“Communication timeout error. Please check the connection and verify that 2Way Remote is set to Not Used.”
I had been using the RS232 connection with my remote control which is working fine, getting back info from the AV8801. There is a one time setup for RS232 usage in the AV8801 manual (which I did), but there is no description on how to turn it off. I reset the AV8801 back to factory settings a couple of times, but that did not help.
Anyone have any experiences with this error?
Yes, I have experienced this error and have reported it in this thread. It is even referenced in the Pro FAQ.
This is a PC-side issue. If there has been no activity on the USB-to-Serial interface for a certain amount of time (only a couple of minutes), then the interface ties out. The next time Pro tries to communicate with the AVR, you get that error message. The fix, or work-around, is to first acknowledge the error, then briefly unplug the USB side of the cable from the laptop and plug it back in. This resets the connection, and you should be able to proceed.
The timeout can occur if you spend too much time moving the mic to a new position, or (most commonly) when you spend too much time trying to decide which crossovers to use on the results page, before you save the settings to the AVR. Once you understand what is causing the error, the work-around I describe seems to be reasonable to me. Regardless, it is not IMO an Audyssey issue.
