How to integrate the Vaisala WXT510/520/530 and the Septentrio PolaRx5 (Web User Interface)


Configuring the Vaisala WXT510/520/530 Weather Transmitter

There are two ways to configure the Vaisala WXT510/520 Weather Transmitter:

    1. Use the Vaisala configuration software and service cable; load the UNAVCO configuration file located at:
      /questions/306/Vaisala+WTX-510%7B47%7D520+config+file+ .


  1. Use hyper terminal (or any other terminal emulation program) to configure the Vaisala WXT510/520 manually.

To configure the Vaisala using a terminal emulation program:

    1. Connect to the Vaisala using the following settings:

      • Baud: 19200

      • Parity: None

      • Flow Control: None

      • Edit the hyper terminal ASCII settings:

        • check box for "send line ends for line feed"

        • check box for "Echo typed characters locally"

        • check box for "Append line feed to incoming line ends"

    2. With the terminal connection established, power up the Vaisala. You should get a "0X0, start" message.

    3. Use the following commands to configure the WXT510/520:

      • 0XU,M=Q,C=2   (This should set the WXT510 to NMEA polled, RS232 communication)

      • 0TU,R=&11010000,I=180,P=B,T=C   (This should set the pressure units to bar and temperature to Celsius)

      • 0RU,R=&10000000U=M,Z=A   (This sets the precipitation units to mm/hr and counter reset)

      • 0WU,R=&01001000 (These next two commands  sets wind averaging, units, and output values)

      • 0WU, I=180,A=180,U=M,F=1 

      • 0SU,R=&00000000   (This removes the system status elements from the output values)

      • 0XU,M=P (to change the communication protocol back to ASCII)


  1. Verify the Vaisala is enabled:

Note: If using a WXT530, you must update the receiver firmware to 5.4.0

Using teqc to extract met records

Use the following command to create a met file:

teqc +met <filename>.met -M.obs pr+td+hr+ws+wd+ri+hi <filename>.sbf  >  <filename>.obs

where <filename>.sbf is the binary file that you pulled from the receiver,


<filename>.met is the ASCII file that contains the extracted met data,


<filename>.obs is the RINEX observation file extracted from the SBF file.
