  • Page 11: Communication Format

    RS-232C Communication and USB Communication: Communication Format Communication Format Among transmitted data are commands such as “Request to Send” other than measurement data. In a sequence of transmission of measurement data from the LM to the computer, the computer transmits “Send Data command” to the LM, and the LM receives the command and sends “measurement data”. The software on the computer reads the received data strings according to the format information and then performs necessary processing (for example, display of data on the screen or storage of data on disks).

  • Page 12: Command Format

    RS-232C Communication and USB Communication: Communication Format 2.2.1 Command Format The commands (control character string) that are transmittable from and receivable by the LM are described below. These commands reciprocally control the LM and computer to make them transmit and receive data.
