5 1. OUTLINE OF COMMUNICATION 1.1 Outline of Communication Function 1 The LM-1000, LM-1000P, or LM-1200 comes standard with an RS-232C interface that enables transmission of measured data to an external computer. This manual explains the method of receiving the measured data from the LM-1000, LM-1000P, or LM-1200 through the RS-232C interface. The following sections describe the specifications for the interface for communication between the LM-1000, LM-1000P, or LM-1200 and an external device such as a personal computer Basic interface specifications Be sure to set the A.Prt S and A.Prt R/L parameters to OFF before communication. Failure to do so could cause a printer error. 1 Basic specifications In accordance with the RS-232C specifications 2 Communication method Asynchronous 3 Transmission type Half duplex 4 Communication mode (ComMode) NIDEK, PC, NCP10 5 Baud rate (BaudRate) 1200, 2400, 4800, 9600 (bps) 6 Parity (Parity check) OFF, ODD, EVEN 7 Data bits 7bit, 8bit 8 Stop bits 1bit, 2bit 9 CR code OFF, ON 10 Data code ASCII code The underlined options show the factory settings for communication with NIDEK devices. The settings of Parameter 4 ComMode to Parameter 9 CR Code are changeable. For the procedure for changing the parameter settings, see 2.13 Setting Parameters of the LM- 1000, LM-1000P, or LM-1200 Operator s Manual. The settings of Parameter 5 BaudRate to Parameter 8 StopBits are changeable only when Parameter 4 ComMode is set to PC or NCP10. If Parameter 4 ComMode is set to NIDEK, Parameter 5 BaudRate to Parameter 8 StopBits are automatically set for connection with NIDEK devices; once the parameters are set automatically, the settings are unchangeable. 1

6 OUTLINE OF COMMUNICATION: Outline of Communication Function Addition of CR code Set the CR Code parameter to ON when the communication software on the computer side needs the CR code to terminate the reception of the character strings. (BASIC language etc.) The CR code is added to the data sent from the LM; For character strings sent from the computer, whether the CR code is added or not does not matter. To enable communication with a computer, it is necessary to keep consistency in the settings of communication parameters between the LM and computer. Before data communication, also confirm the settings of the communication parameters on the computer side. Setting related to the transmission of prism data Set the Prism Tx parameter to suit the needs for prism data. 11 Prism Tx OFF, ON, Display OFF ON Display The measured prism data is not transmitted at any time. Choose this option not to transmit prism data or restrain the size of data to be transmitted. The measured prism data is transmitted at all times. Choose this option to make the external device control and align measured lenses. The measured prism data is transmitted in a coordinate system in which the data is represented on the screen, OFF: The measured prism data is not transmitted. BU/D BI/O: The measured prism data in a rectangular coordinates is transmitted. P-B: The measured prism data in a polar coodinates is transmitted. Set the representation form of prism data by setting the Prism parameter. 2

Be sure to connect a wire between RTS (7) and CTS (8) on the computer side. It is unnecessary connect a wire between RTS (4) and CTS (5) on the LM side. Use the DIN 8-pin connector (DIN Standard No.45329) on the LM side. In the above example, the D-Sub 9-pin connector is connected to the computer side. If the used connector is different from the D-Sub 9-pin connector, connect respective signal wires as shown by referring to the instruction manual provided with the computer. Use a special interface cable that is available as an option (OPIF-11, 5 m) between the DIN 8-pin and D-Sub 9 pin connectors if necessary. 3

9 2. DATA FORMAT Among transmitted data are commands such as Request to Send other than measured data. In a sequence of transmission of measured data from the LM to the computer etc., the computer transmits Send Data command to the LM, and the LM receives the command and sends measured data. The software on the computer reads the received data strings according to the format information and then performs necessary processing (display of data on the screen, storage of data on disks, etc.) 2 * When the ComMode parameter is set to NCP10, the transmission and reception of commands are not performed. This chapter explains the formats of these commands or measured data. Symbols other than ordinary characters in commands or data strings are described as communication control characters that are commonly used in data transmission. These signals are added at the start or end of character strings or to delimit data. Character name Decimal Hexadecimal Description SOH 1 01H Start of heading character STX 2 02H Start of text character ETB 23 17H End of transmission block EOT 4 04H End of character string CR 13 0DH Means the end of the input character string for some software on the computer. The CR code is added to the data output from the LM when the CR Code parameter is set to ON. The CR code is not added to the character strings transmitted from the computer. In addition, whether the line feed (LF: 0AH) code is added or not after the CR code does not matter. 5

