1. Introduction
1-2. Included accessories
If anything is missing or damaged, contact us. (For con-
tact information, see the last page.)
For a list of included accessories, see “7-3. Included
accessories” on page27.
The AC adapters and AC power cords included with

1-3. Overview
Recording with wide bandwidths, multi channels and
long durations is becoming increasingly important for
measurements in the fields of space exploration, aircraft
development, power generation and railways.
The LX-1000 series fulfills these needs.
These systems use SDHC and SDXC cards as recording
media and can record 16-bit/16-channel data for fre-
quency bandwidths up to DC40kHz.
Up to 64 channels can be provided in 4-channel units.
Furthermore, by synchronizing 4 units, up to 256 chan-
nels can be recorded simultaneously.
The quantization bit depth can be set to either 16-bit or
24-bit, which allows measurements with high dynamic
ranges.
SDXC Logo is a trademark of SD-3C, LLC.
TEAC and TAFFmat are trademarks of TEAC CORPORATION,
registered in the U.S. and other countries.
Other company names, product names and logos are

tive owners.

1. Introduction
1-5. System configurations
This system is comprised of a main unit (LX-1000) and
one or more expansion units (AU-LX1000EPIO).
Main unit (LX-1000)
Expansion unit (AU-LX1000EPIO)
By adding more AU-LX1000EPIO expansion units, you
can increase the number of input and output channels.
We offer products with 1, 2 and 3 AU-LX1000EPIO expan-
sion units.
32-channel model
48-channel model
64-channel model
oWhen multiple AU-LX1000EPIO expansion units are
connected, channel numbering starts with channel 1
at the top left and ends with the last channel (32, 48 or
64) at the bottom right.

1-6-2. Media that has been verified to
operate with this system
This system uses SDHC and SDXC cards for recording and
playback.
We provide a list of SDHC and SDXC cards that we
have verified for operation with this system on our
Information Products Division data recorders website.
https://datarecorder.jp/en/
You can also contact us. (For contact information, see the
last page.)
oIn this manual, SDHC/SDXC cards are referred to as
“SD cards”.
oPrepare media for use only with the LX-1000.
oTo ensure stable recording, try to keep the total quan-
tity of recorded data to 1000 or less. Moreover, before
recording, confirm that the recording medium has
enough open space.
oDo not use a computer to delete, move or otherwise
alter data recorded on an SD card. Doing so could
cause the LX-1000 to become unable to properly
record or play data.
1. Introduction
1-7. TAFFmat format
1-7-1. Type of files
The LX-1000 makes a binary-format data file and ASCII-
format header file each time recording stops or pauses.
Data file: Contains data converted from
analog to digital, etc.
(binary format with“dat” file
extension)
Header file: Contains recording conditions
and other information
Text (ASCII) format with “hdr”
file extension
Voice memo file*: Contains voice memo data
WAV format with “wav” file
extension
GPS file*: Contains GPS data
“gps” file extension
Index file: Contains recording conditions
and other information
Text (ASCII) format with “hdx”
file extension
*Files are created when recorded.
1-7-2. File name
The file name is common to the data file and header file.
An ID number is added to the end of the specified file
name. When you specify a new file name, the ID num-
ber starts from 1. After recording is stopped or paused,
the ID number is automatically incremented each time
the recording restarts. If a data file with the same name
or same ID number already exists when recording, the
next ID number is used.
Set the file name on the LXK Navi File Settings Screen
or the RECORDING FILE Settings Screen of the remote
control unit (optional). For the file name, use up to
29half-width alphanumeric characters. ID numbers
(starting from 001) with the set number of digits are
attached to file names.
When recording to an SD card, the number of digits is
fixed to 3, and the maximum number of characters is 32.
When recording to a computer, the number of digits
can be set from 3 to 5, and the maximum number of
characters is 32–34.
oIf the ID number exceeds the set number of digits,
recording will stop.

1-7-3. Media folder structures
Folder type Name Details
Master folder LXDAT
This is created in the root folder.
Data is managed inside it.
The name is fixed.
Project folders Characters as set
(Example: LX1000-DIR1)
These are created in the master folder.
Their names can be set as desired.
Recording folders Characters as set
(Example: LX1000_)
These are created in project folders.
Their names can be set as desired.
Each time recording starts, a recording folder is created with a
3-digit suffix added automatically.
Recording data Same as recording folder When a recording is divided at 4 GB, a - followed by a three-digit
suffix will be added to the name.

1. Introduction

1-7-4. Data file
16-bit data converted from analog to digital is recorded as 2-byte integer values from -32768 to +32767 while 24-bit
converted data is recorded as 4-byte integer values from -8388608 to +8388607. Negative numbers are shown using
two’s-complement notation.
The byte order is from the lowest to the highest (Intel format).
The data order is from the first sampling channel to the second sampling channel and so on until the last sampling
channel. This order is called the INTERLACED format, and the format name is recorded in STORAGE_MODE in the
header file.
The structure of a data file is as follows. In this document, a collection of data as shown in the example is called a
“scan”. A data file is made of repeated scans.
Example of data for one scan recorded at 6kHz sampling frequency

1-7-4-1. Converting data to physical quantities
16-bit data converted from analog to digital is recorded as integer values from -32768 to +32767 and the value would
be ±25000 when the input is ±100% in the input range settings. 24-bit converted data is recorded as integer values
from -8388608 to +8388607 and the value would be ±6400000 when the input is ±100% in the input range settings.
The input value is obtained from the following formula:
Input value = (A/D conversion value of the data file) × SLOPE + Y_OFFSET
oSee “Explanations of header file”on page8 for information about SLOPE and Y_OFFSET.
1-7-5. Header file
Header files are ASCII-format text files containing information such as recording conditions.
In a header file, each recording-condition entry is written on 1line, with parameters separated by a comma (,). An
example of a header file is shown as follows.
