QSI Revolution / Magnum

The correct name for this decoder is the "QSI Revolution", but there was a lot of confused marketing, where people saw the board packaged with a screw terminal board, and the board or board and decoder marketed as the "Magnum".

In any case there is only one version of the hardware, although there were some modifications to cut off certain pins that caused trouble in some implementations. (Too many people not following the "Aristo socket" standard.)

Wiring Diagrams and pictures:

Here's a diagram of the board with connections. NOTE! The connections on the "magnum" board are WRONG. Read the silkscreened letters by the screw terminals. The headlight (FL) and the backup light (RL) are reversed from the picture below.

Note: all the connectors are different.

P9 - 2 pin speaker connector - can get spares from All Electronics, part SBC-1

P2 - 3 pin chuff switch connector - only pins 1 & 2 are used. (I have a lot of spares, always order the steam version, then you get one of these cables with each decoder

P5 - 5 pin flat cable, comes with the Airwire receiver. NOTE: the cable only has contacts on one side, likewise the sockets on the AirWire receiver and the QSI board have contacts on one side. The is far and away the most common issue people have when connecting this. Use a magnifying lens to be sure on the sockets.

P3 - you can't use this, so never looked into it, they were going to market an add-on device with more light ports.

P1 - small 2 pin connector for the reed switch - you get a reed switch with every decoder, I never use them

Sounds:

The Revolution only accepts Q2 sound files, and not to be confused with the Titan Q2FX,  files. (Q3 files are exclusively ET - Emulator Technology).
