Basic Hardware troubleshooting
No LED indications and the power LED off.
- Check Power Supply voltage levels and connection polarity
- If correct check fuse located inside the enclosure
- Else call service

Power LED is on but no transmission is achieved
- Check if instrument is transmitting data
- If yes check listener’s port polarity
- Else call service

Charting system sends through RS-232 or Ethernet interface data to autopilot and there is no reception from my autopilot.
- Check configuration of the physical or virtual serial port of the computer to follow the 4.800/8/N/1 standards
- Check if signal from the autopilot port is correctly applied to the autopilot
- Else call service
