1.0 Introduction
Congratulations on your purchase of an Evolution Express system.
The Evolution Express systems use a DCS210+ as the central system
Command Station and Booster and come with a DT602 family throttle. The
DCS210+ includes a USB port for optional connection to a PC. These systems
come with required Universal AC to DC power supplies.
The Evolution Express Duplex system versions have a DT602D duplex throt-
tle and UR93 LocoNet Duplex interface for US customers, and a DT602DE/
UR93E pair for countries requiring additional CE conformance.
To simplify operation the DT602 family of throttles employ a color graphic
LCD screen and a variety of cascading menus, up to six context-related soft
keys and a built in context-related help system that prompts available actions,
or information on the side-scrolling HELP line.
This context HELP system prompting, coupled with a color screen makes the
DT602/ DT602D/ DT602DE easy to use and a powerful layout control throttle.
You will not need to refer to a manual very often!
The DT602 throttle family firmware can be downloaded and updated in the
field using a PC running the free DigiIPL app and connected to the DCS210+
via USB or other working LocoNet connection. The DT602 throttle functions
and screens may change with updates from the Digitrax Web site, so be sure to
check the DT602 product pages to get the latest information and correct .dmf
firmware download files.
The design of the Digitrax Complete Train Control®system lets you operate
your layout the way you choose. With LocoNet®you simply connect system
components to build the layout control system that you’ve always wanted!
The Digitrax system reduces and simplifies layout wiring.
There are many dierent combinations of Digitrax components that can be used
to set up a layout control system that is right for you. You can combine Digitrax
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

2.0 Quick Start Guide
This Quick Start Guide will have you running a train with your Evolution
Express system in about a minute!
Take any analog (address 0000/non-decoder) locomotives o the track before
you begin.
Refer to Figure 1 for the DT602 throttle family layout. Figure 2 shows an
example of the color LCD and the typical HOME screen information display.
1. Power up the DCS210+ with a the PS615 as shown in section 9.0, Figure 3.
2 Plug the DT602 throttle into a LocoNet RJ12 type jack on your DCS210+
using a LocoNet cable provided with the Evolution Express.
3. The DT602 will beep and ash-up a start screen that includes the big text
“Welcome to DT602” and other information, and then log-on to LocoNet and
revert to a normal HOME screen. The STATUS BAR will show the text “LN”
to indicate connection via a LocoNet cable, and green “Trk” letters if the track
power is ON. The DT602 does not need batteries when plugged into LocoNet
4. Press the soft key to select the throttle Left or Right side knob you
wish to use. The display Loco Info Area will indicate the active or focus throt-
tle knob status, and the other throttle knob information will be demoted below
this. Press the; loco key, then the 0 key and then the key again.
5. The throttle display will now show address 0000 in big numbers mid-screen,
and a green Locomotive symbol showing direction, and a current speed indi-
cation above this. The scrolling HELP prompt line above the A/B/C soft keys
provides useful operating hints and information in context as you use the
DT602, or if you get confused as to control actions possible.
6. Press the power key, and above soft key will show Trk_ON or Trk_
OFF indicating the action that will happen when you press soft key down.
Press to toggle, until you see the track status led on the command station is lit,
indicating the track is powered ON.
7. Twist the chosen knob right or left, and the speed % indication will change
and the track status led should change color slightly. Press the direction change
arrow key below the chosen knob to reverse the direction of the Analog loco-
motive selected as address 0000.
8. With these simple steps you have made your rst locomotive address selec-
tion with your DT602 family throttle on the Evolution Express starter set. Place
an analog loco on the connected mainline tracks to now operate it on address
0000.
ENJOY running your trains!

