1. OUTLINE OF COMMUNICATION
1.1 Outline of Communication Function
The LM-1000, LM-1000P, or LM-1200 comes standard with a USB interface that enables transmission
of measured data to an external computer. This manual explains the method of receiving the mea-
sured data from the LM-1000, LM-1000P, or LM-1200 through the USB 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.
1.1.1 Basic interface specifications
1.1.2 Setting the parameter related to communication
Among the parameters related to communication, set the two parameters below: The other parame-
ters related to communication have no influence on the data exported through the USB interface.
* The underlined option shows the factory setting.
For the method of setting parameters, see “2.13 Setting Parameters” of the LM-1000, LM-1000P, LM-
1200 Operator's Manual.
• 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 Communication specifications In accordance with the USB V1.1 specifications
(B-type connector on the LM side)
2 Data format ASCII
3 Error detection Checksum
4 Interface cable Standard USB cable (Shield type)
5 Activation of transmission Operation of the print button
1CR Code OFF, ON
2PrismTx OFF, ON, Display

OUTLINE OF COMMUNICATION: Outline of Communication Function
1 : CR Code
This is for selecting whether to attach CR (carriage return) code at the end of data to be transmitted.
Set this parameter to “ON” when the communication software on the computer needs the CR code to
terminate the reception of the data character string.
2 : Prism Tx
This parameter is for selecting whether to transmit the measured prism value.
1.1.3 Installation of the USB driver
The computer needs the USB driver to receive the data measured by the LM-1000, LM-1000P, or LM-
1200.
Install the provided USB driver attached to the USB cable (option) to the computer.
For the USB driver installation procedure, refer to “3. INSTALLATION OF USB DRIVER”
(page 37).
Purchase a program used for data reception by yourself.
OFF The CR code is not added.
ON The CR code is added to the output character string.
OFF The measured prism value is not transmitted at any time.
ON The measured prism value that is displayed in rectangular coordinates is
transmitted at all times.
Display When the measured prism value is displayed on the screen, it will be
transmitted. If not, it will not be transmitted.

2. DATA FORMAT
Data measured by the LM-1000, LM-1000P, or LM-1200 and represented in ASCII character codes
are transmitted in the specified format and the specified sequence. Data that has not been obtained is
not transmitted; the length of data changes with the measurement conditions: Write the program using
character strings to be added for a search for desired data as below:
Data is transmitted only from the LM to the computer; the computer is not provided with a function etc.
for requesting a command. Data transmission is triggered by the operation of the print button. The
data that has been saved in the memory when the print button is pressed is transmitted. During the
measurement, measured data that is in the memory when the print button is pressed is saved and
transmitted.
2.1 Format of Entire Data
The format of the entire data to be transmitted is explained:
(1) SOH (01H)
This is referred to as “communication control character” and frequently used for data trans-
mission etc. A single SOH character is represented as “01H” in hexadecimal character
codes.
SOH represents “the start of a character string".
Data (3), (6), (7), (8), and (10) is a similar control character.
(2) “DLM”
Data that is comprised of three characters represent “Data of LM”.
(3) STX (02H)
This communication control character represents “the start of data”.
SOH "DLM" STX NIDEK ID Measured data ETB CR EOT CS1 - CS4 CR

(4)NEDEK ID

LM-1200
* In the lower line, the ASCII code of each character is represented by hexadecimals.
The first two characters, “ID”, that is referred to as an identification code of the character
string represents the type of the data that follows. The identification code that is also added
to the head of the measured data is used for searching for desired data. The latter ETB, a
communication control character, represents “a delimiter of data”. Some software on the
computer needs the CR code at the end that represents “the end of the character string”. As
necessary, set the CR Code parameter.
(5) Measured data, (6) ETB, (7) CR
See “2.2. Format of each data (Page 8)”.
(8)EOT(04H)
This is a communication control character that represents “the end of the character string”.
In the case of measured data, this character represents the end of data.
(9)CS1 - CS4, (10) CR
This is a checksum for error detection. The value of the checksum is the simple sum of
“SOH” at the head to “EOT” in the data format except the CR code. The hexadecimal num-
bers in the low-order two bytes are represented by four-byte ASCII codes as a simple sum of
SOH at the head of the data to “EOT (04H)”. The checksum is calculated from the data
received by the computer in the same way. Normal data reception is identified by an agree-
ment between both sums.

The LM transmits the following types of data. These types of data are output according to the lens
measurement mode, whether the data has been measured or not, and the condition for the lenses
(single, left or right).
{: Output if measured ×: Not output
*1: LM-1200 only.
When the parameter is not set to “ON”, measurement or data output is not performed.
*2: 1st addition power only
*3: In the case of “Single (not the right- nor left-eye lens)” state, only single data is output.
When both left- and right-eye lenses are measured, the data is output in following order:
“Right” “Left”.
*4: In the prism layout, the measured value is output for the PRISM value.
