Please let me clarify one more thing. Only does the "second command code" seem NOT to be "COMP" when putting the values in RM. How did you firgure out about it?

When I converted the signal into binary form, it was obvious that the 2nd command byte wasn't the comp of the 1st command byte. For this upgrade, I didn't try to have the executor generate the 2nd byte, so I simply calculated it based on the binary and entered it into the KM file.

If you're curious as to the true structure of the data, I believe there are 3.5 bytes of fixed data, followed by 1 variable byte of data and a 1/2 byte checksum, where the checksum is an XOR of the previous 4 nibbles.

Here's the binary for the signals:
Code:
0000 0001 0001 0111 0100 1000 0000 0101 0000 1101 - obc 10 - Num 0
