Description
USG-2 Isolated USB To Serial Gateway For Use w/NMEA0183, RS422 And RS232 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. Features: NMEA 0183, RS422 & RS232 compatible ISO-Drive™ technology Pluggable screwless connector with locking latch & strain relief Encapsulated electronics High retention USB socket Diagnostic & power LEDs Baud rates from 300 to 230400 bps Bulkhead mount, with optional DIN rail mount kit Pluggable screwless connector Inputs & outputs protected against over voltage, ESD & short circuits Simple installation Protects PC from damage Eliminates ground loops Technical Specifications: Power Supply (USB) Power Source - Bus powered Maximum Bus Current - 50mA NMEA 0183 Port – Talker & Listener Number of Listener/Input Ports - One isolated NMEA 0183 Listener Number of Talker/Output ports - One isolated NMEA 0183 Talker Compatibility - Fully NMEA 0183, RS422 & RS232 compatible.

Marine Navigation & Instruments — frequently asked
- What’s the difference between a chartplotter and a fishfinder?
- A chartplotter shows your GPS position on electronic charts for navigation. A fishfinder uses sonar to show what’s below the boat — depth, bottom structure, and fish. Many modern units combine both, and networked systems can share data across displays.
- Do I really need a VHF radio?
- For safety, yes. A VHF radio is the primary way to reach other vessels and the Coast Guard, and a DSC-equipped VHF connected to GPS can transmit your position in an emergency. It’s more reliable than a cell phone offshore and is the recognized standard for marine distress calls.
- What is NMEA 2000 and do I need it?
- NMEA 2000 is a standard network that lets marine electronics — chartplotter, sonar, autopilot, sensors, engine data — share information over a single backbone. It’s not required for a simple setup, but it makes multi-device systems far easier to expand and integrate.
