NMEA 2000 Electrical Diagnostics Monitoring
This device continually monitors the NMEA 2000 network signals Net-H (CAN_H), Net-L (CAN_L) and Net-S (supply voltage).
Applications include:
• Fault detection – such as CAN Wiring faults, CAN PCB faults, CAN Connector faults
• Wiring aging – trends of CAN voltages can be measured and if looked at over a longer period of time since installation. Trends may indicate degradation.
Features:
• CAN_H, CAN_L and differential voltage measurement on a per device basis
• Net-S – 12v supply voltage monitoring
• CAN error frame diagnostics
• Recording over longer term to analyse longer term trends (using SD-card)
Data supported and transmitted over NMEA 2000:
• All mandatory NMEA 2000 PGNs
• Proprietary Voltage Diagnostic – Offending Device Src Add, Fault Type
• NMEA 2000 Alerts
Availability:
• Full NMEA 2000 device in ECU casing and NMEA 2000 connector ready for white labelling
• PCB ready for integration into customer device via serial connection
• Windows application for displaying CAN ID or source address based data
