Digitrax Real FX3

• Turn functions on and off. 
• Head lights and tail lights are automatically reversing unless you make them independent. 
• All function outputs have FX generators for prototypical lighting effects and have qualifiers for FX effects and qualifiers for standard on/off functions.
• All Digitrax Series 3 decoders have FX3type functions.
• FX3 decoders offer full function mapping so you can choose which function (F0-F12) controls each function lead.
• FX3 decoders offer master light switch capability.
• FX3decoders offer qualifiers for FX function operation qualified by one of the following:  the loco's direction of travel, whether F0 is on or off, loco direction and F0, or whether the loco is moving or not. These qualifiers are also available on function outputs that are used as standard on/off functions.

Motor Isolation Note:  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.

Here is an explantion of how the CVs that control FX3 effects work.  Most modern Digitrax systems do not use hexadecimal format but it is provided here in case you need it for older systems.

CV 49-52, CV113-116, CV62 & 63: Digitrax Real FX3 Special Light Effects

Decoders with FX3 features have 8 user configurable, independent special effects generators.  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 consists can be controlled, too.
