Description
Transfer data from an NMEA 2000 backbone to any device (e.g laptop, tablet or smartphone) connected to the W2K-2 via Wi-Fi and additionally convert this data to NMEA 0183 using Actisense’s renowned conversion engine.
OPTO-3 NMEA TO RS232 OPTO-ISOLATOR
The OPTO-3 is no longer in production. Please see the current OPTO-4 for the most advanced serial adaptor cable.
The Actisense PC-OPTO-3 is particularly suited to ‘noisy’ and/or commercial environments as it provides a complete solution for system builders who require all components to be shielded.
The PC-OPTO-3 features as standard, a fully shielded case and cable, making it completely reliable.
The easy, safe and low-cost way to connect an NMEA 0183 system to any device with a standard RS232 9-pin port, e.g. a laptop PC. The PC-OPTO-3 is a bi-directional NMEA 0183 (RS422) to RS232 interface cable. The Opto-isolation protects the connected device, offering complete peace of mind.
Port-powered (from the PC), the PC-OPTO-3 makes installation quick and trouble-free.
