USG-2

Description
Advanced technology for safe, reliable and simple connection of your NMEA 0183, RS422 and RS232 devices to your PC’s USB port.
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-DriveTM 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 high quality, shielded USB lead included with the USG-2 makes connection to a PC simple while providing a high level of water protection when connected to the custom designed USB socket.
The pluggable screwless connector makes installation quick and easy, and the specifically designed DIN rail mount option ensures a reliable secure bulkhead mount for the USG-2.
Multiple LEDs make diagnosing connection issues quick and easy. The blue power LED Illuminates solid blue when the USB driver has successfully loaded and the USG-2 is powered, while a green (receive) LED and an orange (transmit) LED indicate whether data is present.

Benefits of the USG-2:
Inputs & outputs protected against over voltage, ESD & short circuits. Simple installation. Protects PC from damage.Eliminates ground loops. Features of the USG-2:

The USG-1 provides comprehensive isolation of the expensive PC hardware when connecting to an NMEA 0183 (RS422) bus that may have picked up potentially hazardous voltages around the electrically noisy environment of a vessel or factory, and makes installation simple due to the isolation of the PC ground from the NMEA 0183 data network ground, often the biggest cause of data errors and one of the biggest safety hazards in any electronic installation.
No external power supply is required as the cable takes all necessary power from the USB port. Simple installation using plug & play USB drivers supplied on CD allows the PC to start sending and receiving data to the NMEA 0183 data network within minutes of installation
