Why is no power supplied when I press the power switch on my JRC Receiver?
- R
  Ryan WoodAug 19, 2025
  There could be several reasons why your JRC Receiver isn't powering on. It may be due to a lack of power distribution from the inboard distribution panel, in which case you should supply power from the distribution panel. Another cause may be incorrect wiring or voltage from the power supply unit or NCR-333; check the wiring and output voltage. The power unit itself might be out of range and need replacement. Blown fuses in the Power Supply Unit (Option) could also be the culprit; check the wiring and replace the fuses. A broken power supply cable or controller switch could also prevent power-on; replace the power supply cable or the CMD-953 circuit board, respectively.

Why can't sensor data (external GPS, gyro, and rate-of-turn) be loaded on my JRC NCR-333 Receiver?
- D
  Daniel Stone DVMAug 21, 2025
  The issue might stem from several factors. First, verify the polarity of the serial cable and ensure it's correctly connected. Next, confirm that the interface between the sensor and NCR-333 is properly established. Also, ensure that the sensor generates a sentence supported by the NCR-333, checking both the output command and version. Another potential cause is a mismatch in the serial format (baud rate, etc.) between the sensor and the controller's settings; double-check the sensor's serial format. Lastly, the sensor itself (GPS, gyro, rate-of-turn indicator) might be malfunctioning, necessitating replacement.

Why is no NAVTEX message received on my JRC Receiver?
- C
  Courtney EatonAug 26, 2025
  Possible reasons include incorrect polarity or connection of the antenna cable; ensure the polarity is correct. The receiving station or message type may not be selected correctly. The NAVTEX antenna (NAW-333) could be damaged, requiring replacement. Also, the alarm number 004 could appear, indicating that the internal receiver 1, 2, or 3 is broken, requiring replacement of the CMN-2333.

  If the JRC Receiver doesn't power on when you press the power switch, several issues could be the cause. First, ensure that power is being distributed from the inboard distribution panel. If not, supply power from there. Next, check the wiring of the power supply unit or NCR-333 to make sure it's correct. The power unit may be supplying power that is out of the acceptable range, in which case, replace the power unit. Also, examine the fuses in the Power Supply Unit; if they are blown, check the wiring and replace the fuses. A broken power supply cable can also be the culprit, so replace it if necessary. Lastly, the controller switch itself might be broken, requiring replacement of the CMD-953 circuit board.

Why is sensor data not loading on my JRC NCR-333?
- C
  Cindy RamirezSep 6, 2025
  If sensor data (external GPS, gyro, and rate-of-tum) cannot be loaded, it might be due to several reasons. First, check if the polarity of the serial cable is correct and properly connect it. Next, verify that the interface between the sensor and NCR-333 is correct before connecting. It's also possible that the sentence that the sensor generates is not supported by the NCR-333; in this case, check the output command and the version. Finally, ensure that the serial format (baud rate, etc.) meets the setting of the controller by checking the serial format of the sensor.
