1-3.Features
This data recorder assures the synchronization of video
and analog signals and allows their recording.
This standalone data recorder has been designed to be
compact and lightweight in consideration of field use.
(An optional battery unit designed for this recorder is
also available.)
oOne-channel recording is possible when the video
input is HD resolution at 30 fps, and two-channel
high-quality recording is possible when it is VGA reso-
lution at 30 fps.
oVideo signals are input using a gigabit Ethernet
interface.
Cameras can be easily connected to the main unit
using dedicated camera cables for control signals and
power supply.
We have published a list of cameras that have been
connected and tested for operation on our website
(http://datarecorder.jp/en/).
oRecording is supported for up to four channels of
24-bit analog input in the DC 0 Hz − 40 kHz frequency
range.
A wide dynamic range is realized using 24-bit analog
to digital conversion.
oAnalog input using DC, AC and ICP sensors is supported.
oFor convenience at measurement sites, CAN, GPS and
pulse signal input are supported as standard.
oCFast cards enable high-capacity data recording
at high transfer rates. Recorded data is easy to use
and multiple cards can be prepared, allowing easy
creation of separate files according to recording pur-
poses, for example.
SD cards can be used for recording when input-
ting only analog signals, making possible the use of
recording media that is easy to obtain.
oFor operation, the unit includes a 5.7-inch color TFT
display with excellent visibility. The graphical inter-
face design enables intuitive operation using the
touchscreen. This also makes it easy to check video
and analog signal recording at measurement sites.
A panel lock function is also included, however, to
prevent misoperation.
oNumerous and convenient additional functions include
trigger recording starting/stopping.
1. Introduction
oSynchronized connection of two units is supported,
allowing the number of recording channels to be
increased.
In addition, synchronized connection with our more
advanced products (WX/LX series) is supported,
allowing the number of recording channels for ana-
log signals to be increased greatly.
oA wide DC power input range (DC 11 V – 17 V) is
supported.
oThe AC adapter, which is an included accessory, sup-
ports universal power supplies. (AC 100 V – 240 V)

1-4-3.Media that has been verified to
operate with this system
This unit uses CFast and SDHC cards for recording and
playback.
We provide a list of CFast and SDHC cards that we have
verified for operation with this unit on our Industrial
Products Division data recorders website.
http://datarecorder.jp/en/
You can also contact us. (For contact information, see
the last page.)
oPrepare media for use only with the VR-24.
oTo ensure stable recording, you should try to
keep the the total number of files to 1000 or less.
Moreover, before recording, confirm that the record-
ing medium has enough open space.
1. Introduction
1-5.TAFFmat format
1-5-1.Type of files
The VR-24 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 a “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
Video file*: Contains camera video data
AVI format with “avi” extension
*Files are created when recorded.
oTwo video files are created if two cameras are used.
1-5-2.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 to the
media, the next ID number is used.
Set the “File name” type on the RecFile page of the FILE
settings. For the file name, use up to 8 half-width alpha-
numeric characters. A 4-digit ID number (starting from
0001) is attached to these file names for a maximum of
12 characters.
At the ends of the names of video files, “C1” is added for
camera 1 and “C2” is added for camera 2.
oIf the ID number exceeds 1000, recording will stop.

1-5-3.Media directory structures
The directory structure of each medium is as follows.
Root directory
VR-24_DATA *1
Aaaaaaaa0001.dat *2
Aaaaaaaa0001.hdr *2
Aaaaaaaa0001.wav *2 *3
Aaaaaaaa0001_C1.avi *2 *3
Aaaaaaaa0001_C2.avi *2 *3
1 VR-24_DATA
This directory is made automatically when
the medium is formatted. When the medium
is inserted in an VR-24, this directory is made
automatically if it does not already exist.
2 These files are created for each ID.
3 These are created when recorded.
1-5-4.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 val-
ues 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 docu-
ment, 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 6 kHz sampling
frequency

1-5-5.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 inte-
ger 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 9 for
information about SLOPE and Y_OFFSET.

1-5-6.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.
