The A2K-SBN-2 ACTISENSE (Small Boat Network) is an expanded, self-contained 8-port NMEA 2000 hub engineered for vessels requiring higher device density in a compact space. By integrating an 8-way Micro-C drop port block, internal $120 Omega$ termination resistors, and an attached 3-meter fused power cable into a single overmoulded footprint, the A2K-SBN-2 ACTISENSE creates a complete, standalone NMEA 2000 backbone network in one rugged assembly.
