Checksum is calculated as XOR for all bytes from the first byte after STX up until and including ETX.
Data bytes have reverse bit order, i.e. bit7 = bit0, bit6 = bit1 etc. PowerMACS will respond to all telegrams
independent of Destination from XD.
Reading 5 integers at address 500 Writing 5 integers at address 0
