Up-date, JMRI / LocoBuffer USB / Soundtraxx PTB-100 / Digitrax DCS100 programming issues

Ok- seems like this setup is working... Some thoughts though....
-older decoder TCS TH120DP not in the JMRI list of decoders, it does not read CVs back to JMRI. But, will program... Just update the page and send the sheet.
-lights on this decoder still don't work properly. They are backwards... Front On when going backwards and vice versa.
-had a couple of decoders that were unresponsive with JMRI, upon assigning them to throttle... Got Status TRI. On the display, had to do a status edit to 128 (speed steps) and that fixed those.
Summary-take it slow and methodically, read the manuals again and keep at it.

Thanks for all the help

 Wow, that is quite litrally THE first TCS decoder produced. Only info I can find doesn't mention readback - I don't think they have any readback.

Are the lights backwards because the loco is run long hood forward but forward is short hood, or vice-versa? Check your defaults, CV49 should be 0, CV50 16. If this results in backward lights, change it to CV49=16 and CV50 = 0.

Woo Hooo, that did it.... JMRI didn't list this decoder so I just picked one (Mx series). It showed defaults of cv49-16 & cv50-0. Wrote those cv's to the decoder just to confirm. Yes still the lights were reversed. Then programmed as Randy suggested cv49-0, cv50-16 now the lights are working correctly. Conrail ran their gp40s short hood forward as I think most Railroads did by this time. And yes this is an old decoder... Working just fine now.
Thanks everyone ... Especially Randy!!
