4. Simultaneous Parallel/Serial Communication

16-points/32-points CommunicationSOT-NP16/32_708 Series
 
Feature

Supports simultaneous serial and parallel communication
This is a two-way data-transmission device that utilizes optics. Flip a switch to handle parallel and serial data simultaneously. 16- or 32-points parallel data transfer types are available. Maintenance is simple because it uses a connector for external connections. The optical transmission range is quite long, at 70 meters.
