5 1. OUTLINE OF COMMUNICATION 1.1 Interface Type 1 The ARK-530A/510A comes equipped with the following two types of interface to transfer measurement data to external computers: RS-232C interface LAN interface This interface manual describes the method of receiving measurement data from the ARK-530A/510A using the RS-232C interface in Chapter 2 and the LAN interface in Chapter 3. 3

6 OUTLINE OF COMMUNICATION: Interface Type 4

7 2. RS-232C COMMUNICATION 2.1 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 measurement data from the ARK-530A/510A through this interface. 2 This chapter describes the specifications for the interface for data transmission between the ARK- 530A/510A and a personal computer, etc. Basic interface specifications 1 Basic spec In accordance with RS-232C standards 2 Connector DIN 8-pin 3 Transmission method Asynchronous 4 Transmission system Half duplex 5 Baud rate 9600/4800/2400/1200 bit/sec 6 Bit length 8/7 bit 7 Parity check Odd parity 8 Stop bit 1 bit 9 Data code ASCII code 10 CR code YES (added)/ NO (Not added) As the Transmission system, Parity check, and Stop bit length are fixed as above, it is necessary for the external computer to conform to these specifications. 5

8 RS-232C COMMUNICATION: Outline of RS-232C Communication Cable connection External computer Serial communication port (RS-232C) ARK-530A/510A Interface connector 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. Connection to the external computer by any means other than that specified above (Dsub 9P) needs a conversion adapter. 6

9 RS-232C COMMUNICATION: Outline of RS-232C Communication Communication sequence Two types of the transmission sequences, NIDEK and NCP10, can be selected by setting the 71. I/F MODE parameter. COMMUNICATION SEQUENCE NIDEK NCP10 DTR/DSR control Performed Not performed RS/SD command control Performed Not performed Data transmission in response to a request from the PC Possible Not possible 2 Checksum data Not present Present With NIDEK, the transmission sequence is the same as the conventional transmission sequence. With NCP10, press the button to transmit data. Because NCP10 does not need complicated controls such as the DTR control, DSR control, RS command control, SD command control, etc., it allows easier communication compared with NIDEK. However, with NCP10, data transmission in response to a request from the personal computer is not available. Select a transmission sequence that suits your needs or purposes. When the I/F MODE parameter is set to NIDEK DTR/DSR control: Data Sending end Same timing Data Same timing Receiving end T1, T2 = 0.1 sec. (Time-out period: T1, T2 > 0.1 sec.) Disable DTR as soon as possible after the transmission and reception of EOT. 7

10 RS-232C COMMUNICATION: Outline of RS-232C Communication RS/SD command control: [When the print button ( ) is pressed:] [When a data send request is sent from the external computer:] 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. In addition, since the RS/SD command control is not performed, pressing the print button ( ) sends the data directly. 8

11 RS-232C COMMUNICATION: Data Format 2.2 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. 2 SOH C * * STX R S ETB EOT 01H 43H 2AH 2AH 12H 52H 53H 17H 04H H: HEX (Hexadecimal) 2 SD command Sends a request for measurement data transmission to the ARK-530A/510A from the external computer. 1) For requesting AR measurement data: SOH C R M STX S D ETB EOT 2) For requesting KM measurement data: SOH C K M STX S D ETB EOT 3) For requesting AR and KM measurement data: SOH C R K STX S D ETB EOT 3 CL command Sends a request to clear measurement data to the ARK-530A/510A from the external computer. SOH C R M STX S D ETB EOT SOH C K M STX S D ETB EOT SOH C R K STX S D ETB EOT This process clears the above commands. This is the equivalent of pressing the print button ( ), after which preparations for the next measurement are made. When the measurement is started after preparation, the previous data is cleared and the next patient is measured. 9

SOH ETB EOT 3 2 C F The checksum is represented by four hexadecimal digits. The value of the checksum is the simple sum of SOH to EOT in the data format. However, the CR code is not included into the calculation of the checksum when the CR code is added. CAUTION Data Checksum (4) Set the 74. BIT LENGTH parameter to 8. When the parameter is set to 7, the codes that correspond to kana-characters are not exported successfully. 17

20 RS-232C COMMUNICATION: Data Format CR (Carriage Return) Code When a personal computer is used as the external computer for receiving the data, it may be necessary 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. See Step 3 of Interface between the ARK-530A/510A and external PC (page 19) The data to be transmitted when CR code is added: 1 RS command with CR code added SOH C * * STX R S ETB EOT CR 0DH CR code is added to the end of a command statement. 2 Data with CR code (When the 71. I/F MODE parameter is set to NIDEK ) SOH D R M STX Data ETB CR Data ETB CR Data ETB CR EOT CR CR code is added to the end of the ETB code and the end of data. 3 Data with CR code (When the 71. I/F MODE parameter is set to NCP10 ) SOH D R M STX Data ETB CR Data ETB CR Data ETB CR EOT C1 C2 C3 C4 CR Checksum CR code is added to the end of the ETB code and the end of data. 18

21 RS-232C COMMUNICATION: Communication Program 2.3 Communication Program Interface between the ARK-530A/510A and external PC Actual transmission method is explained using the attached sample program in this section. As the external computer, an IBM PC compatible (IBM100% COMPATIBLE) is used. 1 Connect between the port of the ARK-530A/510A interface connector and serial communication port (RS-232C) of the external computer with an interface cable (OPIF-15). 2 2 Enter a sample program of one of transmission sequences to the external computer. Visual Basic is used as a BASIC application. 3 Set the ARK-530A/510A as specified: I/F MODE Depending of the sample program BAUD-RATE 9600 BIT LENGTH 8 CR CODE YES See 2.12 Parameter Settings in the operator s manual for the method of setting parameters. 4 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.

