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:
   /questions/306/Vaisala+WTX-510%7B47%7D520+config+file+ .

OR

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,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 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,

and 

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

and 

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