What is the NBF-3 power output for?
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, reducing installation time and cost. The NBF-3 ‘Power Output’connection has a self-resettable fuse providing up to 500mA to the NMEA Talker device at the voltage supplied to the NBF-3. Please refer to the specifications in the User Manual for more detail.
