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:

1. Gaugemaster GM500 Self Latching Relay
2. Two 3mm LEDs on the control panel to indicate which route has been thrown
