Actisense A2K-SBN-2 8-Way NMEA 2000 Boat Network
Build a compact NMEA 2000 network for up to eight devices with the Actisense A2K-SBN-2. Eight drops, two internal120Ω termination resistors and an attached3m power lead reduce the separate components needed. The network cannot be extended beyond eight devices.
Fitting
Plan the complete device count before selecting this unit. It is a self-contained terminated network, not an ordinary eight-port extension to an existing backbone. Follow the power and drop-length limits in the manual.
Maintenance
Inspect connectors and strain relief, keep seals correctly fitted and disconnect power before wiring work. Where firmware applies, use the manufacturer update procedure for this model.
FAQ
Can it be expanded beyond eight devices? — No. Actisense specifies a self-contained network for up to eight devices. Choose another backbone layout when more devices are needed.
Do I add two external terminators? — The SBN-2 already contains two120Ω termination resistors. Follow its standalone-network wiring instructions.
Are device drop cables included? — The unit has an attached3m power lead. Choose separate device drop cables of the required lengths.
