How to integrate the Vaisala WXT510/520 and the Trimble NetRS/NetR9

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+.

  2. OR

  3. 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)
  4.  

  5. Verify the Vaisala is enabled:

    • Issue a "0R0" command.

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

      0R0,Dm=076D,Sm=0.1M,Ta=24.4C,Ua=20.9P,Pa=0.8429B,Rc=0.00M,Hc=0.0M

      where:

      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 NetRS/NetR9

Configure the NetRS as follows:

  • I/O Configuration

    • Serial Port 2 Configuration

      • Service: Met-Tilt

        Baud: 19200
        Parity: None
        Flow Control: None

        Parameters for Met-Tilt mode:

        Command 0R0
        Schedule set to desired sample interval

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.dat > $filename.obs

where $filename.dat is the file you’ve created using the .T00 file you pulled from the receiver.

Alternatively, if you are collecting BNX data, use:

teqc +met $filename.met -M.obs pr+td+hr+ws+wd+ri+hi -binex  $filename.BNX > $filename.obs
