    RS-232C COMMUNICATION Outline of RS-232C Communication To transmit data measured by the ARK-530A/510A to an external computer, the ARK-530A/510A comes equipped with an RS-232C interface. This manual provides the method of receiving the mea- surement data from the ARK-530A/510A through this interface.
  • Page 8 (RS-232C) D-sub 9P (female) DIN 8P Connect the ARK-530A/510A interface port and the serial communication port (RS-232C) of the external computer with the above interface cable (Model: OPIF-15). This interface cable allows the “71. I/F MODE” parameter to be set either to “Nidek” or “NCP10”.

  • Page 10 When the “I/F MODE” parameter is set to NCP10 The DTR/DSR control is not performed. The DTR signal of the ARK-530A/510A is constantly at a low state on a line. The DTR signal of the external computer does not affect the transmission under either condition.

  • Page 11: Data Format

    Command format (with “NIDEK”) ASCII characters are used for data transmission and reception. 1 RS command Sends a request for 2 SD command to the external computer from the ARK-530A/510A. H: HEX (Hexadecimal) 2 SD command Sends a request for measurement data transmission to the ARK-530A/510A from the exter- nal computer.

  • Page 12: Data Format

    Data Data When the ARK-530A/510A receives the SD command, data transmission is started in this format. When the “71. I/F MODE (Interface Mode)” parameter is set to “NCP10”, four digits of checksum are added after “EOT” in each data format.

  • Page 20: Cr (Carriage Return) Code

    When a personal computer is used as the external computer for receiving the data, it may be neces- sary to add “CR” code to the end of data to be transmitted in one line. The ARK-530A/510A allows you to select whether or not to add “CR” code to the end of data.

    CR CODE See “2.12 Parameter Settings” in the operator’s manual for the method of setting parame- ters. Measure eyes with the ARK-530A/510A and press the print button when the sample program is running. When data is transmitted successfully, measurement data is displayed on the monitor of the computer.
