DCC DECODER TESTER

Decoder tester, all in one board. Allow the testing of:

1. NEM658 (PLUX22, PLUX16, PLUX12) decoders
2. NEM660 (MTC21) decoders
3. NEM652 (8 pin) decoders
4. NEM651 (6 pin) decoders
5. NEM662 (NEXT18 and NEXT18/s) decoders
6. Wired decoders (through 5mm - screwed headers)

The main features are:

• Standard, 12VDC, brushed motor (with rotation sense display)
• 8 Ohm and 100 Ohm loudspeakers, commutable via hardware switch
• Shows the status of functions up to AUX11 with white LED
• Amplify the status of functions AUX3...AUX11 with electronic driver
• Up to 18 pin connections for wired decoders
• Support (via hardware switch) for NEXT18 decoder with and without sound
• DCC input connector with DCC presence indication

This is the final realization of the project:

And the testing with 3 different decoders connected to the PLUX22, MCT21 and NEXT18 connectors.
