ACTISENSE DATA SHEET Actisense NMEA Opto-Isolator Cables For an easy, safe and low-cost connection from an NMEA system to a PC / laptop, Actisense™ provides two variants of its PC Interface cable. Both allow a standard RS232 9-pin serial port to be connected to any NMEA 0183 marine bus link. Actisense™ PC-OPTO-1 cable The PC-OPTO-1 is a bi-directional NMEA 0183 to RS232 interface cable. It utilises full opto-isolation to protect the PC input and “tranzorb” protection for the PC output, providing comprehensive isolation of expensive PC hardware when connecting to an NMEA 0183 bus that may have picked up potentially hazardous voltages around the electrically noisy environment of a boat. Designed for general-purpose PC protection. each interface takes all necessary power from the PC port. Simple installation requires wiring the open end to the NMEA bus, and plugging the D-type connector into the PC. The NMEA data will then be available to the computer via its serial port. Actisense™ PC-OPTO-2 Cable As an enhancement for professional installations, the Actisense NMEA opto isolator cable is also available with a fully shielded cable and plug-case. This device, part number PC-OPTO-2, offers a complete solution for system builders that require all components to be shielded (particularly in noisy and/or commercial environments).
