Free Space Optical Communication
 

3. Parallel Communication

16-bit CommunicationSOT-NP16 Series
 

Feature

Supports 16 bit transfer points
There are two types of communication range: 0 to 1 meter, and 0 to 3 meters. Choose the one suited to your application. The device can be switched between two-way and one-way communication via operation-mode switch input. Display lamps are installed on top of the unit, making it possible to determine at a glance whether it is inputting (red) or outputting (green).
