If NMEA input signals are listed in the NMEA input screen but not accepted by the DL850, it could be due to DL850 initialization issues. Cycle the DL850 power or perform a 'factory reset' after the NMEA connection is established. It could also be due to an irregular message mnemonic. In this case, check the remote (talker) setup.
What causes the rotary encoder to malfunction in Skipper Marine Equipment?
A malfunctioning rotary encoder could be due to a defective encoder or interface. Replace the keyboard PCB in this case. It could also be a software problem, so recycle power or do a 'factory reset'.
What to do if panel buttons malfunction on Skipper Marine Equipment?
If the panel buttons are malfunctioning, it could be due to defective buttons or interface. Replace the keyboard PCB or I/O PCB. It could also be that one button is stuck. Check the key switch(es) or replace the keyboard PCB. Finally, it could be a software problem, so recycle power or do a 'factory reset'.
Why does my Skipper DL850 Marine Equipment show constantly wrong speeds or no speed?
If you are experiencing constantly wrong speeds or no speed, it could be due to wrong calibration. Check the calibration and recalibrate if necessary. It could also be a damaged sensor, which would require replacement.
What to do if there is no picture on the LCD screen of my Skipper DL850?
If there's no picture on the LCD screen, here's what you can check: * Ensure the system is receiving AC or DC power by checking the switches and fuses on the terminal board inside the DL850 cabinet. * The system might be in standby mode. Press any button on the panel to exit standby. * The screen contrast might be too low. Increase the contrast settings or replace the keyboard PCB. * The LCD module might be defective. In this case, replace the LCD module. * The voltages might be out of range, requiring replacement of the terminal board.
Why does the ambient temperature in the status screen of my Skipper DL850 show too high?
If the ambient temperature in the status screen shows too high, it could be due to obstructed air flow. Check installations for obstructions of vent holes. It could also be a defective fan, which would need to be replaced.
Why are NMEA output signals from my Skipper DL850 Marine Equipment not accepted by the remote system?
If NMEA output signals are not being accepted by the remote system, it is likely due to the remote (listener) setup. Verify the correct remote (listener) setup.
What causes analogue output malfunctions in Skipper Marine Equipment?
Analogue output malfunctions could be due to incorrect range settings. Verify the upper and lower limits in the status screen.
What causes pulse output malfunctions in Skipper DL850?
Pulse output malfunctions can be caused by incorrect pulse frequency settings. Verify the pulse settings in the status screen.
What could cause the status screen to show Transmit/Receive (TX RX) Noise on my Skipper DL850 Marine Equipment?
The 'Transmit/Receive (TX RX) Noise' message on the status screen could indicate a lock up of the transceiver micro controller due to overheat or a strong source of noise close to the transceiver unit. Check the environmental and noise conditions in the area. Note that the display cabinet will restart the process automatically.
