Just some more info,
in the protocol manual it says:
The reader communicates with host (MCU?MPU?Controller) using serial communication interface RS232 or
RS485 and complete corresponding operation according to the host command. The communication parameter is
57600bps 1 start bit, 8 data bits, 1 stop bit without parity check bit. In the process of serial communication, the
least significant bit of one byte is transmitted first and the least significant byte of command data sequence is
transmitted first.
But i cant find any mention of what that starting bit will be.
im so 
i dont know what is going on.
Really hoping someone has some good guesses?
