Select Locomotive to Drive

The DT100R must be connected to LocoNet to perform this function.

Turn desired throttle knob at least 1/8 turn in either direction until the display shows SE:L-. If SE:L- does not appear, the throttle knob may already be assigned to a locomotive. The first time a locomotive is programmed to a throttle on the system it is set to the throttle knob at speed 0, forward direction and all functions off. The only way to control consisted or MU'd locomotives is to select the address of the TOP of the consist.

If you try to access a locomotive address that is active on another throttle, when you press to set the address, the display will change back to SE:L- and the throttle direction indicator will not light.

To select a 2-Digit Short Address, press the button — the display shows 00:03 with the "00" flashing. Turn either throttle knob until the desired locomotive's address appears on the display. You may also use the or buttons to browse to the desired address. Press to set this address active.

To select a 4-Digit Long Address, press and hold the button then turn one of the throttle knobs. The DT100R enters the 4-digit long address range, and the RED EXP indicator lights. Browse for the 4-digit address you wish to select (left throttle knob changes in hundreds, right knob in ones). Press to set this address active.

Notes
If during the address select process there is no input for the 6 second time-out period, the DT100R will abort the selection process and restore back to LOCO mode.

If the right hand side of the display shows FF during address selection it means the Command Station has reached the limit of its internal slot memory. If this occurs you can free up some slots by making sure any locomotives not being used are not selected on any throttle. Depending on the Command Station (DCS100, DCS200) it may be possible to increase the capacity of slot memory. Refer to the Digitrax System manual.

Forced Selection — Stealing a Locomotive

Except where instructed below, the DT100R must be connected to LocoNet to perform this function. The throttle must have a good 9 volt battery installed.

Normally a locomotive cannot be selected if it is already assigned to a throttle. It is possible to override this interlock and force the DT100R to select an in-use locomotive. To "steal" a locomotive, do the following:

• In the same way you would select a locomotive to drive, browse to the address of the locomotive you want to steal. With a 2-digit address the right side of the LCD display should typically show 3x. With a 4-digit address the locomotive status will flash up St:3y.

• Before you timeout from browse mode and while you still have the desired locomotive showing in the display press the button. (If the locomotive is not available for any reason, the display will show SE:L-.)

• Disconnect the DT100R from LocoNet. The display should immediately go to idle.

• Press and hold the direction arrow button for the throttle side (either or ) you used above and plug the DT100R back into LocoNet. After the DT100R beeps release the direction button and the throttle being used should be logged onto the stolen locomotive address.

If the locomotive is active on two throttles, both throttles can update speed and direction information for the address.

Controlling Lights and Functions

Press the button once to enter the Light/Function control mode for the "display active" throttle. The display will show Fn:oo with the n flashing to indicate that the function number of the function you wish to change needs to be selected.

Use one of the five BLUE buttons to choose the function you want to change. The button will now select and change the Light or F0 function. Each time the button is pressed while in the Fn:oo mode, the Light/F0 will change from OFF to ON and vice-versa. The display will show F0:on (Function 0:on) for light ON and F0:of (Function 0:off) for light OFF. The operation is the same for the other functions F1, F2, F3 and F4.

To access functions F5 through F8, press and hold the button while pressing the BLUE F5, F6, F7 or F8 buttons to toggle between on and off for the function chosen.

You can change any or all of the functions F0 – F8 while you are in the Fn:oo mode.

There are three options to return to LOCO mode:

• Adjust either throttle knob

• Press the or buttons, or

• Wait for the 6 second no-input time-out to elapse.

Notes
F2 is a non-latching function, which aids in controlling sound features such as a horn or whistle. The function operates only when F2 is held down in the Fn:oo mode.

Even though a locomotive is part of a consist, its functions can still be accessed independently. Select the desired locomotive address in the normal manner. After the button is pressed the display will show cn (aa:cn for 2-digit address; -cn- for 4-digit address). Press the button and proceed with the normal function controls described above.

Set Up Multiple Unit Operation

The DT100R must be connected to LocoNet to perform this function.

The TOP locomotive is the locomotive on the DT100R right throttle, and is the controlling locomotive. Other locomotives in the consist are added from the left throttle to the TOP locomotive, each in turn.

Set the address and relative direction of the next locomotive using the left throttle, as described in "Select Locomotive to Drive", and place the locomotive in physical position in the MU consist.

Press the button twice to cycle the DT100R through SWITCH mode to MU mode. The MU LED indicator lights.

Press the button to add the locomotive to the TOP locomotive.

Notes
It is possible to add a consist to another consist — i.e. nested consists. The TOP of the top consist should be on the right throttle knob. The TOP of the consist to be added should be on the left throttle knob. Add the left consist to the right consist as described above. The overall consist is controlled by the right throttle knob. It can then be released and selected to run from either throttle knob or on another throttle or dispatched to the system.

Remove a Locomotive from a MU Consist

The DT100R must be connected to LocoNet to perform this function.

Select locomotive to be released on the Left throttle. The display will show cn for the locomotive speed.

Press the button twice to get to the MU mode.

Press the button to unlink the locomotive. The unlink is complete, and the left throttle becomes active with the locomotive just unlinked. The unlinked locomotive is broken out of the consist at the current speed and direction it was going in the consist.

