Overview
-> It is 5 times faster than DMS series and this device can communicate more data in specific time.
Nổi Bậc
DMH-GB/HB
This device is high-speed type, data transmission device.
The transmission time is 7ms which is 5 times faster than the normal 8-bit DM series.
So it’s possible to transfer and receive more data within limited time.

*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.
