Data transmission is made from the machine to be checked in
ASK format. The transmission rate is 9600bps. Data of 00H,
11H, 22H, 33H, 44H, 55H, 66H, 77H, 88H, 99H, AAH, BBH,
CCH, EEH, and FFH are transmitted.
The checker machine sends back the received data.
The machine to be checked compares the data sent back and
the data transmitted first. If both data are the same, it displays
"PASS !!," and if not the same, "ERROR !!."
