Description Technical Specs Extended Information
 
Next generation Buffer that has 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. Version with 7 glands.

- Full galvanic Opto-isolation on NMEA 0183 input
- Full galvanic isolation on NMEA 0183 / ISO-Drive outputs
- Low current consumption
Features & Benefits
  • 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.
  • An Opto-isolated NMEA 0183 data input. A full galvanic Opto-isolated differential input that fully complies with the NMEA 0183 standard specification. This allows the input to work correctly with long cable runs, and/or in a noisy environment. This also allows the NBF-2 to offer up to 2500v of common mode voltage difference (between its input and outputs).
  • 6 ISO-Drive flexible outputs. Each ISO-Drive output is fully compatible with the RS422 (NMEA 0183), RS485 and RS232 connections on the NMEA listening devices the NBF-2 supplies data to, and offers total galvanic isolation of up to 1500v between the output and ground. The full-differential output ensures better quality communications and lower noise emissions on unshielded twisted pair cabling.
  • IP66/IP68 case and grommet design. A very robust polycarbonate case with a high waterproof certification. The small case size is ideal for space restrictive applications.
  • Extended warranty. Due to the significant protection improvements offered by the ISO-Drive outputs, all Actisense ISO-Drive products come with a extended length warranty of 3-years as standard.
  • Ground loop solution. The ISO-Drive outputs completely remove any problematic ground loops between the NMEA device connected to the input (talker), and all the NMEA devices connected to the 6 ISO-Drive outputs (listeners).
  • Large range of possible cable diameters. The cable grommets can accept any cable between 3.5 mm and 8 mm in diameter.
  • High quality angled screw terminals. The 'moving cage' type terminals make cable installation a simple and quick operation.
  • Wide battery input voltage range. To offer maximum compatibility, a battery supply of anywhere between 10 and 35 volts can be used.
  • Very low current consumption. Ideal for small vessels with small batteries.
