Does any one have any experience with the Yamaha NHB32-c network controller, I keep getting the run around and figured this would be a good place to check. I have the entire network built around the nhb32-c and working for audio flowing from input of the ad8hr's to the actual channels of the console. However it is all useless without HA control, the issue I see is that discovery cannot change any variables on the nhb32-c at all and amp manager via usb does not have any actual functioning with the data protocol that is running. I realize only one protocol is allowed at one time but how do you tell the unit to do the head amp remote and not program change mode. When I look at the serial rx and tx ports they are both set to 01:60:2B:FF:88:00 and I cannot change that value as I get write errors when I try and change any value. I know the last octet is the serial number from 1-15 and I assume it changes them to 00 when it is in a mode that doesn't support serial head amp remote mode.
