Lashup Problem

What version of DCS are you using? If you press READ, can the remote find the TIU and what is displayed on the remote's screen?

At one time lash-up info was stored in the tiu .( all sorts of problems). Anyway I would make sure the engines you want to use to create the lash-up run ok as a single units and then delete the lash-up from the remote and start over. You may even have to reset the tiu as a last step. 

 Delete lash-up from remote , reset the tiu ,  create new lash-up.

I'm using version 2.1

That's the problem. There's nothing to discuss until after you upgrade your DCS. Honestly, troubleshooting a DCS release that's 14 years old is a waste of time.

You definitely need an upgrade to operate  proto-3 engines . At least version 4.2,  you might as well go straight to  the latest    version 5.....

However you still should be able to create a lash-up with version  2.1 with proto-2  engines. The batteries  needs to be  fully charged and in  good shape. The engines may remember their established ID created when the battery was in good shape but the battery  also needs to be in good shape when creating new  lash-ups.   If not you're beat.

Gregg and Barry,

Thanks much for your help.  I suspected that my lack of updating to a newer version might be the problem.  Was just too lazy to go about it.  Now I have some incentive.  Will get my copy of the "O Gauge Companion" book out and follow the upgrade instructions.  Thanks again for taking the time to assist.
