Configuring the Instrument Connecting through the PCMCIA Slot. The GPS receiver can connect through the PCMCIA slot and emulate a serial port on COM4. The Teletype GPS WorldNavigator (product #1351) has been tested with the YBA250 application. Setting Up YBA250/GPS receiver communications To set up the GPS receiver to work with the YBA250: 1. Set your GPS receiver to regularly output NMEA sentences. 2. Connect the GPS receiver (by serial cable or through the PCMCIA slot) to the NetTek Analyzer platform. 3. In the YBA250 application, tap the Edit button and then the Save & Export tab. 4. Select the correct GPS receiver interface type (Serial or PCMCIA) from the GPS Receiver drop-down list. The YBA250 displays the latitude and longitude just to the right of the drop-down list box a short time after the GPS receiver sends the $GPRMC sentence. Tap the Refresh button to update the displayed coordinates. You can also view the latest GPS position in the Results Properties dialog box (File > Results Properties). When you open a saved results file, the Results Properties shows information about the results file, including the GPS position at the time the results file was saved. Troubleshooting Your GPS Receiver After you have selected the GPS receiver type in the Save & Export dialog box, a position should appear immediately to the right of the list box. Error Message: Invalid Position. If, after you select the GPS receiver type in the Save & Export dialog, the message “Invalid Position” appears, then the communication connection to the receiver has been successfully established, and the $GPRMC sentence is being successfully read from the receiver, but the position supplied in that sentence is not valid. In this case, check your GPS receiver to see if it does have a valid position, and, if not, refer to the GPS receiver documentation to resolve this problem. 2-62 YBA250 Antenna and Transmission Line Analyzer User Manual
Configuring the Instrument Error Message: Unable to Read Position Information If the instrument displays an error dialog indicating that the application was unable to read position information from the GPS receiver, do the following: Make sure the cable from the receiver to the serial port is connected and that the PCMCIA card is firmly seated. Ensure that the receiver is set to regularly output NMEA sentences. If you have purchased the vxHpc terminal emulator, you can view the NMEA sentences being sent. Open the vxHpc terminal emulator by tapping Start > Programs > Communication > vxHpc. To view the NMEA sentences being sent, you need to set up vxHpc to connect to the correct port: For a serial port GPS receiver, set up vxHpc to connect to COM1. For the Teletype WorldNavigator, set up vxHpc to connect to Teletype_1358 (for Y350C NetTek Analyzer Platforms) or COM4 (for Y400 NetTek Analyzer Platforms). Configure the serial port as follows: 4800 baud 8 data bits No parity 1stopbit No flow control Open the session. You should see NMEA sentences being sent the GPS receiver. If you do not see NMEA sentences, either the GPS receiver is not sending the sentences or the connection to the GPS receiver is not passing them (check the cables again). Refer to your GPS receiver documentation to find out how to output NMEA sentences regularly. YBA250 Antenna and Transmission Line Analyzer User Manual 2-63
