BCC = XOR of values hatched

[Samset]

Hello,

[OK I fund the solution, it was dumb  ] now I cannot delete the post!

I was trying to communicate with a distance finder via RS485 (CD22M-35-485). The bytes must conform to the datagram. I would like to know what is meant by "BCC = XOR of values hatched" at the end. I know what XOR mean but not values hatched!?

For exemple: 02h ^ 52h ^ 40h ^ 06h ^ 03h  = gave me 15h not 0x14 from the documentation exemple, what's wrong?

Thank you

My guess is that they leave out the "STX" (1st) and "ETX" (last before BCC) values for the XORing and only use command and data.
0x52 ^ 0x40 ^ 0x06 = 0x14
0x57 ^ 0x00 ^ 0x04 = 0x53

Yes thank you, I realized right after sending this post. I thought "BCC = XOR of values hatched" was a bytes maniplation ...
