Technical characteristics:
1.    Sensor inputs (shapes in Canon 25 pin)
        - frequency - 1Hz to 64кHz – 7 channels, mistake <1%; 
        - resistance - 2700 to 3400 Ώ , mistake < 0.01%;
        - parallel 8bit Gray’s code – 1 channel;
        - impulse counter – 0 to 3200 – 1 channel;
        - pressure sensor (aneroid, integrated) – input inside the body
        - RS 232 or RS 485 – (optional)
     2. Communication outputs (shaped it two Canon 9 pin)
        - RS 232 – 9600bps; 8bits/No parity/1stop bit;
        - RS 232:  9600bps or 1200bps; 8bits/No parity/1stop bit;
        - 7bits/Even/1stop bit, 7bits/Even/2stop bit;
        - USB option;
        - RS 485 option;
   3. Types of communication devices which cab be switched on to the communicational outputs
       - Radio modem
       - GSM modem
       - Telephone modem 
       - Notebook
   4. Functional possibilities
       - Time of averaging the measurements – 1 to 60min with step by 1min;
       - In OFF-line regime it could be set up a cycle of measurement in every 1 to 180min;
       - Calculating and memorizing speed dispersion and direction of the wind
       - Regulating the time and date of the Data Logger through RS input
       - When switched ON the Data Logger is automatically initialized by its last settings
       - Temperature range of work – 25oC to +65oC      
       - Power supply - DC 12 V, consummation <250 mA 
       - Additional, independent of electricity memory /Logger/ - if memorizing all data every hour the
         archive will be enough for 90 days.

DL MS&E-4 for professional meteorologic station
      DL MS&E-4 is designed to be compatible with the software for all older versions DL MS&E-3. Of course this will restrict its functions to those of DL MS&E-3
