NMEA 0183 PC OPTO-Isolator Cable, RS232 DB9 Female, Shielded (Isolated to PC)
Add isolation to an RS232 port to protect against ground loops. The OPTO-4 provides a safe and low cost way of connecting an RS422 (NMEA 0183) system to an RS232 (PC COM port) system, or any other device with a standard RS232 9-pin port.
The OPTO-4 provides comprehensive galvanic OPTO-isolation to protect the PC input/receiver, plus important spike suppression to improve the PC output/transmitter protection. Initially designed for systems wishing to receive NMEA 0183 data without the risk of ground loop damage, the flexible OPTO-4 can be used to interface any RS422 and standard RS232 connection, whilst powering itself from the RS232 port, making installation simple and very quick.
The Actisense opto isolator design integrates an over-molded case for excellent water resistance and a small footprint for installation into tight spaces.
Features:
- One RS422 OPTO-isolated input
- One RS422 (NMEA 0183) output
- Up to 115200 baud
- Port powered
- Shielded cable and case
- Protects PC input/receiver from damage
- Water resistant cable.
- Ruggedized over-molded case suitable for harsh environment
