[CA] [CA11] EV-1 Heading Sensor not Recognized

[Chuck - Raymarine - Moderator]

FluidDynamic,

As sounder modules and radar transducers are designed to communicate via Ethernet communications rather than SeaTalkng / NMEA 2000 communications, the operation state of these devices would not reflect the operational state of a system's SeaTalkng / NMEA 2000 backbone. As the devices on the backbone appear to be getting power, but neither the diagnostics features of the MFD or autopilot control head are listing the devices on the backbone (these should include the MFD, autopilot control head, EV-1, and ACU-150), there would appear to be a problem with one of the SeaTalkng networking components (unplug, re-seat, and secure with locking rings all backbone and spur cables), with a termination plug (measure resistance across its CAN_H & CAN_L pins for 120 Ohms), or within the one of the products. More information concerning troubleshooting a SeaTalkng / NMEA 2000 backbone can be found within the FAQ addressing this subject. Should you need onboard assistance, you may want to consider contacting a Certified Raymarine Installer near you.
