  • Page 17: Handshaking

    Handshaking To use an serial interface for transferring data between this instrument and a computer, it is necessary to use certain procedures by mutual agreement to ensure the proper transfer of data. These procedures are called “handshaking.” Various handshaking systems are available depending on the computer to be used; the same handshaking system must be used for both the computer and this instrument.
  • Page 18 2.4 Handshaking 3 XON-RS • Transmission data control A software handshake status is established between the instrument and host computer. The instrument will stop a data transmission when an X-OFF signal is received from the host computer, and will resume transmission when the next X-ON signal is received.

  • Page 19: Matching The Data Format

    Matching the Data Format The serial interface of this instrument performs communications using start-stop synchronization. In start-stop synchronization, one character is transmitted at a time. Each character consists of a start bit, data bits, a parity bit and a stop bit. Refer to the figure below.
