Multiple Choice

The maximum voltage drop for an NMEA 2000 network powered from the battery is:

Explanation:
In an NMEA 2000 network powered from a battery, the voltage seen by every node must stay within the device’s operating range despite losses in cables, connectors, and terminations as current flows to all devices. The maximum allowable drop from the battery to the farthest node is set to ensure this margin remains intact under real-world conditions. The figure of about 1.17 volts is used because it provides enough headroom so that even with worst‑case cabling resistance and multiple devices drawing current, the distant nodes still operate reliably without dipping toward the lower limit of the device’s supply range. The other options either underestimate the practical losses (risking undervoltage on the far end) or overestimate them (not leaving enough margin for battery sag and connections).