The DT602 has two independent Left and Right throttles. At the HOME screen
use the soft key to choose the focus or display active throttle side you want
to use. Put a locomotive on the tracks that has a known decoder address, sim-
ply restart at step 4 above, and enter the known decoder address to operate that
locomotive. Note that the soft meanings will change as the screens and con-
texts change, and the current key control is indicated by the adjacent screen
text.
The following sections provide additional information beyond the built in
scrolling HELP prompts. Check the Digitrax Web site for the latest DT602
information. The DT602 software can be updated in the eld and so the operat-
ing screens may change slightly over time.
2.1 DT602 LCD screen
The DT602 Display is a 2.4 inch color LCD screen. The screen provides a
variety of information and input prompts to assist in running locomotives and
system setup. This section outlines the Home Operations Screen, other menu
displays will be covered in following sections.
NOTE: The display is best viewed from directly above, viewing the screen at
some angles may distort the perceived screen colors and actions.
2.1.1 Home Operations Screen
Figure 2 shows the primary or HOME operations screen for the DT602. This is
the screen you will see most often when operating trains. The Home Operations

The Loco Info Area is where the current or display focus locomotive
information for the active throttle knob is shown. Changing a knob speed,
direction or the key may change the throttle knob focus side. The
focus loco’s speed is then listed as “sp XX %”. At left is a loco icon with
the current direction indication. Showing forward as “F” and an arrow, or
reverse, shown with or an “R” and arrow. If a focus loco is currently
selected this loco icon will be green with ashing smoke above the smoke-
stack. If no loco is selected the icon will be gray with no smoke. The cur-
rently active address is shown in the large numbers in the center. If a loco
is selected the numbers will be solid black, if no loco is selected the num-
bers will be gray. The focus Loco Info area will show additional informa-
tion during locomotive selection, see section 4.1 for more information on
selecting locomotives.
1. The Status Bar is active for Home screen and will show the status of your
system. There are multiple indicators that appear in the Status Bar. The
“Ln” indicator is solid black when LocoNet is connected OK. The “Trk”
indicator is green when system track power is turned on. In IR or Duplex
mode connection information is shown.
2. The Switch/Fn Info + Area is where turnout or switch information is dis-
played in switch mode. Switch mode is covered in more detail in section
6.0. This area of the screen is also where the complete 29 function state is
displayed when the “Info +” soft key is pressed. Active/ON function num-
bers are blue and inactive/OFF functions are grayed out. For more info on
controlling and managing functions see section 5.0.
3. The Function Bar is where ten active locomotive decoder functions are
shown. The compact function information shown in this bar correlates to
the “Fn+” soft key, pressing the “Fn+” soft key will cycle through control
of higher functions and display them in the Function Bar. For more infor-
mation on using functions see section 5.0.

3.0 Operating on batteries without LocoNet cable
All DT602 models can operate unplugged in IR tetherless (without wires)
mode if they detect Digitrax Infra-Red (IR) capability when rst plugged into
a working LocoNet. The DT602D can additionally operate in wireless Digitrax
Duplex mode if it detects Duplex capability when rst plugged into LocoNet.
To operate a tetherless mode you will need to install three AA size 1.5V batter-
ies in correct orientation in the rear battery compartment. After disconnecting
a battery-powered DT602 from LocoNet, the throttle will enter the tetherless
mode it and the LocoNet system is congured for, IR or Duplex.
The DT602D/DE (Duplex) versions can perform most of its tethered or
plugged-in functions while they are untethered, after initial plug-in to congure
Duplex settings. Duplex throttles will automatically reconnect to the LocoNet
system when disconnected or powered up again untethered.
Duplex mode active will show the Digitrax NetName in the STATUS line
left-side in black text, along with the signal strength bars, Channel number
and Battery level. If a Duplex message fails to get through the white LED
will ash, and if layout Duplex support fails the current NetName display will
change to red text.
3.1 Recharging a Digitrax BP600MH Battery pack
1. Remove the 3 AA batteries from the DT602 rear compartment and plug
the 3 pin plug from an optional BP600MH battery pack into the matching
socket. The yellow lead will be closest to the DT602 bottom edge. Form
the wires to the compartment lower area and then replace the compartment
lid with the battery and wires secure inside.
2. Plug in an external 10V to 18V DC supply (100mA minimum) with a 2mm
center-positive plug into the charging socket at DT602 bottom edge.
3. Press the key until you get the “Charge” text above key, then
press this key again
4. The DT602 will enter charge mode and typically automatically stop after
about 14 hours. When in a charging IDLE mode the key will ash red
about every 3 seconds. Charge time depends on the battery history, like;
residual charge, temperature and tolerances etc.
3.2 Powering a DT602 OFF
To power OFF a DT602 that is untethered before the normal inactivity power
OFF timeout, press the key and then the soft key to power OFF com-
pletely.
In this state the DT602 will draw no battery power, and can be re-powered by
simply pressing the key again. The DT602 will not power down when on
an active LocoNet or plugged into DC for charging.