29 3. LAN COMMUNICATION 3.1 Outline of LAN Communication Outline of communication function The ARK-530A/510A creates XML (measurement results and information) and JPEG (measurement ring image) files of the measurement data to be used in electronic filing systems for ophthalmology, and it comes equipped with the LAN interface that outputs those created files to shared folders in external computers using CIFS (Common Internet File System). Chapter 3 explains the method of receiving measurement data from the ARK-530A/510A using this LAN interface. 3 Basic communication specifications 1 Basic specifications CIFS 2 Connector RJ-45 3 Standard 10/100Base-TX 4 Cable Straight 5 Compatible OS Windows 2000, XP, Vista Network settings such as the IP address and file share of external computers need to be specified according to the network setting manual of the AR-310A, AR-330A, AR-360A, ARK-510A, ARK-530A, ARK-560A. Cable connection Connect the LAN cable to the LAN connector on the underside of the device. Connect the other end of the LAN cable to the hub to which the receiver PC is connected. Be sure to connect to the PC via a network hub. CAUTION Do not connect to the PC directly. Connection failure may occur. Network hub LAN cable ARK-530A/510A Receiver PC 27

30 LAN COMMUNICATION: Outline of LAN Communication Reception structure of measurement data Measurement data transmitted from the ARK-530A/510A is captured by the receiver PC as shown in the illustration below. Receiver PC Transmission of measured data from the device via LAN Filing software Database Shared folder XML JPG Measured data Extraction and storage of measured data Measurement data transmitted via LAN are written in the shared folder set in the receiver PC. Measurement data is written in XML format in the shared folder. When there is image data, JPEG format files are written in the shared folder. Then, measurement data is extracted by filing software and saved in the database. 28

31 LAN COMMUNICATION: Data Format 3.2 Data Format Folder configuration Transmitted data is saved in the shared folder and lower levels in the folder structure shown below. If data has not been captured in the receiver software, check whether data is written in any folder below including device error code. When captured properly, transmitted measurement data is erased by the receiver software. Therefore, it cannot be checked. Shared folder RKT TXT Measurement data (XML file) 3 JPG Image data (JPEG file) Measurement data (image data) output file There are two types of output files normally produced: measurement data and image data (AR ring image). Measurement data Image data (AR ring image) One file for one patient All sets of data such as right and left eyes, AR, and KM are output to one XML file. One file for each eye, 2 files bit gray scale JPEG compression 75 When no style sheet file (RKT_style.xsl) is found in the TXT folder, a style sheet file is also output. When a style sheet file exists, a new file is not ouput. 29

32 LAN COMMUNICATION: Data Format File name File names of measurement data (image data) transmitted from the device to the receiver PC are as follows: ID characters that cannot be used for file names are all converted to tilde ( ). Measurement data (XML file) Delimiter (underbar) ARK ABCDEFGHIJKLMN xml Header 3 characters fixed ARK ID14 characters fixed (If no characters, space is entered.) Date and time 14 characters fixed (YYYYMMDDHHMMSS) XML extension (3 characters fixed) Image data (JPEG file) Delimiter (underbar) Type (A = AR ring image) Right of left eye (R/L) Unit (1 fixed) ARK ABCDEFGHIJKLMN RA1. jpg Header 3 characters fixed ARK ID14 characters fixed (If no characters, space is entered.) Date and time 14 characters fixed (YYYYMMDDHHMMSS) JPEG extension (3 characters fixed) Response to data acquisition There are two device modes. One is to write data to the shared folder and the other is to confirm data reception. Data acquisition is checked by the device monitoring that the XML file of measurement data is no longer present. On the receiving end, after a data file is produced, the existing data is read out and deleted or renamed. The device indicates an error if the XML file remains present after 5 seconds of file writing (JPEG files are not monitored.) 30

33 LAN COMMUNICATION: Data Format XML file configuration Tags for data which have not been measured are not output. For example, when only the right eye is measured, there are no left-eye tags. Regardless of the print format and communication format of the parameter, all output-enabled data are output. Common data (No tags) Version, date and time, or such Patient data Measurement conditions Right eye data AR data Measurement data (1 to 10) Median value Trial lens data Contact lens data KM data Measurement data (1 to 10) Median value Sagittal measurement data KM periphery Measurement data (1 to 10) Median value CS (Corneal Size) data PS (Pupil Size) data Left eye data Same as right eye PD (Pupillary Distance) data Style sheet XML files are supported by a style sheet. They cannot be displayed in Internet Explorer without style sheet files (RKT_style.xsl) in the TXT folder. (Use a text editor to check the contents.) When there is no RKT_style.xsl file in the TXT folder, it is automatically produced when measurement data is received. An existing RKT_style.xsl file is not overwritten.
