Hi, Scott – thanks for your response.

This is a fully loaded system, so one of the AR84’s is directly connected to the expansion port. The other is fed from the AR2412.

The AR2412 works fine, but neither AR84 will link up with the system. I don’t recall if I tried moving the other AR84 from the AR2412 port to the console or not.

A technician finally contacted me late yesterday. Her recommendation is to downgrade the firmware on the desk to the earlier version to get the units working, then if successful, redo the upgrade to V 1.62 with the units all connected. (The desk was previously updated in the shop and not connected to the I/O rack).

Also, as a “Plan B”, I just received a brand new AR84 this morning, so I’ll make sure it works. Best case we’ll have a wpare/backup unit, worst case it’ll buy me eight more channels to use for rehearsals while we troubleshoot the others.

Thanks again for you suggestion!

Update – I just re-read the update instructions, and it says explicitly

“AudioRacks currently connected or connected later to the GLD will have their
firmware automatically updated by the GLD during the boot process”, which explains why I didn’t have any issues in the past. Kinda puts me back to square one.

Before anyone asks, I did open up the units and test the power supply voltages with a DVM, and they all looked good. I also saw that the multi-pin connector that connects the interface card to the motherboard was canted on at least one of the units due to the bottom board apparently flexing, with no support under it. I reseated the connectors on both units before reassembling.

Ideas? If I buy a new AR84, which I should probably have as a spare anyway, will it come with the newest firmware, or will I be in the same situation?
