The OPTO-4 provides a safe and low cost way of connecting an NMEA 0183 system to a PC or any other device with a standard RS232 9-pin port. As a bi-directional NMEA 0183 to RS232 interface cable, the OPTO-4 utilizes OPTO-isolation to protect the PC input and spike protection for the PC output, providing comprehensive isolation of PC hardware when connecting to an NMEA 0183 bus.

If isolation in both directions is required, the Actisense USG-2 offers bidirectional isolation in a USB to RS422 (NMEA 0183) form.

The Actisense design integrates an over-molded case for excellent water resistance and a small footprint for installation into tight spaces.

The OPTO-4 takes power from the host RS232 signals including TX and the handshaking lines RTS and DTR, making the OPTO-4 suitable for most PC serial ports.

In systems that cannot provide power on the handshaking lines, e.g. serial devices with only Rx and Tx lines, a DC power supply can be used.

The Actisense OPTO-4 is a bi-directional NMEA 0183 (RS422) to RS232 interface cable which provides a safe method of connecting an NMEA 0183 system to a laptop PC or any device with a standard RS232 9-pin port. The isolation protects the connected device, so any potentially hazardous voltages on the NMEA 0183 bus do not cause damage to the PC hardware, offering the user complete peace of mind.

The OPTO-4 is particularly suited to 'noisy' or commercial environments, as it provides a complete solution for system builders who require all components to be shielded. As it is port-powered (from the PC), the OPTO-4 is quick and trouble-free to install.

The unique Actisense design integrates an over-moulded case for excellent water resistance and a small footprint to ease installation into tight spaces.
