How to fix NORBIT Industrial Equipment when there is no timing in the sonar or GUI timing line is red?
- JJessica MirandaAug 27, 2025
If there is no timing in the NORBIT Industrial Equipment sonar or the GUI timing line is red: * Check the pins on the cable and SIU. If a pin is bent, VERY gently bend it back. *This may result in damage, so do so at own liability* * Go to INS Tools > Sky Plot and check that satellites are detected on both GNSS antennas. * Check that the PPS LED on the SIU is blinking at 1Hz. * If satellites are detected but the LED is not blinking at 1Hz, open POSView and check COM4 output to verify that it is configured to output NMEA ZDA at 1Hz, 9600 baud.
