GWire Receiver for Other Decoder Applications
Posted on 3. September 2009
From time to time we have had requests to use the GWire System for other decoders besides the Quantum Aristo and Magnum offerings. Currently the GWire System uses the NCE GWire ProCab Transmitter, the GWire Receiver and either the Aristo or Magnum large scale units.
Some large scale locos draw HO scale currents so the user can save money by using the the 2 Amp Revolutions. Here are diagrams and instructions for the HO/S Quantum Revolution.
Most other DCC mobile decoders and stationary decoders can also be connected to the GWire receiver. If you have a special request we can do the wiring for you or send the instructions.
Installing a QSI Solutions G-Wire Wireless Receiver on a Quantum Revolution-U Board.
Important!
The connections to the Quantum Revolution board are extremely delicate. A controlled heat soldering iron such as a Metcal with a very fine tip is recommended.
Once the radio is installed, you cannot use the DCC track for programming, upgrading, or operation unless the radio is disabled.
Before installing set the following CVs
- CV11 (Packet timeout) to 1 for a 1 second packet timeout.
- CV29 (Configuration data #1) to 2 for NMRA Digital Only.
Installing
Remove the protective sleeve from the board and make the four connections shown below using fine wire.

GWire DCC Receiver Connection to Generic DCC Decoder, Track Power.
Track Schematic
Diodes should be 1n4004 or typ. 1N4004 Micro 1-Amp Rectifier Diode: Radio Shack Catalog #: 276-1103
Or a bridge rectifier
1.4A, 100V Full-Wave Bridge Rectifiers Radio Shack Catalog #: 276-1152
Cap should be 220uf 35v, or whatever, for DCC the value isn't very important.

GWire DCC Receiver Connection to a Generic DCC Decoder and Battery Power
Here are some notes:
The drawing has two leds and two light bulbs to show alternate connections. The maximum voltage for the battery is 24V. You must make a ground connection to the decoder. The easiest place to find a ground on any DCC board, is the anode of the power diodes. (The anodes are the ends without the stripes) two of the diodes will be connected together and this is the board groundand not connected to the Red or Black wires.
If running a lot of lamps the 7805 may need to be attached to a heatsink. The mounting tab is connected to ground and is not isolated.
