Actisense USB to Serial Gateway USG-1 The Actisense USG-1 is the safest way to connect your boat's data network to an onboard PC. It simply converts a USB port into a serial port, suitable for connecting to a marine standard NMEA 0183 data bus. Its ISO-Drive output and OPTO input provide full isolation, making installation simple and free from ground loops. No risks of burning wires, circuits or causing damage to PC equipment. The output is separately isolated from the input (listener) circuit, and can “float” safely up to 1500VDC from ground. Its sophisticated circuitry is 100% compatible with both RS232 (single-ended) and NMEA 0183 (differential) drive systems. Electrical spike protection is provided on the listener input using an OPTO-Isolator to protect any connected equipment from most common system faults. Using a low cost USB to RS232 cable from a computer store risks expensive damage to the PC, as there is no isolation and also such a device may not provide either the drive current or the correct voltage levels for NMEA 0183 interfacing. Just connect the USG-1 and relax, knowing that Actisense has it secured. Uses • Create a safe serial port connection to an NMEA 0183 system that may be on a different power circuit from the PC • Connect two PCs together that are on different power circuits • Provide a fully compliant NMEA 0183 port from a USB port • Receive low level differential signals that are too small to be received by a PC serial port • Frees up PC serial / COM port for other uses Features • Full electrical isolation - safe against the number one marine electronic fault condition (ground loops) • Full USB compliance • Can connect to either PC COM port or marine NMEA 0183 interfaces • Up to 115.2 kbps data transfer rate
