Product Support for: Computer Control -> Computer Decoder Programmer-Serial (PR1)

Setting Up a Mars Lights with the PR1To program the decoder for Mars Light or other "single" output applications, follow these steps:1. Go to the Digitrax Decoder Programmer2. Select FX Set up3. Choose the function that you want to be the Mars Light4. Select "Mars Light"5. Click "OK"6. When you are back in the main screen click "Send"

The following CV set up simulates prototypical ditch lights that are on steady when running and alternately flashing when the horn blows. The ditch lights will be on when the engine is running, when you simulate blowing the horn by going into function mode and pressing F2 the ditch lights will flash on alternate sides of the loco. Note, the F2 key on Digitrax throttles is set up as a non-latching function so that the function assigned to F2 will be "ON" as long as you hold the F2 key down and will go "OFF" when it is released. Follow ...

When you click on the "FX-Setup" button a second menu screen appears which contains the special light effects for the FX decoder. If the decoder you are programming is not capable of FX effects, this section will not apply to your situation.On this screen we have access to F0 Forward Light, F0 Reverse Light, F1, F2, F3 & F4. The programming directions and choices are the same for each function. The pull down field to the right of this shows you which effect is assigned to that particular function. The following is a list of choices: No effect, normal function ...

This note addresses the installation of an H0-Scale wired decoder into Bachmann Plus ABA F-7s; it calls for using a DH140, which has been retired.  Current decoders such as the DH123 or DH163 or similar wired decoders can be used. Just finished up doing a few HO Bachmann Plus F7's, ABA's to be exact. Thought maybe some of you might be interested in how the DCC conversion went on these.They are an easy conversion!1.  The full stall current for these ranged from 500-700 ma for each loco . I selected Digitrax DH140 for the A units and a DH120 for the B ...

Decoders with FX function features have 4 user configurable, independent special effects generators. All current production Digitrax Decoders use FX3 functions so this article is not applicapable to these decoders. CAUTION: Decoders with FX3 function generators use different CVs to control the decoder outputs. All current production Digitrax decoders use FX3 function CVs. Before using these CVs to program your decoders make sure that they are FX and not FX3 decoders.The Real FX effects are set up by programming CV values as described below.F1/F2 NOTE: If using DH142, DN142, DN141K2, DN149K2 series decoder, when F1 is set up for FX, ...

Decoders with FX3 features have 8 user configurable, independent special effects generators.  All current production Digitrax Decoders use FX3 function features. These are set up by programming CV values as described below.  If your decoder is not a Series 3 decoder, please check the spec sheet to determine which type of functions it supports.FX3 functions incorporate FX generators with additional dynamic and static qualifiers.  FX3 functions are fully remappable so they can be controlled by any function key on your system.  A master light switch can be set up to turn off all lights on a locomotive. Functions associated with advanced ...

When you are using a throttle to control a locomotive, you will notice that as you increase and decrease the speed, the loco responds to the change in throttle settings according to the relationship between motor voltage applied and the throttle setting.  This is called the throttle response curve.  Decoders are shipped from the factory with a linear throttle response curve.  This means that as you increase the throttle setting from 0 to full speed, the loco will look like the default curve in this diagram.If you want to create a more realistic throttle response curve, you can set up ...
