Why is the [spotbeam/Inmarsat] traffic light red on my Seatex DPS (Windows XP)?

A DPS unit based on Windows XP will show a red traffic light on Spotbeam/Inmarsat link in the following situations:

The demodulator does not have lock to a correction satellite

  • Verify that the demodulator is configured to receive the correct correction satellite for your area of operation and that the signal strength is good

The demodulator is without (or has a wrong) subscription

  • Check that subscription is valid and verify that it has the correct subscription type

The demodulator is not configured to output shore based correction data on

  • Check that RTCM output is configured on the correct output port

There is miscommunication between demodulator and DPS unit

  • Check the control interface parameters on both the DPS and the demodulator. Serial communication must be set to identical baud rate, start bit, stop bit and parity. Network communication must be set to correct mode (unicast/multicast) and with the correct IP address and network port

Note: This is only valid for DPS units with a display based on the Windows XP operating system
