7 2. RS-232C COMMUNICATION 2.1 Outline of RS-232C Communication Outline of Communication Function In order to transmit the data measured by the TONOREF II to an external computer, the TONOREF II comes standard with an RS-232C interface. This manual provides the method of receiving the measured data from the TONOREF II through this interface. 2 In this Interface Manual, Section 2 describes the method of receiving measurement data from the TONOREF II using the RS-232C interface. 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) Because 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. 3

8 RS-232C COMMUNICATION: Outline of RS-232C Communication Cable connection External computer Serial communication port (RS-232C) TONOREF II Interface connector D-sub 9P (female) DIN 8P Connect between the port of the TONOREF II interface connector and the serial communication port (RS-232C) of the external computer with the above interface cable (Model: OPIF-11). This interface cable allows the I/F MODE parameter to be set either to Nidek or NCP10. Any connector of the external computer other than the one specified above (Dsub 9P) needs a conversion adapter. 4

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 I/F MODE parameter. COMMUNICATION SEQUENCE NIDEK NCP10 DTR/DSR control Yes No RS/SD command control Yes No Data transmission in response to a request from the PC Available Not available 2 Checksum data OFF Available 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. 5

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 TONOREF II 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. 6

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 TONOREF II. 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 measured data transmission to the TONOREF II from the external computer. 1) For requesting AR measured data: SOH C R M STX S D ETB EOT 2) For requesting KM measured data: SOH C K M STX S D ETB EOT 3) For requesting AR and KM measured data: SOH C R K STX S D ETB EOT 4) For requesting NT measured data: SOH C N t STX S D ETB EOT 5) For requesting AR, KM and NT measured data: SOH C R N STX S D ETB EOT 7

12 RS-232C COMMUNICATION: Data Format 3 CL command Sends a request to clear measured data to the TONOREF II from the external computer. All-clear process is executed by any of the commands shown below. After the execution of all-clear process which corresponds to the actuation of the print button ( ), 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. SOH C R M STX C L ETB EOT SOH C K M STX C L ETB EOT SOH C R K STX C L ETB EOT SOH C N T STX C L ETB EOT SOH C R N STX C L ETB EOT 8

When the I/F MODE (Interface Mode) parameter is set to NCP10, four digits of checksum are added after EOT in each data format. Data transmitted from the TONOREF II: 1) Company name / Model name 2) Patient number 3) Date and time of measurement 4) Vertex distance 5) Near working distance 6) Objectively measured data 7) Contact lens conversion data 8) Optimum trial lens data 9) Pupillary distance 10) KM measurements 11) Corneal size measurements 12) Pupil size measurements 13) NT measurements 14) Checksum 9

14 RS-232C COMMUNICATION: Data Format Data The number inside the parentheses indicates the number of characters transmitted. 1 Company name / Model name When the I/F FORMAT parameter is set to SHORT and a request for KM data only is sent (See 2 SD Command of 2.2.1), the company name and model name are not transmitted. 2 Patient number 3 Date and time of measurement Even if the time format is set to AM/PM, the communication Data is set to 24H. 4 Vertex distance 5 Near working distance 10

15 RS-232C COMMUNICATION: Data Format 6 Objectively measured data If median values have been obtained after three or more measurements, the median values are transmitted first and then respective items of data are transmitted (in order of acquisition time with the latest data first). Order of R/L: L R. 1) Left eye data If 45. CAT MARK parameter is set to YES, CAT measured mark * is inserted on the data that was measured by AR in the condition of indicating the CAT measurement mode mark ( ). 2 2) Right eye data 3) Error data Measurement errors are stored in memory and transmitted together with AR measured data. Right eye data Type of error Content +O Positive SPH range over error Left eye data -O Negative SPH range over error CO CYL range over error If the I/F FORMAT parameter is set to SHORT: Only median values are transmitted as objectively measured data. If median values have not been obtained, only the latest data is transmitted. The error data is not transmitted. 11

21 RS-232C COMMUNICATION: Data Format 14 Checksum If the I/F MODE parameter is set to NCP10, a checksum is added to the data format. It is added after EOT of each data format. 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. 2 CAUTION Set the BIT LENGTH parameter to 8. If the parameter is set to 7, the codes that correspond to kana-characters are not exported successfully. 17

22 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 TONOREF II allows you to select whether or not to add CR code to the end of data. See Interface between the TONOREF II 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 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 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

23 RS-232C COMMUNICATION: Communication Program 2.3 Communication Program Interface between the TONOREF II 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 TONOREF II interface connector and serial communication port (RS-232C) of the external computer with an interface cable (OPIF-11). 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 TONOREF II as specified: I/F MODE Depending of the sample program BAUD-RATE 9600 BIT LENGTH 8 CR CODE YES See 2.8 Parameter Settings in the operator s manual for the method of setting parameters. 4 Measure eyes with the TONOREF II and press the print button on condition that the sample program is running.
