KB923 CV19, CV21, CV22 - Advanced Consist Address/Function Controls

Most customers that use Digitrax command stations use Universal Consisting instead of Advanced Consisting as described here.  With Universal consisting, the consist information is handled by the command station instead of by the decoder.CV19 is the advanced consist address. CV19 also contains data for the direction in which the consist will operate. See the table below to determine what value to program into CV19 CV19 Value Effect on Adv Consist Address Normal Direction of Travel of Advanced Consist 000/x00 Advanced Consist Addressing Disabled N/A 001/x01 to 127/x7F Advanced Consist Addressing Enabled Forward 129/x81 to 255/xFF Advanced Consist Addressing Enabled Reverse ...

The display should now show both locomotive numbers. 6. ...

KB572 DT400 Series Throttle - Removing A Loco From A Consist

  To remove a loco address from a consist using a DT400 or DT402 Series throttle: Note: Duplex Radio throttles can remove locos from consists without the need to plug in to LocoNet.  Simplex Radio & infrared throttles must be plugged into LocoNet to remove loco addresses from consists. 1. On the L Throttle Knob, select the loco address that you want to remove from a consist. 2. Press the MU Key to enter consist mode. 3. Press the N - Key to remove the loco address from the consist. 4. The L Throttle automatically becomes active with the loco ...

KB728 DT402 & DT400 Series Throttles - Controlling Functions For Locomotives In A Consist

Even though an individual locomotive is part of a consist and you can’t control its speed and direction separately from the consist, you can still control its function outputs independently as follows:1. Press the LOCO Key and select the address of the locomotive that is a part of consist for which you want to control functions.2. Press the LOCO Key again to select the loco address to your throttle. The speed value will show “cn” to remind you that you can only control functions on the loco and not its speed.3. Use the steps described above to turn on or ...

KB709 UT4 - Consisting, MU'ing, or Multiple Unit Operations

Consisting is the action of linking more than one locomotive or power unit together to be controlled by a single locomotive address.  The UT4 is not capable of building or breaking up a consist.  This is handled by a throttle or computer program that is able to build and break up consists and then hand the consist off to the utility throttle operator.  Utility throttles are designed to be simple to use for operators on the railroad.  The UT4 CAN control a consist by selecting the address of the TOP loco in the consist.  It can also control the functions of locomotives within a consist.If ...

KB563 DT402 & DT400 - Multiple Unit Operation Consisting

To run two or more locomotives together as a multiple unit lash up or consist controlled by a single locomotive address: Place the two or more units you wish to MU on the track. 1. Select the TOP loco (the one that will control the consist) on the right hand throttle knob. 2. Select the loco to be added to the MU on the left hand throttle knob. 3. Make sure all the locos in the consist are traveling in the same physical direction on the track (both going to the left or to the right) 4. Press the "MU" key 5. Press the "+" key 6. ...

KB180 Q&A - Helper District & Nesting

Is it possible for the same locomotive to be part of more than one consist? In the strictest sense, no. Nor would it be a good idea to do so since you could never be sure who is controlling a particular locomotive. It is possible to join one consist to another in what is called nested consisting. Suppose I want to use a locomotive as a helper to get trains up a steep grade. I would need to form it into a consist with several different main line locos. Is it possible to set up several consists (each made up ...

KB757 DT402 & DT400 Series Throttle MU Key

The MU Key is used to enter consist or multiple unit (MU) set up mode.Once the MU Key is pressed, you will be prompted by the throttle to use the Y+ Or N- Keys to add locos to or remove locos from consists (MUs)

KB837 Zephyr Xtra and Zephyr - Multiple Unit Locomotive Operations

  MU (Multiple Unit) OperationsIt 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 locomotives. This is called Multiple Unit Operation or MU operation. With DCC, each locomotive is separately controlled. But in the case of MU'ing we would like to have more than one locomotive address controlled by a single throttle to simplify MU operation.Your DCS50 uses universal consisting to ...

