9.7 Thermal camera troubleshootingProblems with the thermal camera and their possible causes and solutions are described here.Problem Possible causes Possible solutionsCamera is in Standby mode. The camera will not display video if it is in Standby mode.Use the camera controls (either the thermal cameraapplication or JCU) to “wake” the camera from standby.Problem with the thermalcamera video connections.• Check thermal camera video cables are sound andproperly connected.• Ensure that the video is connected into video input 1 atthe multifunction display or GVM.• Ensure that the correct video input is selected at thedisplay.Video not displayed.Problem with power supply tothe camera or JCU (if used asthe primary controller)• Check the power connections to the camera and JCU /PoE injector (if used).• Ensure that the power switch / breaker is on.• Check the fuse / breaker state.Cannot control thermal camerafrom Raymarine display orkeyboard.Thermal camera application isnot running.Ensure the thermal camera application is running on themultifunction display (as oppose to the video applicationwhich does not have camera controls).Check that the controller and thermal camera are correctlyconnected to the network. (Note: This may be a directconnection or via a Raymarine network switch.)Check the status of the Raymarine network switch.Network problem.Check that SeaTalkhs / RayNet cables are free fromdamage.Control conflict, e.g. causedby multiple users at differentstations.Ensure that no other controllers are in use at the sametime.Check power / network cabling to the controller and PoEinjector (PoE only used with optional Joystick Control Unit).Erratic or unresponsive controls.Problem with the controller.Check other controllers if available. If other controllersare operating this will eliminate the possibility of a morefundamental camera fault.Camera is not a dual payloadmodel.Only “dual payload” (dual lens) thermal cameras supportVIS / IR switching.Cannot switch between thermaland visible (VIS / IR) videoimage . VIS / IR cable not connected. Ensure that the VIS / IR cable is connected from thecamera to the Raymarine system. (The IR-only cable doesnot support switching).Poor quality or faulty videocable.Ensure that the video cable is no longer than necessary.The longer the cable is (or the smaller the wire gauge/ thickness), the more severe the losses become. Useonly high quality shielded cable suitable for a marineenvironment.Noisy image.Cable is picking upelectromagnetic interference(EMI) from another device.• Ensure you are using a high quality shielded cable.• Ensure proper cable separation, for example do notrun data and power cables in close proximity with eachother.Troubleshooting 115
