OPTO-4 SERIAL OPTO ISOLATOR
●Isolate an RS232 (PC) port to protect against ground loops.
■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 utilises 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 bi-directional isolation in a USB to RS422 (NMEA 0183) form.
■The Actisense design integrates an over-moulded 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.
■Note: Connecting an external power supply may create a ground loop between the PC port and the supply. Check that the supply ground is at the same potential as the PC ground before connecting.
■Please refer to the Quick Start Guide for detailed wiring instructions, including how to use an external power supply.
