Isolate an RS232 (PC) 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.
