NBF-2: NMEA Buffer

World first: The power to drive up to six NMEA devices, with the safety of total input and output isolation, for total peace of mind. 

Next generation Buffer with full isolation on its input and all 6 outputs. Using the ISO-Drive Actisense technology, ground loops are now a thing of the past. Creating a robust and totally isolated NMEA system is now possible with the power of the NMEA Buffer 2. 

• Full galvanic Opto-isolation on NMEA 0183 input
• Full galvanic isolation on NMEA 0183 / ISO-Drive outputs
• Low current consumption

The Actisense® NMEA Buffer module is the best solution for buffering weak NMEA sources, allowing NMEA devices to be driven, such as chart plotters, radars, and/or an on-board PC / Laptop.

The very latest Actisense® ISO-Drive technology has been added to the NBF-2 so that now each output is separately isolated from each other and from the power supply, making this a world first at this price point and the safest buffer on the market.

The NBF-2 Buffer is required wherever an NMEA source cannot provide sufficient power to drive all the equipment that requires the NMEA data it supplies. It is also ideal for safely interfacing an on board PC to all the NMEA equipment on board a vessel, while providing total Opto-isolation between every device.

Due to the ISO-Drive output, the buffer may also be used where a ground loop problem needs solving, and means that it is not necessary to use supply isolators to achieve isolation between two data sources.

Designed for buffering data from all NMEA source types (RS422, RS485 and RS232), including direct connection to a PC RS232 output, this buffer produces an amplified copy on each of its 6 ISO-Drive outputs.

Electrical spike protection is provided as standard on the buffer's input using full galvanic Opto-isolation to provide superior protection to the NMEA source device. The NBF-2 input exceeds all the requirements of the latest NMEA 0183 specification.

Simple to use, high quality screw connectors that are angled to allow easy access, make wiring up the NMEA Buffer a simple task.