Notes
To unlink an entire nested consist you must first dial up the TOP of the nested consist onto the left throttle knob. Then unlink it as described above.

Dispatch a Locomotive

Follow the procedure above to select the desired locomotive to drive.

Press to enter Address Select on the active throttle.

Press the button once to dispatch the locomotive or MU consist. The locomotive or consist is dispatched in its current state — moving, stopped, etc.

Locomotive Speed and Direction Control

Locomotive Speed Control
Turn the throttle knob that is set to the locomotive whose speed is to be changed. If not already active in the display, the throttle will become "display active" and the display will show the address and current speed. As well as by turning the throttle knob, speed can be changed using the and buttons.

With a 2-digit address the address is shown on the left side of the display with the current speed on the right side, separated by a :. When a 4-digit address is changed the new speed xx will flash up on the display as SP:xx and the display will return to the steady 4-digit address with no colon, and with the LOCO flag on.

The only way to change the speed of consisted or MU'd locomotives is to select the address of the TOP of the consist. When a consisted or MU'ed address other than the top address is selected the display will turn to aa:cn if a 2-digit address aa or to -cn- followed by the 4 digit address if a 4-digit address. This indicates the speed of this address cannot be changed since it is in a consist. Functions such as lights can be modified for such an address.

Locomotive Direction Control
To change a locomotive's direction press the button for the address set to the Right Throttle Knob or the button for the address set to the Left Throttle Knob. The direction indicator beside the throttle knob will change color (to RED for reverse or GREEN for forward). The throttle is/becomes display active.

Changing direction of a moving locomotive will cause it to slow down to 0 speed and then speed up to the commanded speed according to the decoder's programmed deceleration and acceleration characteristics. (Zero deceleration and acceleration settings will result in instant reversal.)

Status Edit a Decoder

The DT100R must be connected to LocoNet to perform this function.

Status editing of a decoder is required when the decoder is not able to operate under the Command Station's normal configuration. To status edit a decoder you must do so after dialing the desired address and before pressing to set the decoder to the throttle.

Press and turn either throttle knob until the desired address appears on the display. For a 2-digit Short Address, the decoder status will display in the right side of the display aa:xy where x and y are the two digits of the status code. For a 4-digit Long Address or Aliased 4-digit Address the data will be displayed in 2 screens — the first screen is the 4-digit long address for about 1 second, then St:xy which means Status Code = xy.

Press the button and the status code xy will begin to flash.

Use either throttle knob to change the status value. This value will be displayed in the right hand side (2-digit) of the display or on the second screen (4-digit).

When the desired status code is displayed press to change the status code and set it to the display active throttle.

A consisted locomotive address cannot have its status edited. The locomotive must be unlinked from the consist.

Notes
You cannot change the value of the x which is set by the system. The values for y are as follows:

Entering Programming Mode

Press the and buttons together, until the Programming indicator PROG LED glows GREEN.

Be sure the locomotive to be programmed is on the programming track.

Note that CV01, the locomotive address CV for 2-digit addressing, displays as Ad rather than 01.

Exiting Programming Mode

To return to LOCO mode when finished programming, press the and buttons simultaneously. The PROG LED will go out.

Programming the Decoder

Turn the Left Hand Throttle Knob "L" until the Configuration Variable (CV) number to be changed is displayed in the left hand side of the LCD screen. When a CV is first accessed, it will display 2 dashes (- -) in the right side of the LCD to signify that the CV contents are unknown. (Note: CV01 will display as "Ad" on the left side of the display.)

Press the button to read the current value programmed for this decoder. As the Command Station is scanning or reading the decoder the left most digit will move in a "pretzel" formation to show activity. When a data value is successfully read, it will display flashing in the two right hand digits.

A read failure will result in one of the following messages:

Entering Programming Mode

Select the locomotive address you wish to program and set it to either throttle knob. Be sure the address to be programmed is the "display active" throttle when you perform the next step.

Press the and buttons together, until the Programming indicator PROG LED glows GREEN. Then press the button to scroll from Paged, Physical or Direct programming modes to Operations mode. The LCD display will show OPS.

Use the left throttle know "L" to select the CV to be modified. Use the right throttle knob "R" to select the value to be programmed to the CV. Press either the or buttons to program the selected value to the selected CV.

If you get a bUSY message in response to a or button press, the system is temporarily busy. Try again until you get a Good response.

Exiting Programming Mode

To return to LOCO mode when finished programming, press the and buttons simultaneously. The PROG LED will go out.

Changing Decoder Address

Operations Mode programming cannot be used to make changes to CV01 or the 2-digit short address of any locomotive at any time. An attempt to program a 2-digit address will result in a FAIL message when writing the address is attempted.

Operations Mode programming cannot be used to make changes to a 4-digit long address of any locomotive that was addressed by its 4-digit long address when programming mode was entered. An attempt to program such a 4-digit address will result in a FAIL message when writing the address is attempted.

Operation Mode can be used to write a new 4-digit long address, as long as the locomotive was being accessed using its 2-digit short address when programming mode was entered. To do this select CV18 and press the button then use the throttle knobs to dial up the desired 4-digit address to be programmed. When the new 4-digit address is in the display, press the button to write the 4-digit address to the locomotive.
