FX3 decoders have motor isolation protection. If the decoder senses that the motor is not isolated, it will not run the motor. In this case, you will be able to control the loco’s functions but the motor will not work.FX decoders will blink the loco's lights when power is first applied to the decoder to warn you of a short circuit in your installation. If you see the lights blinking, immediately remove the loco from the track, locate the short circuit and correct the problem before proceeding. Do not leave the loco on the track with blinking lights because eventually, ...

Many locomotives feature warning lights that are designed to make a train more visible to the general public. FX Functions are function outputs that incorporate 4 FX generators for prototypical lighting effects such as Mars lights, ditch lights, Pyle Gyra-lights, rotating beacons, single and double pulse strobe lights, and random flicker.

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, ...

Flashing ditch lights can be set up with several CV's. Using 1.5 Volt Bulbs or LEDsIf you use 1.5 V bulbs, you must install a current setting resistor with a minimum value of 100 ohms for each bulb.Typically a 560 ohm 1/4 watt resistor works well for a grain of rice bulb and a 250 ohm 1/4 watt resistor works well for a grain of wheat bulb.Lower resistance values will increase the lamp brightness. If you use LED's be sure the polarity is correct when you hook them up & install a current setting resistor for each LED. Typically a ...

If the sound output from your SoundFX decoder is distorted, try the following:1. Check the speaker cone for magnetic debris that may have collected there. Debris on the speaker will cause a loss of sound quality and must be removed.  This is a common problem in speaker installed facing down toward the track.  Remember, speakers are magnetic and will vacuum up magnetic debris along the track.2. Be sure that the CV58 volume is not set at a level that is too high for the speaker. For impedances below 32ohms (e.g. 8 to 30 ohms) set the volume setting lower to ...

The sound in your decoder shuts down after you stop it and you are not using a Digitrax system for control. On some DCC systems decoders are not addressed by DCC packets after the locomotive is set to 0 speed. In this case after the CV11 timeout elapses (6 second factory default setting for SoundFX decoders), sound will shut down. To remove the timeout and prevent sound shutdown, set CV11=00.  This would leave the sound in the locomotive on until you remove power from the loco.Digitrax command stations continue to refresh locomotives by periodically sending packets to them as long ...

Q:  I have a DH163D decoder. How do I program it so the Mars light works? A:  Any function output on Digitrax FX decoders can be set up for any FX effect by programming its associated FX CV to the appropriate FX CV value. For example, if CV52 (the FX CV for F2), is programmed with a CV value of 034, the violet wire F2 function output will be a Mars light when F2 is turned on for this decoder address and the decoder's direction is forward.

In FX3 decoders, CV54 is used to control the decoder's torque compensation and switching speed features. CV53 is not used in FX3 decoders.Torque Compensation improves loco performance by internally adjusting for the loss of torque caused by SuperSonicTM operation.  This feature is turned on at the factory.Switching speed gives you fast access to lower speeds used in switching operations. This feature effectively reduces the throttle's target speed by about 50% and reduces the effects of acceleration (CV03) and deceleration (CV04) programmed into the decoder by 1/4 when the user activates this mode by turning on F6.FX3 CV54 Values For Controlling ...

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 ...

Current production Digitrax decoders use the following numbering system: The first character means that it is a digital decoder. This is always a “D”. The second character indicates the decoder’s physical size. This is based on the smallest "scale" the decoder is designed to fit. This will be a Z, N, H, or G. The third character is the current rating of the decoder. This will be a 1, 2, 3, 4 or 5. We designate 1.25 & 1.5 amp decoders as 1s and 3.5 amp decoders as 3s for simplicity. The fourth character indicates how many functions, including directional ...

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 ...

CS (configurable strobes) are function outputs can be set up to be simple on/off functions or as single or double pulse strobes. The CS option was available in very early decoders where there were not enough resources to allow for full FX functions.

 Digitrax Series 3 Decoders include the following features and more: FX3 Function Outputs Supersonic motor drive for quiet operation Support for all DCC programming methods One-Step decoder factory CV reset Motor isolation protection White or Golden Yellow LEDs on decoders that come equipped with LEDs Operations mode read back capability for CV read back on the main line

Can the SoundBug sound like a juice jack, i.e. a GG1? Yes. The SoundBug, like all Digitrax Sound FX decoders, can be set up with any available sound project. Any recorded sounds can be set up as a sound project file (.spj) which relates the sounds to individual actions of the locomotive. Many project files are available on the Digitrax Sound Depot and on the web.  Sound projects are free.

