[CA] [CA11] Problem updating HD Radar Software

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum JaRod,

Raymarine has produced no end user software updates for Digital radomes, HD Digital radomes, HD Open Array pedestals, or SuperHD open array pedestals. All software for these products is installed at the manufacturing or Repair Centers. Any such updates would have been associated with the replacement of a hardware component within the radar transducer which in turn required software specific to its use. Any suggestion by the software update process to update the software within one of these radomes should be ignored and the radar transducer should not be selected to be updated.

When the circuit for Digital radomes, HD Digital radomes, HD Open Array pedestals, or SuperHD open array pedestals remains powered ON while the system's MFDs are switched OFF, then the radar transducer will go into sleep mode after approximately ten minutes of communications loss with the system's MFDs. A has been indicated within this Forum, it is considered to be a best installation practice that radar transducers be powered from a dedicated switched power circuit which may be switched ON/OFF to awaken the radar transducer from sleep mode. As you have suggested, switching the MFD OFF would have no effect upon awaking the radar transducer from sleep mode. Later changes to the radar circuitry, most commonly within its I/O processor board, have made such occurrences of not awakening from sleep mode less common.

In summary, if the radar transducer awakens from sleep mode when the circuit supplying power to it has been cycled OFF and then ON again ... and the system's MFDs either remain ON or have been switched ON within approximately ten minutes of the radar transducer having been switched ON, then the system would be considered to be operating as designed. However, should the MFD not recognize the radar transducer after having cycled power to it, then it would be recommended that the troubleshooting and actions specified within the FAQ found here be exercised.
