Add everything in the string except the initial "AA". You can use the Windows calculator in hex mode for this. If the result is more than two digits, the checksum is the right-most two digits.

Ex. Power On - 11+FE+01+01 = 111, the chksum is 11, so the entire string is
AA 11 FE 01 01 11.

Ex. Input Comp - 14+FE+01+08 = 11B, the chksum is 1B, the entire string is
AA 14 FE 01 08 1B.

Does this do the trick?
