NMEA 0183 PC Opto-isolator cable, RS232 DB9 female, shielded (isolated to PC).
The Actisense opto isolator design integrates an over-moulded case for excellent water resistance and a small footprint for installation into tight spaces.
Use case
Older marine PC’s and certain NMEA 0183 instruments utilise a DB9 connection rather than a USB or differential RS-422 Port. The OPTO-4 can be used here to transfer NMEA 0183 data without having to worry about ground loops thanks to the opto-isolation technology. The OPTO is also powered from the RS-232 / serial port on a PC, making installation even easier.
*When isolation is required in both directions and/or the PC doesn’t have an RS232 port, the Actisense USG-2 offers bi-directional isolation in a USB to RS422 (NMEA 0183) form.
