Oops. The question was meant in regards to the connection of the Thies wind speed sensor. :-)
To be clear. For the Thies FC wind speed sensor, is it necessary to use some type of SCM card for connecting it? From the datasheets I read that the Thies has an output frequency of 1082 Hz at 50 m/s, while the Nr.40 has a maximum frequency of 125 Hz (about 65 Hz at 50 m/s). The RM Young Wind Monitor is specified to have 90 Hz at 8.8 m/s, (about 510 Hz at 50 m/s) and I see that there is a special SCM card for using it with the Symphonie dataloggers. In the Symphonie specs it says up to 2500 Hz is ok,