4.0 How to select Locomotives and run trains
Each decoder receives a unique address. To select a decoder equipped locomo-
tive and run it on your throttle, you must know it’s address. Digitrax decoders
are set up at the factory with the “default” 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.
If you do not know the address of a decoder equipped locomotive, you can pro-
gram a new decoder address and select it to run using this address, or use the
DT602 and system programming track to read back the decoder address. See
Section 7.1 for details on address and CV programming.
4.1 How to select a Locomotive address
1. In order to select a locomotive you need to know it’s address and place it
on powered layout track..
2. Press the key once to enter loco selection mode, the large numbers in
the Loco Info Area will begin to blink alternating black and gray. The soft
keys will also change to give you new choice; “MU”, “Recall” and
“MORE”. Pressing “MORE” will bring up “Disptch” “Stat. Edit” and
“MORE” as soft key choices. Pressing “MORE” again will return to the
previous soft key choices. These soft keys will be covered in the following
sections.
3. Enter the address number of the locomotive you want to select. The text
above the address number will provide you additional information about
the loco address number you are selecting. If it says “free” the locomotive
is available for selection. If it says “busy” the locomotive is in-use on
another throttle, to select it you must complete the Steal process. See sec-
tion 4.6. The second set of numbers, usually “128” species the number of
speed steps associated with the address. See Status Editing, Section 4.7 for
more details.
4. If there is “cn”, “mid’, or “top” the locomotive is part of an MU/consist,
see section 4.8 regarding consisting. Soft key
E
as “Sel Top” will appear
if the address has a link up in an MU. Press this key to nd then select the
TOP loco address to control the whole consist speed and direction.
5. Once you have entered the address, press the key again. The entered
address number will go steady black and you will have control of the loco-
motive. Make sure that Track Power is turned on. The Track Status
Indicator should be lit.
6. Turn the Throttle Knob to now run your Locomotive. Change direction
with the direction key under the speed knob. You can also “double click”
down quickly on the throttle knob to change direction.

4.2 Selecting an Analog or non-decoder locomotive
A locomotive without a DCC decoder is called an Analog locomotive and is
run on address 0000. While an analog locomotive, with no decoder, is sitting
still on your digital layout, you will hear a “singing” sound. 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 running.
As with a regular DC system, only one analog locomotive can be controlled
at a time. If you 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
“0000”.
4.3 Select a prior address using RECALL soft key
In loco selection mode when the key shows “Recall”, pressing this key
will bring up the non-volatile list of the last 10
unique addresses used on this DT602
When in Recall Session Loco List screen, press-
ing a 0-9 numeric key with a 4-digit address to
the right will enter that number as the selection
address For example if you press the 6 key for
the recall screen shown to the right, then the
address 1000 will be entered as the recall selec-
tion address. The selection screen will go back
with this number and pressing will com-
plete the selection of address 1000.
4.4 Releasing an address from a
throttle
When you are nished running a locomotive
address, it is best practice to release it from your throttle, so that it is available
for other throttles to select and run.
1. Use the Throttle Knob to make the locomotive’s speed zero (this option-
al step is strongly recommended as the loco will continue to move after
released if speed is not zero).
2. Press the key to go into locomotive select mode.
3. The address will begin to blink in the display. Press the key, this will
release the address from both the DT602 and the locomotive stack in the
system. The display on your DT602 will show the previously selected
address grayed out.
4. If you press the key again, the DT602 will begin ashing the address
you just released. You can re-select that address by pressing the key or
you can enter a new address number to select.

