Hey guys,

I’ve got a triplex TAC50 controller and one of the cars just randomly stopped working. Can’t even run on inspection. We have an IMS computer on site but it it stopped communicating at the same time as the shutdown. It will communicate with the other 2 cars no issue.

CPU board light is on solid green

DSP indication light also on solid green.

No blinking. Any suggestions? Things to check?

Turned out to be the DSP board

You need to do the confidence test with Hyperterminal. It’s in the manual.
