I just purchased the tester and I have tested a couple of MRC 8 pin decoders and so far so good.
I also want to test an 8 pin Digitrax 004 Soundbug, but it does not fit in the 8 pin slot, whereas the MRC one does.
The Digitrax decoder is a narrower 8 pin unit, compared to the MRC decoder.
Is there some way of modifying it or adding an adapter, so I can test it?
If you solder, you could make a harness with a smaller socket wired to a wider plug, with the appropriate lines connected with fine wire and appropriately insulated and strain-relieved. You’d then have that as a tool going forward.
[EDIT - I did not read carefully enough. See below; the SoundBug is intentionally designed so you won’t plug it into a decoder socket by mistake!]

I’m not sure I quite follow what you are saying.
Is there an adapter that I can plug in the narrower 8 pin plug into?

Removed as irrelevant.
You have to make an adapter following the instructions Digitrax provides for using the Soundbug with a non-Digitrax decoder. The connector on the Soundbug is NOT a standard DCC connector, it is designed to interface with the connections on certain Digitrax decoders. The two screw terminals alongside it are the track inputs. If you manage to get the Soundbug simply plugged in to the decoder tester or in a loco without another decoder, you will likely fry it.

Thanks to everyone for your input.
I will try your suggestions.
