Troubleshooting the YoNav Server

What if the data does not change - that is, what if the connections are not working?

Check hardware connections

Check the connectors first. Are your cables all connected? Is the cable from the sensor(s) to the serial port(s) snug?

Check hardware

Are the sensors actually working - are they generating data and it is not getting through to the PC. Or are the sensors simply not working?

One way to independently verify the cabling and hardware interface is to use the Windows Terminal program to look at the input on the serial port in question. Do this by choosing, from the Start menu, the Run option. Enter terminal.exe to run the Terminal program.

Check software

Have you configured the YoNav Server correctly? (Check the settings on the Configuration page.)

In the second dialog box, at least one item in each dialog box must be highlighted. If you are not sure, from the Edit menu, choose Configure Vessel Tracking Properties, click to highlight all four and click OK.

Are your cables connected to the correct serial ports? If you have assigned a GPS receiver to serial port 2, verify that is the port that is being used. Using PC’s with multiple serial ports can be confusing at times.

Use the Test button on the Device Set Up screen to view data coming in and out of YoNav. (See the Configuration page for more details on this button.)

If the data looks correct in the test dialog, from the Edit menu, choose Configure Vessel Tracking Properties (as described on the Configuration page).

If no data appears in the test dialog, it is most likely a cabling or device problem.