4.5 How to Dispatch Locomotives
Dispatching is a special feature incorporated in the LocoNet system to meet
the needs of operators that wish to enforce a strict discipline in how operators
gain access to locomotives during an operating session. Dispatching also lets
you run consists with basic throttles that can’t set up their own consists and run
four digit addresses on basic throttles that only have two digit capability. It lets
you have newcomers run trains on the layout without giving them access to the
entire operation.
When you dispatch a locomotive address or consist to your LocoNet system,
you make it available to be acquired by another throttle. Only one address at a
time can be marked as a dispatched address in the system.
To dispatch a locomotive address using a the DT602
1. Press the key to enter address selection, enter the address you want to
dispatch.
2. Press the key marked “MORE” to bring up additional address selec-
tion soft keys. Pressing more will bring up “Disptch”,“Stat.Edit” and
“MORE” as soft key options.
3. Press the key now marked “Disptch” to dispatch the entered Loco
Address.
The dispatched address can be a single locomotive address, either two digit or
four digit, or a consist/MU that was set up by the DT602. The TOP locomotive
in a consist or MU can be dispatched to transfer control of the entire consist to
another throttle.
4.6 How to Steal Locomotives, forcing selection
If you try to select a loco address that is already selected on another throttle the
DT602 will display “adr-busy” in red above the address in the Loco Info area
of the display when the address is entered.
This is a safety interlock to prevent operators from taking control of locos that
are already selected on other throttles. Occasionally it is necessary to override
this interlock to gain control of a loco that is “lost” for whatever reason. This
override is called “stealing a locomotive”. When stealing with the DT602 it
is then possible to have an address selected on more than one throttle on your
system.
To steal an address with the DT602:
1. Press to enter selection mode.
2. Enter the address of the loco you want to steal and press again.
3. A scrolling message will appear in the Scrolling Help Text Area reading
`”Press YES to steal Loco, No to exit” and the lower soft keys will change
to “YES” and “NO” choices.

12
4. To steal the loco address press key marked “YES”, to cancel the
selection press key marked “NO”.
4.7 Status Edit, changing speed step settings
To Change the Speed Step Settings for a Decoder:
1. Select the loco address you want to status
edit.
2. Press once to enter loco selection
mode, the large numbers in the Loco Info
Area will begin to blink black and gray.
The soft keys will also change to give you
the options “MU”, “Recall” and “MORE”.
3. Press the key labeled “MORE”: This
will bring up the additional loco selection
tasks of “Disptch” and “Stat.Edit” above
the A and B Soft Keys.
4. Press the key below “Stat.Edit” text.
The Status Edit Loco# menu will appear
and display the available speed step set-
tings.
5. Press the number on the keypad to select the corresponding speed step
setting. The menu will exit and you will see the corresponding speed selec-
tion in the Additional Loco Selection Info area.
6. Once the speed step setting you want to use is in the display, press the
key to complete the selection and speed step setting change. Once this
change is made, the Digitrax command station will send DCC commands
to the edited decoder in the speed step setting you entered.
4.8 Multiple Unit [MU] or Consist operations
It is not uncommon to see two, three or even four diesel locos pulling in consist
at the front of a train. Sometimes, there is a locomotive added in the middle of
the train or at the end of the train to give “helper service” to the head end loco-
motives. This is called Multiple Unit Operation or MU operation. With DCC,
each locomotive is separately controlled. But in the case of MUing we would
like to have more than one locomotive address controlled by a single throttle to
simplify MU operation.
Your DT602 uses universal consisting to make MU operations simple and easy
to do. This is the most exible and realistic method of MUing available. You
can add any locomotive to your MU, no matter what kind of DCC decoder
is in your loco. You can even add an analog loco to your MU.
You can add a locomotive to an MU in either orientation and in any physical
location in the train. When you send commands to the MU you use the address
of the TOP locomotive to control the entire MU and the command station
handles the rest of the commands to the other locomotives in the MU. As the

