Independent LocoNet Power

     Digitrax uses a technology it calls LocoNet to connect throttles and other devices to the booster, the component that supplies power to the track. Many throttles draw power from the LocoNet. If there are too many throttles the voltage on the LocoNet drops too low and the LocoNet stops working.

ARE Configuration

     The ARE configuration of throttles on the LocoNet looks like this:

     Independent powering the LocoNet takes the load off the booster and provides "keep alive" battery-saving power for throttles that require it while allowing you to turn the boosters off between sessions.

About LocoNet Wires

     As supplied by Digitrax LocoNet uses a 6 wire flat cable that may be crimped onto a RJ12 6 pin telephone-style plug. The left 3 wires are a "mirror" image of the right 3 wires. The purpose of the wire follow. The colors might vary depending on the cable manufacturer.

     Wires 3 and 4 are LocoNet power (red & green). Wires 2 and 5 are LocoNet Ground (black & yellow). Wires 1 and 6 are the LocoNet signal (white & blue). Suprisingly, the throttles draw their power from wires 1 & 6 (white & blue).

Inserting An Auxiliary Power Supply

     The ARE uses a "wall wart" power supply instead of the booster to power the throttles. A "wall wart" one of those small box-like power supplies about 1" × 1" × 1.5" that plugs directly into an outlet. The one used is labeled 12v dc, but puts out 18v open circuit. It is rated 400 mA.

     Open up the LocoNet cables going to the throttle jacks from the booster. Insert a DPDT switch to enable switching powering the LocoNet from the booster or from the external 12v source. The Rail-Syncs (white and blue wires) is connected either to the boosters or to the external 12v supply. A fuse is inserted for safety.
