*1 MODE input
This is to choose transmission/reception mode when standing by
*Transmission stand-by mode by opened between mode and I/O COM
*Reception stand-by mode by short-circuited between mode and I/O COM
Note) If one side is set to transmission stand-by mode, other one should be set to reception standby mode.

*2 SELECT input
This is to stop transmission/reception optionally by outer signal
*Operating by opened between select and I/O COM
*Stopping by short-circuited between select and I/O COM

*3 GO output
This is to check correct optical single
*ON when receiving correct optical axis
*OFF when interrupting optical axis(Not-receiving)

*4 Strobe
It is getting ON when data is fixed.

Note) The connector attached can't be used as relay terminal.
