The A2K-SBN-1 ACTISENSE (Small Boat Network) is a compact, self-contained NMEA 2000 hub designed specifically for small vessels, ribs, center consoles, and compact helm stations. By integrating a 4-way Micro-C junction block, internal $120 Omega$ termination resistors, and an attached 3-meter fused power cable into a single overmoulded enclosure, the A2K-SBN-1 ACTISENSE creates a complete, standalone NMEA 2000 network footprint in a single device.
