I recently moved my 3 box Vivaldi stack. After hooking everything back up I’m having issues with the RS232 connection. I can control the volume and put both the DAC/Upsampler into standby with Mosaic, but I can’t control any other DAC functions and the system info for the DAC is all zeros.
I already went through the manual and the FAQs here and checked everything suggested. I confirmed every item listed in these two FAQ entries:
Performing the suggsted volume test confirmed it’s an RS232 issue.
I even confirmed conductivity of the serial cable with a multimeter to ensure it was not damaged (2 pins are connected between the upsampler and DAC). Everything looks fine there. The cable has been removed an reseated multipel times too.
I have tried factory resetting both units. I have tried restoring my saved config on both units. I have powered down both units, let the DAC fully power up then started the upsampler.
I seem to be out of options at this point. Is there anything else I can try? Some kind of hard reset perhapes? I’m running the latest firmware on both units.
