Sharing NMEA 0183 data with a PC

Last Updated: Sep 29, 2016 11:12AM BST
 Connecting NMEA 0183 devices directly to a PC without isolation is not recommended as this can cause ground loops which will damage your PC and your NMEA 0183 devices.  You may be interested in an Actisense USG-2 which provides isolation on the input and output, keeping your devices safe from ground loops.  The USG-2 also has a USB lead, making connections to a PC quick and simple.

A slightly lower cost alternative that we recommend as an absolute minimum means of electrical protection when interfacing NMEA 0183 devices to a PC is the Actisense OPTO-4.  This will provide isolation to the PC's input but not the output.  If your PC does not have a serial port you will also require a USB to serial adaptor:
