Is anyone here well-versed in the AHM TCP/IP protocol?
At the moment, I’m able to control mutes and recall presets successfully, but I’m stuck when it comes to controlling and reading the Source Selector from a third-party device.
Some of this is almost certainly user ignorance, but I’m fairly confident I’m generating the correct messages based on the protocol document.
I’m using Packet Sender for testing and have confirmed that I can connect to the unit and control mutes this way. According to the end of page 4 in the protocol doc, the hex string for recalling “Source 1” on Zone 15 should be:
F0 00 1A 50 12 00 08 0E 00 F7
I have a few questions about this message:
• In the SysEx header, there are fields labeled Mv and mV (Major Version and Minor Version), but I don’t see any explanation of what values these should be or how they’re used.
• In the protocol sheet, the byte “08” is shown in red. I’m not sure what the significance of that is.
• Does it matter that the zone is stereo?
If anyone has experience with this and can point me in the right direction, I’d really appreciate the help.
