How to integrate the Vaisala WXT510/520 and the Septentrio PolaRx5 (Command Line)


Configuring the Vaisala WXT510/520 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:
      http://kb.unavco.org/kb/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:

    • Issue a "0R0" command.

    • The met pack is set to output the following string:



      0R0 - the command that is sent
      Dm - wind direction, degrees
      Sm - wind speed, m/s
      Ta - temperature, degree C
      Ua - humidity, percent
      Pa - barometric pressure, Bar
      Rc - rainfall, mm/sampling period (reset at each measurement)
      Hc - hail, hits/sampling period (reset at each measurement)

Configuring the Septentrio PolaRx5

Configuring the PolaRx5 using a telnet connection

  • Connect to the receiver (default command port: 28784)

    • telnet ip_address port_number
  • Login to the receiver

    • login, username, password
  • Setup the serial port (in this example the met device is connected to COM2)

    • scs, COM2, baud19200, bits8, No, bit1, none
  • Enable a periodic ASCII command to be sent to the met device (%%CR and %%LF correctly terminate the '0R0' command sent the the device)

    • spe, COM2, A:0R0%%CR%%LF, min5
  • Enable the receiver to accept the met device's ASCII input

    • sdio, COM2, ASCIIIn
  • Add the ASCIIIn to the desired SBF logging stream

    • sso, Stream#, LOG#, +ASCIIIn,
  • Save the new configuration settings to Boot

    • eccf, Current, Boot

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.
