    • Maretron’s NBE100 (Network Bus Extender) allows you to extend the maximum node count, network trunk length and cumulative device’s drop lengths of any NMEA 2000® network
    • The NBE100 solves bus errors and other electrical issues caused by exceeding any of these limitations and makes design of large networks easier
    • NMEA 2000® networks have a maximum of (50) nodes allowed on a single network, a maximum network trunk length of 200m and a maximum cumulative device’s drop lengths of 78m
    • If you have a network that exceeds any of these specifications, you can simply extend the network trunk by inserting the NBE100, along with additional termination resistors
    • This will split the network into multiple electrical segments, each of which can have up to (50) nodes
      • These segments allow increase of nodes on the logical network
    • The NBE100 will transparently route NMEA 2000® messages between the multiple network segments, making them work as a single logical NMEA 2000® network
    • Advanced priority-based message routing ensures that higher-priority messages are always prioritized over lower-priority messages, enabling predictable and reliable network operation
