Series 4 decoders like the SDH164k1's will conform to the 10-pin wiring diagram   Function pads for F1 and F2 are located on the SDH164K1 boards on opposite sides by the front headlight. Functions 3 and 4 are located on the 10-pin wire harness, with the Brown wire being the F3 negative and the Yellow wire being the F4 negative.  F3 and F4 functions have a common positive connection to the solder point labeled in the middle of the board.     The common LED sizes used are 3 mm and 5 mm.

My sound decoder has a capacitor, why do I need a PX112? The capacitor that came with your Digitrax sound decoder is designed to hold up sound operation in the presence of brief power interruptions.  It is not designed to keep the locomotive’s motor and lights running.  Our ears are very sensitive to sound interruptions so, the capacitor on your sound decoder will prevent most of these drop outs on average quality track.  Most people don’t even notice the small pauses in a locomotive’s movement and the small flashes of the lights when the track power is interrupted.  If you ...

Q: My front and rear lights on a steam locomotive (hard wired decoder installation) are connected in reverse. When the locomotive is going forward, the back up light comes on. When the locomotive is going in reverse, the forward light comes on. Can I reverse the lighting effects though programming the decoder or must I disassemble the locomoitve and physically swap the wiring to the lights from the decoder. A: Yes, you can do this with using function mapping in any Digitrax decoder Series 3 or later. If you have an earlier version decoder installed, you'll need to re-wire the ...

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 ...

Digitrax decoders have outputs that can control lamps and other on/off devices installed in your locomotive.  These are called functions.  Functions are things like: lamps, sound units, smoke units, etc. All Digitrax decoders are equipped with two or more function outputs that are used to turn functions on and off.Decoder function outputs can be:1.   Leads (wires) attached to the decoder that are used to hook up external functions.  See Table I below for wire color codes used on Digitrax decoders.or2.   Pre-wired function outputs that hook up by just plugging in the decoder. This is the case for decoders that ...

  How do I connect the BD4 to the DS54? The BD4 is a block occupancy detection device designed as an add-on device that can take advantage of the LocoNet hosting capability of the DS54 stationary decoder. It is connected in this way: The installation of a BD4 is relatively simple. Looking at the BD4, you will find a 5-point terminal block on one end and two (LED1 and DS1) 10-pin (5x2) headers on the other. There are three termination areas: a) The 5-point terminal block (left) is for the interconnection between the rail power source and the rails. b) ...

How do I connect a BD4 to a DS64? The BD4 is a block occupancy detection device designed as an add-on device that can take advantage of the LocoNet hosting capability of the DS64 stationary decoder.

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 ...

Digitrax series7 mobile decoders have many industry standard Configuration Variable (CV) numbers and values, as well as numerous Digitrax custom CV numbers and definitions or controls. The series7 CV values are a superset of older Digitrax FX3 series3 and series6 decoders, already covered in Digitrax Decoder Manual V2 on the Digitrax Web site. The “CV8 to 8 default” columns indicate current factory defined value after writing a value of 8 to CV8, using; Service mode programming track or Mainline Operations Mode Write to the active decoder address. An entry with value/xx indicates a xx number invokes the value before the ...

Digitrax Complete Train Control By Zana & A.J. Ireland Digitrax Complete Train Control makes reliable, realistic train operation and simplified layout wiring a reality. Digital Command Control is incorporated within the Digitrax system to let you control multiple trains independently on the same section of track without blocking. In the real world, engineers control the speed and direction of real trains. Engines operate under their own power independent of the track. Each engine has its own motion characteristics like how fast it speeds up (acceleration) and how long it takes to slow down (deceleration). A locomotive's performance is influenced by ...
