a current loco
address and double click if S L appears in the %address. If there is a loco
address, the %Loco Smoke will start flashing. If no loco has been previ-
ously selected on this throttle it will flash “S L”.
4. Press the %(( key. The left side of the display will begin flashing. You
will see a display similar to this:
5. Use the numeric keypad to enter 03 or use the +Throttle knob to select
Address “03” in the left side of the display. (The +Throttle knob changes
1s and 10s, the %Throttle knob changes 100s and 1000s.)
6. Press the %(( key again to select address 03 on the throttle. You can
also press the %Throttle knob once to select the loco address and return to
Fn mode for normal operation.

The illustration below shows the display after address “00” is selected on the
+Throttle and address “03” is selected on the %Throttle, We see the TRACK
POW R Indicator On in the top line, the speed bar graphs at 0 speed and the
text area also at 0 speed for both throttles.
7. Turn the %Throttle knob clockwise slowly to increase the speed of the
decoder equipped locomotive. As the value in the left display increases,
the decoder equipped locomotive on the track will begin to move.
8. Press the %+/+, key on the left side of the T402 or double click
the %Throttle knob to reverse the direction of the loco. The %irection
Indicator under the loco icon will toggle between the left and right arrows.
In the case of the decoder equipped loco, the arrow indicates locomotive
direction (forward or reverse), not the direction of travel on the track.
9. Use the +Throttle knob and +/+,+ key to control the analog loco
and the %Throttle knob and %+/+, key to control the decoder

When you are finished with your session, shut down the Super Chief Xtra by
turning off power to the system.
Some users prefer to “dispatch” or release all addresses active in their system
before shutting down. This can prevent unexpected results when you power up
the layout again. The dispatch procedure is covered in detail in Section 11.5.
1. Press the )0+ key followed by the ' key, the TRACK POW R