The sound project loaded into this decoder can be operated independently of any other DCC motor or function decoder. If another non-Sound FX compatible DCC decoder is connected to the track leads then CV readback of SFX064D Sound CV's and PR2/PR3 SoundTest modes may not be possible. Note that it is always possible to Write CV values using Operations mode or a Service Mode programming track, even if CV Read is inoperative.If the connected function loads are insufficient for CV readback or an incompatible DCC decoder is also connected, it is still possible to download a complete sound project by ...

If you have trouble reading back CV's on the programming track, this may be due to insufficient current draw on the SFX064D function leads. You can always just re-program the CV value into a CV to get the desired results, even though reading CVs does not work. OPs mode is recommended for programming all CVs except CV01, CV17 & CV18 (2 digit and 4 digit addresses). If a second DCC decoder is present that is not Sound FX compatible then correct readback of CV data is not possible, since the NMRA CV readback was not designed for multiple decoder readback.

What are the different operational modes available in the PR3? The PR3 is the combination of two previous Digitrax devices: the PR2 decoder programmer and the MS100 LocoNet to computer interface. The PR3 can be configured through manual (control panel buttons) or automatically (software) means to perform any one of the following three operations: a) The PR3 can be configured to function as a stand alone decoder programmer. In this mode the PR3 can program the configuration variables of most DCC decoders and the sound effects of the Digitrax Sound FX sound decoders. b) The PR3 can be configured to ...

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 ...

Configurable strobes are set up using CV's 49, 50 and 61. Configurable strobe function leads can be programmed with a limited number of simulated lighting effects similar to FX effects but without as many options.

In addition the PR3 can write to and read from any CV of most current non sound mobile and function decoders found in today's market place. 2) Digitrax command station LocoNet to Computer interface As a layout control tool the PR3 is a second generation ...

What about using a Digitrax-decoder-equipped locomotive on a layout having only DC power?It is possible, but analog operation of DCC equipped locomotives is becoming a bit of a rarity. In earlier times some locomotives were delivered from the manufacturer with a DCC decoder in place and a jumper plug was used to select the operating environment. Digitrax still offers a jumper plug for use in some configurations; you remove the decoder and replace it with the DHDP or DNDP. With later generations of decoders, it is possible to operate on a DC layout with the decoder in place. To quote ...

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 ...

  CV29 is assigned a single value which chooses a combination of specific effects: 1. Speed step control. 2. Speed table On or Off. 3. Analog mode conversion On or Off. 4. Normal Direction of Travel (NDOT). 5. 2 digit addressing or 4 digit addressing. Analog Mode Analog mode conversion is very convenient if you plan to run your Digitrax decoded locomotive on regular DC layouts. With analog mode conversion enabled, the decoder will automatically begin operating as a DC locomotive when no DCC signal is detected by the decoder. This means that if you place your Digitrax decoder equipped ...

Three Step Speed Table CV02 V-Start (Start Voltage) CV06 V-Mid (Mid Point Voltage) CV05 V-Max (Maximum Voltage)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 ...

Speed stabilization is a feature that causes the decoder to run the locomotive at a somewhat constant speed according to the throttle setting. This means that if you set your throttle to 21% of total speed, the decoder will force the motor in the locomotive to maintain a constant speed at that level no matter what the track gradient or the load on the locomotive. The SD9 is an example of a US prototype that employed a load compensating type of control technology. Many modern European locomotive prototypes use some form of load compensation of the prime-mover in response to speed ...

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 ...

CV54: Torque Compensation & Switching Speed In FX3 decoders, CV54 is used to control the decoder's torque compensation and switching speed features. Torque Compensation improves loco performance by internally adjusting for the loss of torque caused by SuperSonic™ operation. This feature is turned on at the factory. Switching speed gives you fast access to lower speeds used in switching operations. This feature effectively reduces the throttle's target speed by about 50% and reduces the effects of acceleration (CV03) and deceleration (CV04) programmed into the decoder by 1/4 when the user activates this mode by turning on F6.

CV08 is the factory reset CV for all FX3 decoders and also the Manufacturer ID CV for all decoders.When you read the value of CV08, Digitrax decoders report back "129".To reset all CV values to their factory default, program CV08 to a value of 008  while the locomotive is on the programming track.To reset all CV values except for 28 step speed tables to their factory values set CV08 to a value of 009.Note:  Performing a factory reset will not affect the manufacturer ID and will reset the decoder's address to the factory default of 03, a 2 digit address.
