| Connect your data network to your PC USB
port with full electrical isolation... |
The Actisense™ USG-1 interface is an easy, safe and
low-cost method of connecting a marine NMEA 0183 system to a USB equipped
PC. Whilst protecting the most vital and expensive devices in the NMEA 0183
system, it also creates a virtual serial port that allows connection to an
NMEA 0183 (RS422) marine bus link.
Total galvanic isolation is assured using
an ISO-Drive output and the use of the trusted Actisense OPTO isolated input
circuitry.
The ISO-Drive output offers total galvanic isolation from the input and can "float" safely
up to 1500 VDC from ground. Its sophisticated circuitry is 100% compatible
with the NMEA 0183 RS422, industrial RS485 and single-ended PC RS232 "COM" ports.
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.