address you will use to control the consist is not necessarily the address of the
lead or head end loco, we use the term “TOP” for this special address. The
TOP address can also be the train number.
You will not be able change the speed or direction of any individual loco that
is part of an MU, however you can control individual locomotive functions.
Locomotive speed and direction for all locos in the MU are controlled by the
TOP address
4.9 Adding a Locomotive to an MU
To MU two locomotive addresses together with the DT602:
1. Choose two locos you want to MU together. Place them on the track. Make
sure that both locos that will be part of the MU are running in the same
physical direction. Select and run the rst loco to determine which way it
is headed. Then select the other loco and run it in the same physical direc-
tion. They are now ready to consist.
2. Select the address you want to use to control the MU. This will be the TOP
address. To do this, press enter the address numbers & press again.
3. Press again to re-enter loco selection mode, and the large numbers in
the Loco Info Area will begin to blink black and gray. The soft keys will
also change to give you the options “MU” “Recall” and “MORE”.
4. Press key labeled “Mu”: This will enter MU mode. The display will
now show the TOP address below the blinking loco address number. It will
say “Consist To:” and then your chosen TOP loco’s address. It will also
now show a “MU+” soft key.
5. Use the Keypad to enter the locomotive address you wish to add to the
consist.
6. Press key now labeled “Mu+” to make a consist addition of the newly
selected address.
7. The DT602 will consist the ashing address to the TOP loco, exit MU
mode and the TOP locomotive will remain selected on the throttle
8. To add additional locos to the MU/consist repeat steps 3-6.
If your MU could not be set up the DT602 will display and informational mes-
sage in the Scrolling Help Text line.
This happens when you try to link to an address that is already part of an MU
or link an address that is under the control of another throttle. For example if
you MUed address 14 to the TOP loco 23 and then tried to MU another address
to 14 you would get this error. If you wanted to add another loco to the MU
with 23 as the TOP address, the right way to do it is to add that loco to 23, not
to another address in the MU.

4.10 Removing a Locomotive from an MU
To remove a locomotive address from an MU:
1. Select the locomotive address you want to remove from a consist. To do
this, press and enter the address numbers. The large address numbers
in the Loco Info Area will begin to blink black and gray, and the consist
ag “cn” should show in the Loco Info area indicating this address is in a
consist. The soft keys will also change to give you the options “MU”,
“Recall” and “MORE”& press again.
2. Press the once to enter MU mode, If the ashing address is in a con-
sist the new soft key settings will include an “MU-” choice
3. Press the key labeled “MU-”: This removes the ashing address from
the consist. The DT602 will exit MU mode and the removed locomotive
will now be selected on the throttle.
4.11 MU of mismatched locomotives
If all the locomotives in the MU have performance characteristics that are
closely matched, you can run all the MUed locomotives in e.g. 128 step mode.
If the units are completely mismatched (for example, if you are running two
dierent brands of locos with noticeably dierent characteristics), then we
recommend speed matching the locos by programming the decoder with either
Simple 3 step or Advanced 28 step loadable speed tables (See your Decoder
Manual for more information on these features of your decoder).
4.12 Controlling functions on MU’ed locomotives
Even though an individual locomotive is part of an MU and you can’t control
its individual speed and direction, you can still control its function outputs
independently as follows:
1. Select the loco that is part of an MU which you wish to independently con-
trol functions. To do this, press enter the address numbers & press
again to complete selection of the consisted loco.
2. Now use the numeric keypad to control the consisted loco’s functions like
you would any other loco. The changes will take eect immediately if the
locomotives are moving, otherwise changes will take eect when you rese-
lect the TOP address on the throttle.
3. When you are nished turning functions on or o for the consisted loco,
simply select the TOP address and resume running the MU.
4. Remember, you will not be able change the speed or direction of any indi-
vidual loco that is part of an MU. Locomotive speed and direction for all
locos in the MU are controlled ONLY by the TOP address loco.

