The Actisense PRO-NBF-1 is a Type-Approved NMEA 0183 buffer designed to safely distribute data from one NMEA 0183 talker to up to six NMEA 0183 listeners with full electrical isolation. This is the correct solution when a single trusted data source must feed multiple devices without signal loading, noise, or ground-loop risk.
NMEA 0183 talkers are not designed to drive multiple listeners directly. Attempts to “Y-split” or parallel inputs often result in marginal voltage levels, intermittent data dropouts, and unpredictable behavior under load. The PRO-NBF-1 eliminates these issues by providing six properly driven, isolated outputs—so each connected listener receives a clean, standards-compliant NMEA 0183 signal.
The PRO-NBF-1 uses pluggable screw terminal connectors for fast serviceable wiring and can be bulkhead mounted or DIN rail mounted (DIN kit optional). Front-panel LEDs provide quick confirmation of power and data activity for basic diagnostics.
