    1 OUTLINE 1 OUTLINE Communication Interface As an option, the SR23 Series supports two communication interfaces: RS-2323C and RS-485. Using these communication interfaces, you can set up or read various data from a personal computer. The RS-2323C and RS-485 communication interface are data communication standards determined by the EIA (Electronic Industries Alliance) of the United States.
  • Page 10 1 OUTLINE SHIMADEN standard protocol This is a SHIMADEN proprietary communication protocol. The table below shows the specifications of this protocol. Data length 7/8 bits Parity EVEN, ODD, NONE Stop bit 1/2 bits Communication address 01 to 98 Communication memory mode...

  • Page 11: Connecting The Controller To A Host Computer

    2 CONNECTING THE CONTROLLER TO A HOST COMPUTER CONNECTING THE CONTROLLER TO A HOST COMPUTER The SR23 Series controller is connected to the host computer by three lines, send data, receive data and signal ground. The following shows connection examples.
  • Page 12 2 CONNECTING THE CONTROLLER TO A HOST COMPUTER Host SR23 Controller １ ＋(13) －(14) SG(12) Controller ２ ＋(13) －(14) SG(12) Controller Ｎ ＋(13) －(14) SG(12) Terminator (120 Ω) About tri-state output control When the RS-485 interface is used, the connection becomes a multidrop connection. For this reason, to avoid conflict between send signals, the transmission output is held at high-impedance at all times during reception or when communication is not performed.

    (new start character). Communication Format The SR23 Series supports various protocols, and so various selections can be made by the communication format (control codes, BCC operation method) or communication data format (data bit length, parity, stop bit length).

  • Page 20: Outline Of Communication Format

    4 EXPLANATION OF SHIMADEN PROTOCOL Outline of communication format The formats of the communications commands sent from the master and the communication response formats sent from the slave comprise three blocks: basic format section I, text section and basic format section II.

  • Page 22 4 EXPLANATION OF SHIMADEN PROTOCOL Addition operation is performed from start character (1) through to text end character (12) in ASCII data 1-character (1-byte) units, and the two’s complement of the lower 1 byte of the operation result is taken.
  • Page 23 4 EXPLANATION OF SHIMADEN PROTOCOL j: End character (delimiter) [(15), (16): 1 digit or 2 digits/CR or CR LF] • Indicates the end of the communication message. • The following two types can be selected as the end character: (15), (16): CR (0DH) (LF is not appended by CR alone.)
