The Actisense™ USG-1-485 interface is an easy, safe and low-cost method of connecting an industry standard RS485 / IEC 61162-2 half-duplex system to a USB equipped PC. Whilst protecting the most vital and expensive devices in the RS485 system, it also creates a virtual serial port that allows connection to an RS485 industrial bus link.

Total galvanic isolation is assured using the Actisense opto-isolated ISO-Drive transceiver circuitry.

The ISO-Drive transceiver offers total galvanic isolation from the input and can "float" safely up to 1500 VDC from ground. Its sophisticated circuitry is 100% compatible with industrial RS485 ports.

The USG-1 provides comprehensive isolation of the expensive PC hardware when connecting to an RS485 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 RS485 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 RS485 half-duplex data network within minutes of installation.
