Actisense OPTO-4 NMEA 0183 Opto-Isolated Serial Adaptor Cable

Actisense OPTO-4 Serial Adaptor Cable

The Actisense OPTO-4 is a specialized marine-grade NMEA 0183 to RS232 Serial Adaptor Cable engineered to safely connect NMEA 0183 talkers/listeners directly to a standard PC RS232 serial port (DB9) or USB-to-serial converter. It provides an essential bi-directional interface for navigation software, chart plotters, radar systems, and vessel data logging equipment.

Designed with full galvanic isolation, the OPTO-4 protects connected computers and delicate marine electronics against dangerous ground loops, high voltage spikes, and common-mode noise. Powered directly from the host RS232 port signals, it operates without requiring an external DC power supply, making it a reliable plug-and-play solution for marine electronics integration.

Key Features

• Galvanic Opto-Isolation: Protects PC hardware from ground loop current flows, stray voltages, and transient spikes up to 2,500 V RMS.

• Port-Powered Operation: Draws operating power directly from the host RS232 port handshaking lines (DTR/RTS), eliminating external wiring.

• Bi-Directional Communication: Enables simultaneous NMEA 0183 data reception (listener) and transmission (talker).

• Flexible Cable Harness: Rugged, shielded multi-core cable housing color-coded bare wire leads for straightforward terminal block wiring.

• Universal NMEA 0183 Compatibility: Fully compatible with RS422 and RS232 NMEA 0183 signal levels at standard (4,800 baud) and high speeds (38,400 baud AIS).
