Page 8 for the 4308CI documentation clearly indicates device 4.5 for XM radio in the right hand column but the binary representation appears to be a typo or misprint.
Please disregard my statement in my last post about device 7.5 being synonomous with ID set #3. I responded in haste and I was mistaken.
Take the decimal documentation in the right hand column on page 8 as the accurate device number for each function set.
The perhaps non obvious fact in the documentation is that all of the Kaseikyo function codes for IDs #2-4 are mapped the same relative to eachother within each ID code. ID#1 is somewhat different because it uses a mix of the older Denon-Sharp protocol and the newer Kaseikyo protocol. Each of the four ID codes (accurately listed on page 8 and only applicable to the kaseikyo codes!) place each ID set in a different range of function numbers:
To test this, combine the binary function codes with the desired ID code to convert to the proper decimal representation of the function code.
Examples:
Return (ID#1): data 0100010000 + ID 00 converts (as described earlier) to 34 Return (ID#2): data 0100010000 + ID 10 converts to 1058 (1024 + 34) Return (ID#3): data 0100010000 + ID 01 converts to 2082 (2048 + 34) Return (ID#4): data 0100010000 + ID 11 converts to 3106 (3072 + 34)
