Description

The Actisense PRO-BUF-2 is an intelligent, RINA type approved NMEA 0183 buffer built for larger leisure vessels and commercial shipping. It takes data from a single source and distributes it as amplified, isolated streams across twelve outputs, so every listener on the network receives a clean signal at the correct voltage. Two OPTO-isolated inputs and twelve ISO-Drive isolated outputs give complete protection against ground loops, the leading cause of failure in NMEA 0183 systems.

Alongside the NMEA 0183 ports the PRO-BUF-2 offers a bi-directional isolated serial port and an Ethernet port, allowing NMEA 0183 data to be streamed over a network and the unit to be configured through any web browser regardless of operating system. Predefined modes are selected simply by hard-wiring the mode inputs, while User Configuration Mode unlocks advanced sentence filtering, routing and automatic baud rate matching.

Housed in rugged 316 stainless steel with two-part pluggable screw terminals, an alarm relay and diagnostic LEDs, the PRO-BUF-2 mounts to a bulkhead or DIN rail and is ready to install straight out of the box.

How many devices can the PRO-BUF-2 drive from one source?
The PRO-BUF-2 takes data from a single source and buffers it into twelve identical, amplified and isolated NMEA 0183 outputs, so up to twelve listeners can each receive a clean signal at the correct voltage level.
Does the PRO-BUF-2 need a PC to configure?
No. Basic modes of operation are selected simply by hard-wiring the mode inputs. For full customisation the web-based configuration tool is accessed through the Ethernet port using any web browser, so there are no operating system compatibility issues.
Is the PRO-BUF-2 type approved for commercial vessels?
Yes. The PRO-BUF-2 is RINA type approved and meets IEC 60945, DNVGL-CG-0339 and IACS UR E10 requirements, making it suitable for commercial shipping and class or type installations.
