DMH-GC/HC	Optical Data Transmission Devices
	This device is high-speed type, data transmission device with 16 bits. This device is smaller size and lighter weight than old type. This device provides light-projecting amount adjuster and so it is easy to adjust the communication distance.

*1 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

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

*3 STROBE
ON when data is fixed.