10 DATA FORMAT: Command Format 2.1 Command Format The commands (control character string) that are transmittable from and receivable by the LM are described below. These commands reciprocally control the LM and computer to make them transmit and receive data. The format of a basic command is described immediately below: SOH C L M STX R D ETB EOT CR : Character string (10 characters in this case) 01H 43H 4CH 4DH 02H 52H 44H 17H 04H 0DH : Character code (H = Hexadecimal) The CR code is added. Characters representing the RD command Command to be sent to the LM. ** represents the unspecified commands. Characters representing a command (1) RD command (Computer LM) Command for the computer to request the LM to save the measured data. The command corresponds to the actuation of the read key of the LM. The command also holds the values displayed on the screen. Before making the LM to transmit data to the computer, this command should make the LM to save the measured data. SOH C L M STX R D ETB EOT CR 01H 43H 4CH 4DH 02H 52H 44H 17H 04H 0DH (2) SD command (Computer LM) Command for the computer to request the LM to transmit measured data. The computer sends this command to the LM when the computer is ready for the reception of measured data. SOH C L M STX S D ETB EOT CR 01H 43H 4CH 4DH 02H 53H 44H 17H 04H 0DH 6

11 DATA FORMAT: Command Format (3) RS command (LM Computer) Command for the LM to request the computer to receive measured data and to send the SD command. The command is used to transmit data with switch operation of the LM. The computer sends the SD command to the LM when the computer receives the RS command and is ready for the reception of measured data. SOH C * * STX R S ETB EOT CR 01H 43H 2AH 2AH 02H 52H 53H 17H 04H 0DH C** represents that the LM sends the command to an infinite number of destinations. 2 (4) CL command (Computer LM) of the LM. This com- Command for the computer to make the LM clear the data in it. The command corresponds to the actuation of the clear button mand also releases the fixed data indication. SOH C L M STX C L ETB EOT CR 01H 43H 4CH 4DH 02H 43H 4CH 17H 04H 0DH (5) AB command (Computer LM) Command for the computer to set the abbe number for the LM in accordance with the material of the measured lens. This command should be sent before measurements. When the LM receives the AB command from the computer, the LM displays X: 40 on the top of the screen for example. ( X: represents reception.) If the abbe number is not specified, the LM measures lenses with the abbe number that is set internally. The abbe number specified by the AB command is in effect until it is reset on the LM. SOH C L M STX A B n n ETB EOT CR 01H 43H 4CH 4DH 02H 41H 42H 17H 04H 0DH nn = Abbe number (20 to 60) e.g.) 34H, 31H for number 41 7

45 3. COMMUNICATION PROCEDURE 3.1 Outline The procedure for transmitting data measured by the LM to the computer etc. is explained. 1 Save measured data on the LM. Press the read key of the LM or send RD command from the computer. 2 Transmit the saved data to the computer. Press the print button of the LM-1000P/LM-1200 (or export button of the LM- 1000) or send SD command from the computer. 3 3 As the computer receives measured data, it displays the data on the screen or saves it to a floppy disk. Therefore, the computer needs a program that sends or receives these commands or these items of data, analyzes and processes (displays, saves etc.) the received data. In this manner, the operator can choose the following options for data transmission and reception: To perform automatic data transmission with the operation buttons on the LM side, to use the computer to give all the commands to the LM from the data storage to data transmission, and to use the operation buttons on the LM side and the computer in combination. 41

46 COMMUNICATION PROCEDURE: Communication Control Signals (DTR Output to DSR Input) 3.2 Communication Control Signals (DTR Output to DSR Input) The communication control method when the ComMode parameter is set to NIDEK is described. To transmit and received Command and/or Data, it is necessary to connect the DSR (Data Set Ready) and DTR (Data Terminal Ready) wires as well as the TXD (Transmit exchange Data) and RXD (Received exchange Data) wires. (Also see Cable connection (Page 3).) The DTR-to-DSR wire lets both devices know if the other device is ready for communication. If one device is ready for communication, it sends DTR = ON to the other device. If one device is not ready for communication during printout by the LM or the processing of the previous data by the computer, it sends DTR = OFF to the other device to let the other device know the status of one device. The status of the other device is judged by ON or OFF of DSR. In this way, unwanted communication troubles can be prevented. The figure below shows the changes in the DTR signals when the computer sends SD command and the LM sends Data back in response to the command. TXD DTR ON OFF Computer side 1) 2) 3) 4) 6) Command 7) 10) 11) LM side DTR ON OFF TXD 5) 8) 9) Data T1 T2 T1, T2 0.1 sec (Time out when T1, T2 > 0.1 sec.) 1) Both the computer and LM are out of communication. The DTR signal of both devices is OFF. 2) The computer enables DTR (ON) to send Command to the LM. 42