5.0 Locomotive Functions
Most DCC decoders have function outputs that you can use to control lamps,
LEDs, sound, smoke generators and other on/o devices installed in your loco-
motives. Most locomotives made today come with a head light and sometimes
with a rear light, too. With DCC, these are controlled by the decoder’s function
outputs. You can also install additional DCC controlled lighting such as cab
lights, Mars lights, ditch lights, rotating beacons and others on your locos. The
addition of these functions can add to the fun and realism of your locomo-
tives. You must have the functions installed and connected to the appropriate
decoder function leads in order to use the following keys.
5.1 Controlling Functions F0-F9
To operate functions F0-F9 on your locomotive:
1. Select the loco you want to control. By default the Home Operations
Screen uses the keypad numbers to operate functions. On DT602 press the
the key until you will see the “Fn+00”over the key. Press the
key to get “Fn Info+” over the key
2. Use the DCS52’s numeric key pad to turn the same number 0-9 functions
on and o. For example, to turn the head light or F0 on, press the 0key.
Press the 0 key again to turn it o. The corresponding function number
will go blue for on and gray for o in the Function Bar area of the dis-
play.
3. .
NOTE: “Fn+00”should be over the key and numbers 0-9 should be
shown in the Function Bar area of the display.
5.1.1 Function 0 (F0) Headlights Forward and Reverse
Press the key to toggle F0 between on and o. Each time the key is
pressed while in function mode, Function 0, also called F0 will change from o
to on or vice-versa. On locos with reversing head lamps and back up lamps, the
head lamp or back up lamp in your loco will come on depending on the direc-
tion of travel of the loco. Function 0 is most often used to turn on/o the head
light/back up light but can be set up for other functions as well (See your
Decoder Manual for more information). It can be used as two functions.
5.1.2 Functions 1,3, 4, 5, 6, 7, 8 & 9
Press the number key on the numeric keypad that corresponds with the function
number you want turn on/o. The function will toggle between on and o each
time you press the number key.
5.1.3 Function 2 (F2) Momentary Operation
Press the 2key on the numeric keypad. The 2key operates Function 2 and
is the preferred function for whistle or horn operation. This key is set up as a
“non-latching key” so that if a horn or whistle sound is installed in the loco, it
will sound for as long as the key is held down. This lets you vary the length of
time that the horn or whistle blows, just like the prototype.

5.2 Functions 10 through 28 (F10 - F28)
From the Home Operations Screen, press the labeled “Fn+00” to cycle
through the functions “Fn+10” and “Fn+20”. When “Fn+10” is displayed over
the soft key the numeric keypad will control functions 10-19. If “Fn+20” is dis-
played the keypad will control functions 20-28. Press the again to return to
“Fn+00” which will allow the keypad to control functions 0-9. In addition to
watching the soft key data the full function number
and status will be displayed in the Function Bar
area of the display.
5.3 Fn Info+ : expanded function status
If you wish to view the status of all 29 functions at
once you can use the “Fn Info+” soft key. From the
Home Operations Screen, press the labeled “Fn
Info+” this will expand the Function Bar area to
show functions 0-28. To collapse this function dis-
play press the then labeled “Fn Info-”.
NOTE: The functions controlled by keypad still
correspond to the status of the key “Fn+00”, “Fn+10”, and “Fn+20”.
5.4 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. Press the direction arrow key, or double press the encoder switch, on the
active throttle 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).

