NMEA 2000® / USB gateway

Maretron's USB100 is a gateway for bridging computers to an NMEA network. This allows you to use PC based vessel monitoring and control software like Maretron's N2KView® or PC based navigation software. The gateway provides one simple connection between the network and the PC, which eliminates conventional multiplexers and the maze of wires usually associated with interfacing equipment to PCs.

Maretron supplies drivers for the following versions of Windows.

  • Windows XP (32-bit and 64-bit)
  • Windows Vista (32-bit and 64-bit)
  • Windows 7 (32-bit and 64-bit)
  • Windows 8 (32-bit and 64-bit)
  • Windows 10 (32-bit and 64-bit)
  • Windows 11 (64-bit)

Note: The supplied drivers do not work on PCs with the ARM Architecture, such as certain models of the Surface Tablets.

For older PC-based navigation software that requires receiving data in NMEA 0183 format, the USB100 automatically converts information from the NMEA 2000® network to NMEA 0183 sentences. You can continue benefiting from navigational and charting software that you already own while enjoying the many benefits of networked NMEA 2000® instruments.

Maretron's USB100 is engineered and manufactured to the highest standards (IEC 60945 Maritime Navigation and Radiocommunication Equipment). Its compact waterproof housing will provide years of reliable performance.
