NBF-2 NMEA 0183 Buffer
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.
