Trouble With My First DCS Upgrade

I would start over including shutting down  the computer. Follow the on screen instructions exactly. no short cuts.  Do the tiu first. 

FYI, after removing the jumper cable from the TIU, it's necessary to restart the TIU before proceeding with the remote upgrade.

I have seen guys try to do the remote thinking the jumper on the TIU should be in place.  Barry's book covers all of this very well.

Gregg, Barry, and Marty,

Thank you so much for the advice.  I restarted the computer, then did the upgrade to the TIU.  At the end of that upgrade, I saw where it told me to unplug the mini to mini and cycle power.  Overlooking the message to unplug the mini was my downfall.  I was then able to upgrade the remote successfully.  I wondered if I could run the upgrade to the TIU without harming anything, but wanted to be sure since I never did it before.  Working in Electronics for over 38 years, I have seen devices that are unforgiving, but must admit most were in the earlier days of processor based devices.

Many thanks to you fellows for answering the same questions over and over to folks who are new to DCS, and are afraid to do something that will cause the need to send the unit in for professional repair!!

Oh, yes, here is the proof of the pudding.  The display shows 4.3, and I was able to run my Hudson right off the bat.

It cannot be overemphasized:  Start the computer program and select the function you want to perform, before doing powering up anything with the remote or TIU.  Then follow the on-screen instructions exactly, and in the order given.  If you err or there is a problem, shut down the TIU and remote completely and restart from scratch.
