ACjr Firmware Upgrade

[blide]

Checking to see if anyone can help me with upgrading my ACjr with serial. It's currently running rev 3.20J - CC06 and I'm wanting to get it up to date with the latest 3.3_1AO8.

I followed all the readme steps and nothing is happening... The controller just says loader and my PC transfers to 100% and nothing happens? The readme says "You should see a p[xxx] displayed on the second line of the LCD display if the update is working." and I don't see that anywhere.

I tried it with and without the probes plugged in an no change...

Here's what I typed and I tried all com ports and nothing...

Update... Talked to Curt and his recommendations worked!

Here's some troubleshooting tips I think should be add to the readme file:

1. Before booting the ACjr to "Loader" mode unplug everything expect the serial cable (No PH, Temp, or DC8) then boot it up.

2. Make sure you're not using the ground serial adapter on the PC. Just use the serial cable with no extensions or adapters.
