Power Requirements
Termination Requirements
Backbone: • Maximum length: 200m (656 ft) • Minimum length between T's: 0.5m • Cable type: Safiery NMEA 2000 Compliant Drop Cables: • Maximum length: 2m each • For longer lengths: Run longer ~ 20m cable with terminator at T piece at end
Network Power: • Voltage: 12V DC (9-16V range) • Current: 3A typical, 5A maximum • Insert Power towards cetre of backbone or network
Terminators: • Exactly 2 required (one at each end) • Resistance: 120Ω ± 6Ω • Male on one end, Female on other
Connector Types: • Safiery NMEA 2000 Compliant Micro-C (M12) 5-pin standard • Safiery Solid State and meteor Batteries have a Terminator inbuilt Which means place these at end of line in drawing above and do not user a separate terminator on that end.
