I suddenly noticed that my volume buttons weren't working anymore. I was getting the "command failed" message with each push. On further assessment, I learned that none of my commands for my Marantz AVR or Marantz DVD are working. All give me "command failed". These are the only two devices that I have as of now that are controlled via my RFX9600 with serial command. However, all my other components that use IR (also routed through the same RFX9600 and same wifi access point) work flawlessly.

If I switch to a page where I have all my codes for the serial devices and if I rapidly repeatedly press the same command it will eventually respond.

This was sudden, during normal use. I had not even connected my Pronto to my computer and used Pronto Pro Edit in a few weeks. I just tried downloading my saved config into the Pronto but it has made no difference.

Does anyone have any suggestions? Thanks,

Marc
