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...

The NMEA have updated the NMEA 0183 specification to ensure a consistent naming convention is used for labelling ports. The designation follows the same rules as used for Rx and Tx labelling but uses the descriptions’ Talker’ and ‘Listener’...

Yes, the OPTO-4 is a direct replacement for the PC-OPTO-3. The functionality is the same, please see the data sheet for the physical differences on the OPTO-4 downloads page...

Yes, simply connect the OPTO-4 female 9 pin connector to the male 9 pin connector of the USB to Serial Cable. The OPTO-4 will continue to provide isolation between the NMEA 0183 Talker and the PC. The USB to serial converter must support...

This is possible when connecting the wire ends together, but not when connecting the DB9 connectors together. Connecting the DB9 9 pin connectors together will remove the isolation, connecting the ground of both devices together...

The RS232 end is a female 9-pin D-Sub DB9 connector following the standard 9-pin RS232 pin out specification...

Yes, but you will need to provide power to the 9 pin connector (DB9) independently. Instructions for this are explained in the Quick Start Guide on the OPTO-4 downloads page...
