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.

Where To Buy

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.

  • USG-2

A USG-2 is the safest and most reliable method of connecting NMEA 0183 instruments to a PC. The device offers full isolation and protection for both the PC and the connected device.

Many marine applications utilise NMEA 0183 as the data format rather than NMEA 2000. A perfect example of this is OpenCPN, where the user needs to get GPS data into the application for an accurate location fix. The USG-2 makes this very easy by creating a Com Port on the PC for the USB connection, which can then be opened by the application at the same baud rate as the GPS (typically 4800 baud). The USG-2 is very simple and quick to wire up, saving time and money.  

The cheaper serial to USB converters on the market do not offer the same level of protection to the connected devices, meaning the USG-2 offers a much safer connection.
