[CA] [CA11] Wonky reports on DS500X Fish Finder

Skip,

Regarding the temperature issue and per the prior response, the DS500X will display the temperature value which corresponds to the sensed resistance of the transducer's thermistor. This same temperature value will be transmitted by the NMEA 0183 output port of the DS500X ... i.e. one should expect no difference between the temperature displayed by the DS500X and the value included within the NMEA 0183 sentences transmitted by the DS500X. Per the prior response, fault isolation would be performed by checking the resistance of the transducer's thermistor and comparing it to the expected temperature. Should no fault be found with the transducer's thermistor, then the fault would be deemed to be rooted in the DS500X. Correction of this problem would then require replacement of the DS500X, as Raymarine can not longer supply parts and service for DS500X fishfinders.

Per the prior response, the speed problem may be fault isolated using the instructions provided within the previously referenced FAQ. Should no fault be found with the transducer's speed sensor, then the fault would be deemed to be rooted in the DS500X. Likewise, correction of this problem would then require replacement of the DS500X.

Finally, the prior response in the absence of an EDI transducer tester, fault isolation of problems associated with a depth sounding product is typically performed by testing the depth sounding product with another compatible transducer which was known to be operational. Should no fault be found with the transducer's depth sensor, then the fault would be deemed to be rooted in the DS500X. Likewise, correction of this problem would then require replacement of the DS500X.
