2.1 Outline of RS-232C Communication

The OPD-Scan III comes standard-equipped with a RS-232C interface to transmit measurement datato an external computer. This chapter explains the method of receiving the measurement data fromthe OPD-Scan III by using this interface.

This section describes the specifications of the interface for communication between theOPD-Scan III and an external device such as a personal computer.

2.1.1 Basic interface specifications

* The underlined settings are the standard settings.

As the transmission system is fixed as above, it is necessary for the external computer to conform tothis specification.

Communication protocol

The setting of the communication device at the other end (Connected Device) toggles the use of com-munication protocol between "NIDEK" and "Use NCP10 Protocol".

2 Baud rate 110/300/600/1200/2400/4800/9600/19200/38400/57600/115200 bit/sec

3 Bit length 7/8 bit

4 Parity check Odd/Even/None

5 Start bit 1/1.5/2 bit

6 Stop bit 1/1.5/2 bit

7 CR code YES (added)/ NO (Not added)

8 Send all data Checked/Not-checked

Communicationprotocol

Connected device Data link control

NIDEK Previous RT Series, RT-5100Support, Eye Care Card

With the RS-232C control cable (DTR/DSR), a notification requestinga permission for data transmission is sent to the connected device.

Use NCP10Protocol

Computer Data transmission begins at a desired point without aconfirmation from the receiver (non-procedural).

• The "Connected Device" is selected from "Options" in the Settings screen (Communicationtab). The communication protocol is automatically set by the selection of the "ConnectedDevice".

RS-232C COMMUNICATION Outline of RS-232C Communication

2.1.2 RS-232C communication External computer (such as personal computer)

The computer must be provided with an RS-232C interface, capable to check, and controlthe signal level of HIGH/LOW with the DSR signal line.

RS-232C cable

Software (program)

The program used to receive measurement data from the OPD-Scan III must be created sothat the data conforms to the external computer.

This RS-232C cable can be used for both “NIDEK” and “Use NCP10 Protocol” communica-tion protocols.

In addition, prepare an actual program to receive the measurement data.

2.1.3 Communication sequence Two types of transmission sequences, “NIDEK” or “Use NCP10 Protocol” can be selected by the set-ting of “Conection Device” parameter.

With "Use NCP10 Protocol" selected, the data is transmitted by pressing the finish button. SinceNCP10 does not need complicated controls such as the DTR control, DSR control, RS command con-trol, SD command control, and others, it allows easier communication compared with “NIDEK”. How-ever, with NCP10, data transmission in response to a request from the personal computer is notpossible. Select a transmission sequence that suits your needs or purposes.

When the communication sequence is set to "NIDEK".

DTR/DSR control:

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.

The checksum is represented by four hexadecimal digits. The value of the checksum is thesimple sum of “SOH” to “EOT” in the data format. However, the “CR” code is not included inthe calculation of the checksum when the “CR” code is added.

2.3.5 CR (Carriage Return) codeWhen a personal computer is used as the external computer for receiving the data, it may be neces-sary to add the “CR” code to the end of data to be transmitted in one line. The OPD-Scan III allowsyou to select whether or not to add “CR” code to the end of data.

When the “CR” code is added, the data to be transmitted is as follows:

1 RS command with “CR” code added

“CR” code is added to the end of a command statement.

2 Data with “CR” code added (When the communication protocol is set to “NIDEK”.)

“CR” code is added to the end of the “ETB” code and the end of data.

3 Data with “CR” code added (When the communication protocol is set to “Use NCP10 Proto-col”.)

“CR” code is added to the end of the “ETB” code and the end of data.

RS-232C COMMUNICATION Communication Program

2.4 Communication Program

2.4.1 Interface between the OPD-Scan III and an external computer This section explains the preparation of an external computer and the OPD-Scan III used in an actualcommunication.

1 Preparation of an external computer 1) Set the parameters of RS-232C.

Set the parameters in accordance with “2.1.1 Basic interface specifications” (page 5).

The "Transmission system" and "CR code" are fixed parameters, therefore set the external com-puter to conform these parameters.

As the "Baud Rate", "Bit Length", "Start Bit", "Stop Bit", and "Parity" parameters can be changed onthe OPD-Scan III, set them to the available selections.

* Set the RS-232C parameters of the external computer in accordance with the operator's manualof the external computer.

2) Create a program for receiving the OPD-Scan III measurement data.

2 Connect the OPD-Scan III to the external computer with the RS-232C cable. See “2.1.2 RS-232C communication” (page 6).

3 Preparation of the OPD-Scan IIISet the "Baud Rate", "Bit Length", “Start Bit”, “Stop Bit”, and "Parity" parameters to conformthe settings of the external computer.

Set these parameters in the Settings screen (Communication tab).

