Flashing TOC2

David Lenz 2 years ago in IQANdesign • updated by Chris Litwin 2 years ago • 2

I am trying to flash some TOC2 units to replace some units in the field. I have installed the "latest" IQANdevelop (G4) and have tried to send the program to the TOC2. I've connected to the TOC2 with two different USB to RS-232 adapters (one was Prolific chipset and the other was FTDI). I'm getting one of three fault messages when I try. Invalid form, Invalid data, or Bad Checksum.

I've tried with two different computers, one running Windows 10 and the other running Windows 7, and both seem to be the same. I tried swapping the data lines and just got a timeout message.

Any other ideas? I know this hardware is older and it's a challenge connecting to it with new machines!

Wanted to close the loop here. Finally tried a third USB to RS-232 adapter and it worked perfectly. It was a Trendnet with Prolific. These things are very picky.

We have a prolific, I don't remember which model, but if I connect it to a different USB port than originally installed on I have to reset the driver. It truly is a pain. I found the attached app to reset it, maybe it will be useful to someone.
