The LaisDcc 860033 DCC Decoder Tester Pro is a comprehensive diagnostic board designed to test model railway decoders before permanently installing them inside a locomotive. It allows modelers to verify motor control, lighting functions, and sound outputs safely using standard DCC command stations.
Integrated Interfaces & Connectivity
The tester functions as a universal test bench by including native socket connections for almost every major model rail scale standard:
- 21MTC (NEM660) standard sockets
- Plux22 / PLUX16 / PLUX12 / PLUX8 multi-stage interface
- Next18 compact socket common in N gauge models
- NEM652 standard 8-pin harness socket
- NEM651 slim 6-pin harness socket
- Screw Terminals & Solder Pads for bare-wire decoders or connecting crocodile clips
Core Technical Features
- Built-In Protected Motor: Features an on-board motor with protection circuitry to prevent overload damage to unverified or faulty decoders.
- On-Board Test Speaker: An integrated speaker allows instant testing of audio files and sound mapping on sound-equipped chip
- Dual Power Input Modes: Offers two track connection pathways—Supply A (constant pass-through) and Supply B (routes through a switchable on/off toggle button for safer desk testing).
- Visual LED Feedback: Clear array of directional and auxiliary LEDs to check headlights, tail lights, and independent function outputs without complex wiring.