See "5.8 Changing Device Parameters" of the OPD-Scan III operator's manual.

* When "Send All Data" is not selected from the Settings screen (Communication tab), themeasurement data is output as follows:

AR measurement value(Objective measurement data)

Only the typical values are transmitted.When typical values cannot be obtained, only the latestmeasurement value is transmitted even if it is a referencevalue.

KM measurement value (duringAR/KM measurement mode)

Only the typical values are transmitted (in mm only).When typical values cannot be obtained, only the latestmeasurement value is transmitted.

KM measurement value (duringOPD/CT measurement mode)

Only the latest value is transmitted (in mm only).

22

2.4.2 Flow of communication programA program used to receive data measured by the OPD-Scan III is necessary to be created on theexternal computer.

When "NIDEK" is selected.

Two methods of receiving measurement data are as follows:

(1) When the OPD-Scan III requests an external computer to receive measurement data.

1) After completion of measurement with the OPD-Scan III, press the Verified & Save buttonin the Verify Examination Quality screen for OPD/CT measurement mode, or Print buttonin the Measurement screen for AR/KM measurement. When these buttons are pressed,the OPD-Scan III sets DTR to high, and waits for a response from the external computer.

(1) The external computer sets DTR to high after confirming that DSR becomes high.

2) When DSR becomes high, the OPD-Scan III outputs the RS command to the externalcomputer, and request the SD command.

(2) The external computer outputs SD command after receiving the RS command.

3) The OPD-Scan III starts outputting the measurement data when the SD command isreceived.

(3) The external computer receives the measurement data. As the data reception completes whencode "EOT" (04H) is received, set DTR to low.

4) The OPD-Scan III starts printing out when the data output is complete.

Even after the printing is complete, the memory for data will not be cleared.

* In Step 1), when there is no response from the external computer (DSR remains low) the OPD-Scan III starts printing out immediately.

(2) When an external computer requests the OPD-Scan III to transmit measurement data.

1) The measurement is performed with the OPD-Scan III.

(1) The external computer sets DTR to high, and notifies the OPD-Scan III that communication hasstarted.

2) The OPD-Scan III sets DTR to high after confirming that DSR becomes high.

(2) Then, the external computer outputs the SD command to the OPD-Scan III.

3) The OPD-Scan III starts outputting the measurement data when the SD command isreceived.

(3) The external computer receives the measurement data. As the data reception completes whencode "EOT" (04H) is received, set DTR to low. To clear the OPD-Scan III measurement data,set DTR to high again, and output the CL command.

4) The OPD-Scan III clears the measurement data when the CL command is received.

4.1 Outline of Map Data Output

Image and numeric data in the summary being displayed can be output. Data can be output in the summary screen (including difference and comparison analyses) or anyscreen for displaying maps. There are three types of data to choose from to be output from the summary screen. Multipletypes can be selected.

For details, see “4.2 Outputting Summary Image Data” (page 52).

Summary image Outputs the contents of a summary as an image (JPEG or BITMAP).

Text data Outputs numeric data being displayed in the map as comma-deliminated texts (CSV).

The text data can be used with various spreadsheet software or for othervarious purposes. The numerical and AR/SimK values, patient information, exam date, or othersbeing displayed in the summary of each map are output.

Examination data Outputs complete measurement data being displayed in a summary. This data is output in a folder with the system ID name that contains multiplefiles.The output data can be imported to the database in other devices. (Data isimported by pressing the Import button in the Utility screen.) The operation is only available when a summary other than the difference orcomparison analysis summary is being displayed.

• Parameters for outputting data can be set in the Settings screen (Data Output tab).There are parameters for data type, output destination, file name, image file format, and others.

When the data is output with “Set Each Time” selected in the Data Output tab, the Export Datascreen is displayed to allow confirmation and changing of the data output parameters. When “SetEach Time” is not selected, data is immediately output in accordance with the setting.

The front office function enables activating the “OPD software for external PC” by specifying ID,patient name, or such through external software and displaying the summary screen (map view) orPatient List screen (exam list) without operation of the “OPD software for external PC”.As a command line option using Windows Command Prompt, the following operations are possible.

Displays the summary screen of the specified patient’s latest examination data

Displays the Exam List screen of the specified patient

Registers a new patient

Edits patient information in a database

5.2 Command Line

In order to identify patient data, “optional parameter” is used in combination with character string (eachpatient data).

Each optional parameter begins with a hyphen ( - ) or slash ( / ) so that it can be identified fromanother, so multiple optional parameters can be specified together.

There must be one space or more (as a separator) between an optional parameter and patient data(character string).

• The screen displayed at startup varies depending on whether the data in the OPD-Scan IIIdatabase conforms to the patient data specified in a command line.
