Interface
Q	Do I need to connect all the 50 pins of the PIO interface?
A1	You do not need to connect all of them.
	For checking the connection, click here.
Q	The "REMOTE" or "READY" signal of the PIO interface sometimes turns off.
A1	Is the "RESET" of the PIO interface on? (including the signal by noise) When a transistor is the contact of a sequencer, the interface is more affected by noise compared to the relay contact because of leakage current, and the “Reset signal” may turn on.
Q	Marking does not start even if the "Marking start signal" is output from the PIO interface.
A1	Command “Marking start” after checking that the “BUSY” of the PIO interface is off.
Q	I performed settings of data through the serial interface, but no answer comes back from the marking machine. (Answer: "End of operation signal" of the 1FH or PIO interface)
A1	The marking machine determines the end of command data sent through the serial interface by the CR code (0DH), so if the CR code is not sent, it does not return an answer.
