PRO NMEA 0183 Buffer - 2 OPTO Inputs, 12 ISO-Drive Outputs, Serial Port, Ethernet Port, Pluggable Screw Terminal

Two OPTO-isolated inputs and twelve ISO-Drive™ isolated outputs. Offering device protection and excellent flexibility, all in one product - the Actisense® PRO-BUF-2, the intelligent, type-approved PRO range buffer.

The PRO-BUF-2 is rugged, with a stainless steel housing, and provides isolation on all inputs and outputs. With two NMEA 0183 inputs, twelve NMEA 0183 outputs, a bi-directional serial port, and an Ethernet port, the PRO-BUF-2 is a perfect solution for larger leisure vessels, commercial shipping, and is a great addition for systems that require type-approved devices.

The PRO-BUF-2 is designed to suit the majority of NMEA 0183 systems and is ready to go ‘out of the box’ by simply hard-wiring the two-mode inputs as required.

The Intelligent NMEA 0183 Buffer's manually configurable basic modes of operation include variations of buffer modes, intelligent auto-switch, and combine modes.

For all other configurations, leaving the mode inputs floating selects the ‘User Configuration Mode’. The web-based configuration tool allows full customisation of the PRO-BUF-2, and is compatible across all popular Operating Systems. Using the web-based configuration tool allows for fine-tuning of the data available on each output.

To make installation quick and simple, the PRO-BUF-2 features 2-part pluggable connectors that allow the use of screw terminals*, and a professional DIN Rail mounting system (DIN Rail not included). The device can also be mounted directly to the bulkhead.

Helpful LEDs indicate power, data in, data out, and the alarm status to aid diagnostics.

Data statistics and load indication via the web tool provide a real-time view of data.
