Tonight I installed the first Snap-It Accessory Decoder and it actually worked!
Furthermore it was not a standard Peco point motor installation. It was a Kato crossover using:
- Track Power from a Tam Valley 12v 5amp Accessory Booster
- Kato Scissors Crossing (with 4 point motors) Turnout
- NCE Snap-It Single Module
- External 470u 25v Capacitor added to the NCE Snap-It
- DCC Concepts DCD-SDC adapter from 3 wire to Kato 2 wire
- Single Pole Momentary contact micro switch
The turnout responded 100% correctly once I added the extra 470u capacitor. The Turnout is switched by:
- Toggling the momentary contact toggle switch OR
- Selecting Accessory Decoder 171 on the NCE Power Pro Hammer Head
Still to install in this first “Turnout Control System” process:
- Gaugemaster GM500 Self Latching Relay
- Two 3mm LEDs on the control panel to indicate which route has been thrown
