Adaptable NMEA 0183 Buffer with two OPTO-isolated inputs and twelve ISO-Drive isolated outputs, making ground loops a thing of the past and keeping devices safe from damage.

Introducing the Actisense® Professional NMEA 0183 Buffer (PRO-BUF-1), the first product in the new Actisense ‘PRO’ range. PRO-BUF-1 is reliable, robust and provides isolation on all inputs and outputs as standard. With two NMEA 0183 inputs, twelve NMEA 0183 outputs, a bi-directional serial port and an Ethernet port, the PRO-BUF-1 is a perfect solution for larger leisure vessels and commercial shipping.

The four pre-defined modes of operation are designed to suit the majority of NMEA 0183 systems making the PRO-BUF-1 ready to go ‘out of the box’ by simply hard-wiring the two mode inputs as required. For all other configurations, leaving the mode inputs floating selects the ‘User Configuration Mode’. The web browser based configuration tool allows full customisation of the PRO-BUF-1, and as the configuration tool is web based it is compatible across all popular Operating Systems. The PRO-BUF-1 supports a direct Ethernet connection to a PC without the need for a specialised Ethernet crossover cable.

To make installation quick and simple the PRO-BUF-1 features 2-part pluggable connectors that allow use of screw or screwless terminals, and a professional DIN rail mounting mechanism. Helpful LEDs indicate power, data in, data out and the alarm status to aid diagnostics.
