USG-2 USB to Serial Gateway
The USG-2 ensures safety and reliability when connecting a PC to your NMEA 0183 network.
The USG-2 converts a USB port into a bi-directional serial port suitable for connecting to a marine standard NMEA 0183 data bus.
It provides a far safer connection when compared to standard USB to serial converters.
Electrical isolation is provided by the ISO-Drive™ output and OPTO-isolated input making installation simple and free from ground loops.
The input uses the Actisense OPTO-isolation circuitry to protect any connected equipment from the most common system faults. The input can receive very low-level signals that are often too small to be received by a PC serial port.
The USG-2 is the safest way to connect a boat’s data network to an on-board PC.
