Hey, look! Progress already.

I can get monitor ID 1 to respond, but if I change the ID in that monitor's OSD (it will eventually become ID 3) I can't get it to respond. I also tried sending to ID ALL (2Ah) and no response.

This power on works for ID 1 (from RTI library)
01 30 41 30 41 30 43 02 43 32 30 33 44 36 30 30 30 31 03 73 0D

This power on should work for ID 2 (changed third section to "42" which should map to ID 2 instead of "41" which is ID 1)
01 30 42 30 41 30 43 02 43 32 30 33 44 36 30 30 30 31 03 73 0D
--doesn't work

This power on should work for all monitors (listed in documentation as 'A'(2Ah))
01 30 2A 30 41 30 43 02 43 32 30 33 44 36 30 30 30 31 03 73 0D
