  • Page 17: Handshake Format Selection

    Handshake Format Selection In order to ensure proper data transfers between the recorder and the host computer via the RS-232- C interface, a mutual procedure is required for processing the electrical signals. Such a procedure is referred to as a ‘handshake’. Several handshake formats are available, with selection depending on the host computer being used.
  • Page 18 2.4 Handshake Format Selection XON-DTR • Transmission data control : A software handshake status is established between the recorder and the host computer. The recorder will stop a data transmission when an X-OFF signal is received from the host computer. The data transmission will be resumed when the next X-ON signal is received.

    App.1 Computing Equation DR130/DR230/DR240 can execute computations with the measured data of each input channel taken as a variable, and the results can be displayed/saved (functions available for use only when DR130/DR230/DR240 has the -M1 option) . The following operators can be used for computation. Basic operators Type Operator Example Description...

    App.1 Computing Equation Statistical operators within the group Type Operator Example Description Maximum value CLOG.MAX() CLOG.MAX(G01) Obtain the maximum value of the measured data of group G01. Minimum value CLOG.MIN() CLOG.MIN(G02) Obtain the minimum value of the measured data of group G02. Max-min value CLOG.P-P() CLOG.P-P(G03) Obtain the P-P value of the measured data of group G03.
  • Page 92 App.1 Computing Equation Units in computing equations In computations, measured data are handled as numbers without units. For example, if the measured data of channel 001 is “20 mV” and the measured data of channel 002 is “20 V”, the computed result of “001+002”...
