Whilst the 6 outputs of the NBF-2 are capable of driving up to 60 NMEA 0183 instruments, to maintain the galvanic isolation between each of the NMEA devices, it is recommended to use only one NMEA device per NMEA output...

A DIN Rail mounting kit is available to order from Actisense. The kit is not supplied with the NBF-3-BAS. The kit is suitable for use with top hat rail, type EN 50 022 or G section rail, type EN 50 035...

Yes, but there are several things to consider; firstly, each NBF-3 Talker port can drive up to 20mA. Check the sum of currents for all the NMEA Listener devices does not exceed 20mA. As a guide, the NMEA 0183 specification states that an...

There is only one variant of the NBF-3. If you are interested in a special OEM variant, please contact Actisense support...

When connecting an NMEA Talker device to the NBF-3 Listener port, it is possible to also power the NMEA Talker device from the NBF-3. This means only a single cable need be run between the NMEA Talker device and the NBF-3...

Yes, the NBF-3 will generate an identical copy of the electrical signal it receives on its input port to each of its output ports. The electrical signal must use RS422, RS485 or RS232 voltage levels for its ‘High’ and ‘Low’ data levels...

The NMEA 0183 specification, from version 2 (1996) onwards, requires a device’s Listener port to be isolated. Some NMEA 0183 devices however choose instead to follow version 1 of the specification which allowed for non-isolated inputs to be used...

Yes, the NBF-3 requires a supply between 10 to 35V DC and will use a maximum of 100mA at 12V DC (when all outputs are fully loaded with 100?). This does not include the current draw of the NBF-3 ‘Power Output’ that can be used to power...

The NBF-3 is a replacement for the NBF-2. The NBF-3 has the same functionality as the NBF-2 with the addition of a fused power output for powering the NMEA Talker device (that supplies the NBF-3 with data). The new case design allows...
