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

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum FluidDynamic,

It is recommended that the Spur Cable connecting the EV-1 CCU to the backbone be unplugged from both the backbone and EV-1 CCU. The sockets of the EV-1 and backbone network connector should be examined for any evidence of damage or corrosion. If a network connector socket shows signs of corrosion, then it should be replaced. If the socket of the EV-1 CCU shows signs of corrosion, then it should be sent to Raymarine’s Product Repair Center to be bench checked / serviced. The Spur Cable should also be inspected for damage or faulty splicing and replaced / addressed should a problem be identified with the Spur Cable. The Spur Cable should then be plugged back into the spur socket network connector and EV-1 CCU. The locking rings of the network connector and EV-1 CCU should then be rotated into the locked position and the system should be tested for detection of the EV-1 CCU within the MFD's Select Devices list.

Should the problem persist, then the ACU-150 should be unplugged from the backbone and then power to the entire marine electronics system should be cycled (OFF and then ON again). After doing so, then the system should be tested for detection of the EV-1 CCU within the MFD's Select Devices list. If not listed, then the EV-1 CCU should be sent to Raymarine’s Product Repair Center to be bench checked / serviced. If the EV-1 CCU is listed within the MFD's Select Devices list, then it is possible that the EV-1 CCU and ACU-150 may have mis-matched software. It would then be recommended that the software within the EV-1 be updated with the latest available Raymarine product software update. After doing so, then the ACU-150 should be reconnected to the backbone and if found to not be operating with the latest available software, then its software should also be updated. Please note that any updates to an Evolution autopilot EV-1/EV-2 CCU or ACU should then be followed by the actions specified within the FAQ found Raymarine’s web sitehere.
