Do I have a bad board

[willjayna]

I am at a loss. I recently purchased a Scale Trains rivet counter sd40-2 and I am adding a 21 pin Tsunami 2 decoder. I got it installed, soldered in the speaker which I used an ESU sugar cube and everything worked fine except the speaker wouldn't fit under the long hood.

So I tried to get it to fit under the hood by taking off the baffle didn't work and I think I may have damaged the speaker. So I then got a different speaker and after soldering it up I am getting no sound and no movement.

I am using the default number 3 address and all I am getting from the speaker is a soft clicking noise and the locomotive wont move. I am getting the blue light on the decoder but no sound and no movement.

How do I tell if the board is bad and if not why now am I getting no movement or sound.

Maybe read the manual.  I just took a look at it, and there is something about the DIP switch, and using only ESU decoders.

You can also talk to them, as I've gathered from other modelers that have their stuff, they are excellent to deal with.

Just my worth.

Have you tried resetting the decoder to factory defaults?

Well that's a new wrinkle.  It implies that some lighting features won't work with other brands.

 I found something I could cut and paste:

 

While the DCC-ready models do have all the same hardware installed in them for
the lighting functions as the sound-equipped versions do, unless the customer chooses to install an ESU decoder … such as a LokSound V4.0 sound decoder, or a LokPilot non–sound 21-pin decoder … there will be no way to access any lighting functions beyond the basic headlights, numberboads and white class light as mentioned above.

The reason for this is that there are just too many outputs to accommodate all the
lighting and/or sound functions on most standard decoders; there are 10 separate
outputs that are required to accommodate all the variations on the SD40-2, for example.

Even some ESU decoders do not have this many outputs, so additional hardware was included on the motherboard installed in the model to accommodate for them. This technology is proprietary to ESU, and therefore, other decoders do not have the ability to communicate with this hardware.

1) Have you reset the decoder? 

2) Is the speaker capable with the Tsunami 2 TSU-21PNEM audio amplifier: 2 Watts, 8-Ohm Load?

 They may simply be referring to ther extended functions being logic level (0 and 5, or more likely 3.3V) instead of full power (such as could be connected directly to a lamp). This is the difference between the 21 pin setup used by all the Euro decoders and the way the NMRA defined it. NMRA says all functions should eb full power, that means a lot more drivers on board the decoder. The Euro way puts the standard drivers on for the basic functions most everyone would use, and then leaves the additional drivers for those who want or need even more functions to be on the motherboard. It's not AFAIK proprietary to ESU, other Euro decoders work the same way. But maybe the did something with ESU and it uses something like an SPI or I2C bus to communicate the additional functions.
