Description
Actisense USG-2 NMEA 0183 RS422 RS232 Gateway | Boat Supply Store
Reliably interface PCs with legacy marine data networks when PC-to-NMEA ground loops or system faults are a concern. The Actisense USG-2 converts a standard USB port into a bi-directional serial interface supporting NMEA 0183, RS422, and RS232 protocols up to 230400 bps. Its proprietary ISO-Drive™ output and OPTO-isolated input prevent damaging ground loops and protect sensitive PC components from voltage transients common in vessel electrical systems. This robust gateway is essential for integrating navigation software or diagnostic tools with onboard instruments on offshore powerboats or coastal sailboats.

Common Concerns Answered
What are the return policies for the Actisense USG-2?
The Actisense USG-2 cannot be returned to the original point of purchase. For any issues or warranty claims, please contact Actisense directly for manufacturer support.
Is the initial setup complicated?
While the physical connection is straightforward due to the pluggable connectors, users may need to pay careful attention to driver installation and serial port configuration. However, the advanced isolation features simplify setup by removing common ground loop concerns.
Is the USG-2 more expensive than standard adapters and is it worth it?
The USG-2 has a higher price point than generic USB-to-serial adapters due to its advanced ISO-Drive™ and OPTO-isolation technologies. This superior electrical isolation, coupled with robust IP67 protection, significantly enhances reliability and prevents damage to connected PCs and marine equipment, making it a critical investment for critical data systems.
Frequently Asked Questions
What is the primary function of the Actisense USG-2?
The primary function of the Actisense USG-2 is to convert a PC's USB port into a bi-directional serial gateway, enabling communication with NMEA 0183, RS422, and RS232 marine data networks.
How does the Actisense USG-2 protect my PC from damage?
The USG-2 protects your PC through its ISO-Drive™ output and OPTO-isolated input, which electrically isolate the PC from the marine network. This prevents ground loops and shields the PC from over voltage, ESD, and short circuit faults.
What NMEA standards does the USG-2 support?
The Actisense USG-2 supports NMEA 0183, as well as RS422 and RS232 serial communication protocols.
Can the USG-2 be used with RS232 devices?
Yes, the Actisense USG-2 is fully compatible with RS232 devices, in addition to NMEA 0183 and RS422.
What is ISO-Drive™ technology?
ISO-Drive™ is Actisense's proprietary output isolation technology designed to prevent ground loops and protect connected equipment by ensuring electrical isolation between the PC and the marine data network.