KB585 Locomotive Orientation In An MU

Q:  How do you reverse the direction of the engine so you can run them on the same train with one in the backwards position?A:  Before consisting the locos, make sure that both are traveling in the SAME PHYSICAL DIRECTION ON THE TRACK.  The locomotives can be arranged in either orientation hood forward or backward as long as they are set to travel in the same physical direction when you set up the consist.(The direction indicators on the throttles may or may not match, the important thing is that the locomotives are set up to move in the same direction and are ...

KB280 Matching Speeds inside a consist

How do I get all the engines of a consist to run at the same speed? I have 3 engines with DH163A0 decoders and one with a MRC sound decoder. All units have the same top speed, but the unit with the MRC decoder starts and accelerates more quickly. Getting a group of locomotives to operate at the same speed can be a challenge. Experience has proven that it is best to work with the slowest locomotive and bring the other locomotives into agreement with that engine. Since the others appear to be in general agreement, it would be the ...

KB468 Zephyr - Consisting Tail to Tail

Q:  I'm wanting to know how to MU two locomotives together that are in a tail to tail configuration. I know that this can be easily done with a DT400 or DT402 throttle but not sure how to do it with the Zephyr. A:  Make sure all the locos in the consist are traveling in the same physical direction on the track (both going to the left or to the right). Remember that "reversing" takes place in the locomotive not on the track, so it is important that the engines be traveling in the same direction when they are MU'd.  ...

KB571 DT400 Series Throttles - Nested Consisting

When a consist is added within a different consist, this is called a nested consist.1.  Select the TOP loco of the consist you want to control the nested consist on the R Throttle.2.  Select the TOP loco of the consist you want to nest on the L Throttle. 3.  Press the MU key followed by the + Key to create the nested consist.4.  When it is added to the current R Throttle “TOP” loco it will become a “nested” consist. The nested consist is MU'ed and is part of the new nested consist. To remove a consist from the nested consist, select the TOP loco of ...

KB540 How do I turn off speed stabilization (Back EMF)?

Q:  Since the back emf torque compensation feature make consisting a real headache, I would like to know how to switch that feature off. Prototype loco's don't have such a thing so that slowing on a grade isn't really a bad thing in a model, either. A:  You can turn turn the speed stabilization on or off with CV57.  The CV value range for CV57 is 0-15.  If CV57 = 0, speed stabilization is OFF.  If CV57 = 15, speed stabilization is fully on.  All values in between let you scale how much speed stabilization you will use with each ...

KB573 DT402 or DT400 MU Adding a Locomotive to a Consist

Duplex Radio throttles (D throttles), do not have to be plugged in to add loco addresses to consists. Simplex Radio (R throttles) and Tethered/Infrared throttles must be plugged in to LocoNet to add loco addresses to consists.  To set up a consist using your DT400/DT402 Series throttle: 1. Select the loco address of the TOP loco on the R Throttle Knob. 2. Select the address of the loco you want to consist to the TOP loco on the L Throttle Knob. 3. Move the two locomotives into position. The locomotives can be headed in either direction. They can be adjacent to each other ...

KB574 Consisting, Which is the TOP locomotive?

Digitrax defines the TOP loco as the loco on the R Throttle Knob at the time when the MU add is performed.  This will be the locomotive address that controls the consist.

KB575 Multiple Unit or Consist Operations - Overview

Digitrax Command Stations offer three methods of multiple unit (MU) or consist control:1. Basic Consisting2. Advanced Consisting3. Universal Consisting (the Digitrax preferred method) By definition, Digitrax always adds loco addresses to the “TOP” loco address in a consist.   The “TOP” loco is special, in that it is the address that receives the speed & direction commands for the entire consist.   All non TOP loco addresses added to the consist are controlled by commands sent to the “TOP” loco.   The TOP locomotive does not have to be a physical loco on the track, it can be a phantom. ...
