ERR Railsounds commander (new version) and TAS Universal Command Upgrade Board

Trainman2OGR Forum Member

I just acquired an older Train America Studios Universal Command Upgrade Board, and I installed it in a Williams Trainmaster. It seems to work well for forward and reverse (haven't added lights yet), but I'm having trouble trying to connect an ERR railsounds commander (the new single-board). I even tried connecting the jumper wire to the number 20 pin, and another wire to the number 24 pin, and connecting them both to the purple serial data cable, but when I power up, the sound still comes on immediately, and the horn and bell won't work with the Cab-1L remote, even though they work off the transformer buttons.

Is there any way to interface these boards so the TAS bord will operate the Railsounds commander?

Thanks.