6.0 Switch/Turnout control mode
Switch Mode is most commonly used for sending commands to accessory
decoders to control layout turnouts, and also for changing Option Switches
(OpSw) on other LocoNet devices. Switch commands may also be used for
controlling Digitrax compatible signal units. This section assumes that you
have already installed and programmed turnouts and turnout decoders on your
layout.
To change the position of a turnout:
1. Press the or switch key.
2. The last switch address you selected will be
displayed in the Switch/Info + Area of the
display shown in Figure 2. If 0001 was the last
switch you used and was thrown, the display
“Switch:0001=Thrown” will be shown.
3. Use the numeric keypad to enter the turnout
address for the turnout or switch you want to
change.
4. Press key for “Thrown” action, and the
key for “Closed”, to change the turnout or
switch accessory decoder position.
5. When you have nished your switch operations, press to return HOME
to normal operation mode.
NOTE: The “Closed” or “Thrown” shown in the display may or may not
match the physical position of the turnout selected.
NOTE: When you are in switch control mode, the throttle knob and their
direction keys will continue to drive the loco address running on the throt-
tle, but the numeric keys are used for switch address selection and not
function control.
7.0 Expanded Menu Features
To reduce display clutter the DT602 places expanded
menu choices in a menu system accessed by the
or MENU key. Pressing the key from the HOME
screen will bring up the MAIN Menu A screen with
several numeric key selection choices shown, such
as Decoder programming, Utility and Throttle option
setup, etc.
7.1 Programming Your Decoders
Decoders are programmed when the command
station sends programming information to them
through the rails. Your DT602 supports two types of
programming: Programming on the Mainline and
Service Mode Programming on an electrically isolated separate program-
ming track.

Using Service Mode, the command station broadcasts programming informa-
tion to all decoders on an isolated program track. Because this is a broadcast
mode, you must isolate the decoder you want to program by using a separate
programming track that is connected to the command station for programming
but not powered for operation of the locomotive. This mode works with all
DCC decoders. This is the most commonly used programming method.
Your DCC Decoders have many dierent conguration variables (CVs for
short) that let you set up a dierent 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. Please consult the manual provided by the manufacturer for how CV’s
are used and programming instructions for your decoder model.
7.1.1 Using Quick Decoder Setup
Be sure that only the locomotive you want to program is on the programming
track if you use Direct, Paged or Physical types of Service Mode CV program-
ming.
1. To enter Quick Decoder Setup, press the key. Main Menu A will dis-
play giving you a list of menu options. Select 1-Quick Decoder Setup by
pressing the key on the keypad.
2. This will put you in Quick Decoder Setup. This
uses Direct Programming mode on the program
track. In this mode you can change the loco-
motive address AD2, AD4 and CV29 settings.
3. Once in the Quick decoder setup menu you can
change AD2 and AD4. You must decide what
address you want to use, for addresses 0000-
0127 you will use AD2. For addresses 0128-
9983 you must use AD4.
4. Press the key “READ” to read the current
data from your decoder. This step isn’t required but is useful in conrming
existing decoder settings.
5. To set AD2 press the key on the keypad to highlight the AD2 line.
Press the key “DATA” to modify AD2. Use the keypad to enter the
address you want to use, press key “WRITE” to write the AD2 address
to the decoder. To make changes to AD4 or CV29 press the key
“SELECT” to select additional lines in the Quick Decoder Setup Menu. If
you are done making changes press the key.
6. To set AD4 make sure you are back in select mode ( key will read
“DATA”). Press the key on the keypad to highlight the AD4 line.
Press the “DATA” to select the line. Use the keypad to enter the AD4
address you want to use, press “WRITE” to write the address to the
decoder.

