DMH-GC/HC

Optical Data Transmission DeviceParallel type

This device is high-speed type, data transmission device with 16 bits.

Overview

Features

-> 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.
