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/510Acomes 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.

This chapter describes the specifications for the interface for data transmission between the ARK-530A/510A and a personal computer, etc.

Basic interface specifications

As the Transmission system, Parity check, and Stop bit length are fixed as above, it is necessary forthe external computer to conform to these specifications.

2.1.1 Communication sequenceTwo types of the transmission sequences, “NIDEK” and “NCP10”, can be selected by setting the “71.I/F MODE” parameter.

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 complicatedcontrols such as the DTR control, DSR control, RS command control, SD command control, etc., itallows easier communication compared with “NIDEK”. However, with “NCP10”, data transmission inresponse to a request from the personal computer is not available. Select a transmission sequencethat suits your needs or purposes.

When the I/F MODE parameter 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.

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 lowstate on a line. The DTR signal of the external computer does not affect the transmission under eithercondition.In addition, since the RS/SD command control is not performed, pressing the print button ( )sends the data directly.

1 RS command

Sends a request for 2 SD command to the external computer from the ARK-530A/510A.

2 SD command

Sends a request for measurement data transmission to the ARK-530A/510A from the exter-nal computer.

1) For requesting AR measurement data:

2) For requesting KM measurement data:

3) For requesting AR and KM measurement data:

3 CL command

Sends a request to clear measurement data to the ARK-530A/510A from the external com-puter.

This process clears the above commands. This is the equivalent of pressing the print button( ), after which preparations for the next measurement are made.

3. LAN COMMUNICATION

3.1 Outline of LAN Communication

3.1.1 Outline of communication functionThe ARK-530A/510A creates XML (measurement results and information) and JPEG (measurementring 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 inexternal computers using CIFS (Common Internet File System). Chapter 3 explains the method ofreceiving measurement data from the ARK-530A/510A using this LAN interface.

Basic communication specifications

Network settings such as the IP address and file share of external computers need to be specified accord-ing 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.

1 Basic specifications CIFS

2 Connector RJ-45

3 Standard 10/100Base-TX

4 Cable Straight

5 Compatible OS Windows 2000, XP, Vista

CAUTION• Be sure to connect to the PC via a network hub.Do not connect to the PC directly. Connection failure may occur.

LAN COMMUNICATION: Outline of LAN Communication

3.1.2 Reception structure of measurement dataMeasurement data transmitted from the ARK-530A/510A is captured by the receiver PC as shown inthe illustration below.

Measurement data transmitted via LAN are written in the shared folder set in the receiver PC. Mea-surement data is written in XML format in the shared folder. When there is image data, JPEG formatfiles are written in the shared folder. Then, measurement data is extracted by filing software and savedin the database.

3.2 Data Format

3.2.1 Folder configurationTransmitted 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 folderbelow including device error code.

When captured properly, transmitted measurement data is erased by the receiver software.Therefore, it cannot be checked.

3.2.2 Measurement data (image data) output fileThere are two types of output files normally produced: measurement data and image data (AR ringimage).

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.

File name

File names of measurement data (image data) transmitted from the device to the receiver PC are as fol-lows:ID characters that cannot be used for file names are all converted to tilde (∼).

Measurement data (XML file)

Image data (JPEG file)

3.2.3 Response to data acquisitionThere are two device modes. One is to write data to the shared folder and the other is to confirm datareception.Data acquisition is checked by the device monitoring that the XML file of measurement data is nolonger present. On the receiving end, after a data file is produced, the existing data is read out anddeleted or renamed.The device indicates an error if the XML file remains present after 5 seconds of file writing (JPEG filesare not monitored.)

3.2.4 XML file configurationTags for data which have not been measured are not output. For example, when only the right eye ismeasured, there are no left-eye tags. Regardless of the print format and communication format of theparameter, all output-enabled data are output.

3.2.5 Style sheetXML files are supported by a style sheet. They cannot be displayed in Internet Explorer without stylesheet 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 measurementdata is received. An existing RKT_style.xsl file is not overwritten.Please note that when the program is changed using the device, that style sheet does not become thenew style sheet unless the existing RKT_style.xsl file is manually deleted.Creating a unique style sheet in the TXT folder allows data to be displayed in the unique format.