NOTE: “Use AD4” in CV29 must be set to OFF to enable AD2 and must be
set to ON to use AD4. The DT602 will automatically set this value when a
change is made to AD2 or AD4. This option can also be manually set by fol-
lowing the below steps.
7. CV29 can also be setup in the Quick Decoder setup. CV29 also called the
Conguration Register is a special CV that controls a number of character-
istics for your decoder. CV29 controls:
• Normal Direction of Travel (NDOT)
• Speed Step Control: Advanced Mode or Standard Mode
• Analog Mode Conversion
• Speed Tables
• 2 or 4 digit addressing
See your decoder manual for a full listing of these features.
8. CV29 can be changed two ways in the Quick Decoder Setup. When in
Select mode ( key will read “DATA”) simply press the number key
corresponding to the feature you want to toggle o/on. For example press-
ing the key will toggle analog mode conversion o and on. The CV29
Value will automatically be calculated. Once you have all the settings con-
gured the way you want simply press the “WRITE” to write the con-
guration to the decoder.
9. Alternately, if you know the CV29 Value you want to program into the
decoder you can select it and use the keypad to enter the number. CV29
values can be looked up in the Decoder Manual or on www.digitrax.com.
10. To manually enter the CV29 value. Press the key on the keypad to
highlight the CV29 Value line. Press the “DATA” to select the line.
Use the keypad to enter the value you want to use, press “WRITE” to
write the value to the decoder.
11. After values are written to the decoder the text “CV Task Completed OK”
will scroll in the Scrolling Help Text line.
7.2 Read and Write Configuration Variables
There are many dierent CVs that have been dened to control the operating
characteristics of your locomotives. Your decoder manual has a complete list-
ing of CVs that are available in specic decoders, what they do and suggested
values for each CV. Programming these CVs is straightforward:
1. Be sure that only the locomotive you want to program is on the program-
ming track (if using Operations mode CV programming the loco will need
to be on the powered mainline).
2. To enter the CV Programmer, press the key.
3. Main Menu A will display giving you a list of menu options. Select 2- CV
Programmer by pressing the key on the keypad.
4. You will be presented with CV Program Menu A. From this menu use the

keypad to select the method of programming
you wish to use by pressing the correspond-
ing number.
• 1-Po; Ops on Mainline
• 2-Pd; Direct on Prg Trk
• 3-Pg: Paged on Prg Trk
• 4-Ph: Physical on Prg Trk
Note: Direct programming is the Digitrax pre-
ferred method
5. Once you have selected a programming
method, it will be listed above entries for
CV number and CV data. CV number is the
number of the CV you are changing. CV data
is the value you are programming to the CV number.
6. To change the CV number you are editing
press the “CVNUM”, then use the keypad
to enter the CV number you want to change.
7. Once you have the CV number selected press
the “CVDATA”. The soft keys will
change to “WRITE”, “READ”, and “BACK”.
Press the “READ” to read the current
value of the CV number you have selected.
Use the keypad to enter the value you wish to
program to the CV number you have selected.
Press the “WRITE” to save the data
entered. The Scrolling Help Text line will
read “Program Task OK” when it has success-
fully programmed the value.
8. Press “BACK” to exit to the previous menu to select another CV to
change if you wish. If you are done editing CVs press “DONE” to
return to normal operations.
7.2.1 Programming On The Mainline
Operations (OPS) Mode Programming lets you program CVs in DCC loco-
motives equipped with extended packet format decoders while they are running
on the mainline. A typical use for OPS mode programming would be to change
the acceleration rate (CV03) or the deceleration rate (CV04) of your locomo-
tives to simulate the weight and braking capability of the train to compensate
for changing the number of cars or power units on a train.
Your DT602 can use OPS Mode Programming to change the CV value in ANY
CV, including 2 digit and 4 digit addresses, but some decoders may not accept
changing these CVs in Operations mode.
How to use Operations Mode Programming:
1. Make sure the loco you want to program is on the powered up mainline
connected to the Rail A and B terminals of your command station.
