NMEA NBF-3 Buffer

Actisense NBF-2 NMEA BufferWorld first: The power to drive up to six NMEA devices, with the safety of total input and output isolation, for total peace of mind. 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-3 so that now each output is separately isolated from each other and from the power supply, making this a world first and the safest buffer on the market.

The NBF-3 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.

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.

NDC-4 NMEA Multiplexer

Actisense NDC-4 NMEA MultiplexerMultiplex or Autoswitch up to 5 NMEA devices to your PC, Chart-plotter, Radar, Autopilot and more, with NMEA 0183 HS compatibility and ISO-Drive. This Actisense NMEA Multiplexer / Combiner allows connection of up to five NMEA (National Marine Electronics Association) inputs, and multiplexes / combines or autoswitches them to its two fully isolated NMEA outputs.

This approach offers these major advantages:

Completely removes the need for isolated power supplies - as the NDC-4 creates a full 2500v isolation barrier between it's inputs and each of it's ISO-Drive outputs
Enables the vessel owner complete access to all NMEA data sources, instead of the standard one device
Any problematic or unwanted NMEA sentences can be filtered out / blocked, to help intelligently reduce the NMEA data to a manageable amount and prevent data loops
Each NMEA input device is Opto-isolated from all other NMEA device in the system
Significant reductions in installation cost (from reduced cable lengths and requiring only one NMEA cable to be routed around the bridge to supply the multiplexed NMEA data.

NGW-1 NMEA 1803 to NMEA 2000 Gateway

Actisense NGW-1 GatewayThe Actisense&trade. NMEA 2000 to NMEA 0183 Gateway is the easiest way to link between a boat's old and new data networks. The NGW-1 can convert NMEA 0183 data into NMEA 2000 data and vice-versa.

Using the advanced configuration software it is simple to set up which data items you want translated between the two buses.

The NGW-1 allows current NMEA 0183 equipment to be kept, or allows the latest NMEA 2000 equipment to be incorporated into the NMEA 0183 system. Once the single cable NMEA 2000 bus system has been installed, data from any node on the bus can be listened to by any other, including any NMEA 0183 instruments connected using an NGW-1.

The new Actisense NMEA Reader software utility can now be downloaded from this page. This utility allows the NGW-1 user to view and understand (in detail) the translated NMEA 0183 sentences output by an NGW-1 device directly, or via an Actisense USG-1.

The NMEA 2000 network acts like a bi-directional multiplexer, allowing all data sources to talk and listen to each other.
