Correct about TT. It is indeed strange. There are one or two bits between pressure and temperature that may be some kind of checksum or parity. Needs to be tested....

Got my hands on an RDC test Tool and was able to do more digging. Turns out there are 2 bits for data integrity just before temperature byte. Temperature looks...

There was a typo in copy paste of values....

I am thinking whether the serial number is excluded from parity since if it has error it will not be picked up at all

> The second check bit could be (odd)parity on even numbered bits. Count the `1`s with the format string `1b1x` and compare. This seems correct

Digging further in the error checking, it is almost certain that the second check bit (C2) is parity. The first check bit (C1) seems to be affected by the actual...
