oo For convenience at measurement sites, CAN, GPS andpulse signal input are supported as standard.
oo CFast 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 purposes, for example.
SD cards can be used for recording when inputting only analog signals, making possible the use ofrecording media that is easy to obtain.
oo For operation, the unit includes a 5.7-inch color TFT
display with excellent visibility. The graphical interface design enables intuitive operation using thetouchscreen. This also makes it easy to check video
and analog signal recording at measurement sites.
A panel lock function is also included, however, toprevent misoperation.
oo Numerous and convenient additional functions include
trigger recording starting/stopping.

1. Introduction

1-5. TAFFmat format
1-5-1. Type of files
The VR-24 makes a binary-format data file and ASCIIformat header file each time recording stops or pauses.
Data file:

Header file:

Voice memo file*:

Video file*:

Contains data converted fromanalog to digital, etc.
(binary format with a “dat” fileextension)
Contains recording conditions
and other information
Text (ASCII) format with “hdr” fileextension
Contains voice memo data
WAV format with “wav” fileextension
Contains camera video data
AVI format with “avi” extension*Files are created when recorded.
oo Two 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 number 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 nameor same ID number already exists when recording to themedia, 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 alphanumeric characters. A 4-digit ID number (starting from0001) is attached to these file names for a maximum of
12 characters.
At the ends of the names of video files, “C1” is added forcamera 1 and “C2” is added for camera 2.
oo If the ID number exceeds 1000, recording will stop.

VR-24_DATA
This directory is made automatically whenthe medium is formatted. When the medium
is inserted in an VR-24, this directory is madeautomatically if it does not already exist.
These files are created for each ID.
These are created when recorded.

1-5-4. Data file16-bit data converted from analog to digital is recorded
as 2-byte integer values from −32768 to +32767 while24-bit converted data is recorded as 4-byte integer values from −8388608 to +8388607. Negative numbers areshown 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 tothe 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 iscalled a “scan”. A data file is made of repeated scans.

1-5-5. Converting data to physicalquantities
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 fromthe following formula:
Input value = (A/D conversion value of the data file) ×
SLOPE + Y_OFFSET
oo See “Explanations of header file” on page 10 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.

3. Connections
3-1. Powering the unit

3-2. Connecting cameras

The VR-24 operates with DC 12V power.
The included AC adapter can be attached to the DC IN
connector on the right side panel to supply power.
To supply power using equipment other than the
included AC adapter, correctly follow the pin number
assignments in “5-1. DC IN power connector” on page
20.
Equipment could be damaged if connections are madewith incorrect pin numbers or voltage that exceeds theguaranteed voltage operating range is supplied.

The circular connector of a dedicated camera cablesends control signals and supplies power for one
camera. When connected to the main unit, the LAN
connector sends video signals.
When connecting cameras to the main unit, always
connect the circular and LAN connectors for one camera in pairs to the same camera number connectors.
Connect camera cables before turning the unit on.

VV ATTENTION
oo The guaranteed DC power supply operating range is
DC 11 V – DC 17 V. Never use a voltage outside thisrange. Doing so could damage equipment or cause
unexpected system shutdowns.
oo Do not supply power to AC adapters or DC INs until
after securely connecting all connection cables
between units.
oo Before disconnecting connection cables, turn off thepower to the AC adapters and DC INs.
oo When using within Japan, use the included AC cordthat has a PSE mark on the plug.
oo When using in the North American region, use theincluded AC cord that has a CSA mark on the plug.

When only connecting one camera, connect it to
CAMERA-1.
Connected cameras will automatically have IP addresses
set when the unit is turned on.
The unit might require some time after putting it into
standby and changing the connection number of thecamera, so we do not recommend doing this when
making measurements.

3-3. TEDS
A Transducer Electronic Data Sheet (TEDS) is a standard
format defined in IEEE 1451.4 for recording information
specific to a measurement sensor that is stored within
the sensor itself. By connecting a TEDS sensor with a
TEDS-compatible VR-24, sensor calibration is madeunnecessary, reducing the time required for measurement preparations.
oo If transducer information is not compliant with the
TEDS IEEE standard, correct information cannot beloaded and displayed.
oo Supports TEDS Ver. 1.0.

Recording starting conditions
Level trigger
Use a level change for the set channel as a trigger.
External trigger
Recording starts when the input through the external
trigger input connector (TRIG IN) becomes the L level(0.6 V or less).
Timeout
If the conditions set to start recording are not met
within a specified time, recording will be forced tostart automatically.
Pre-trigger
By default, the system saves data from the time
between when a recording starting condition occurs
and when a recording stopping condition occurs.

34

7. Recording
When a pre-trigger interval is set, data is recorded
before a recording starting condition occurs, but
only after the system is made record ready.
oo You cannot record voice memos during this time.
Recording stopping conditions
Level trigger
Use a level change for the set channel as a trigger.
External trigger
Recording stops when the input through the external trigger input connector (TRIG IN) becomes the Hlevel (open or 3 V or more).
Recording time
Recording continues only for the set amount of time.
Post-trigger
Even after the above recording stopping conditions
are met, recording will continue for the set amountof time.
oo When recording is stopped manually, however,post-trigger recording will not occur.

7-4-2. Interval recording
Example of one interval recording repetition
Recording time

When the number of repetitions is set to 2 or more,recording will start at the set time and stop after theset recording time has elapsed. Then, the system will
become record ready and start recording again after theset interval. After this process has repeated to record theset number of repetitions, recording will stop.
If the number of repetitions is set to 0, interval recording
will repeat until the recording media is full, or recording
is stopped manually.
Start time
Recording starts at the set time.
ATTENTION
If the set time has already passed when the unit is maderecord ready, recording will not start.
The unit might take some time to become record readyif, for example, there are already many recorded files.
Considering this, set the start time with sufficient sparetime.
Recording time
Recording continues for the set amount of time.
Interval time
If the number of repetitions is set to 2 or morerecordings, this is the amount of time that the system stays in a record ready state from the time one
recording ends until the next recording starts.
Repetitions
Sets the number of repetitions. When set to 0, interval
recording will repeat until the recording media is fullor recording is stopped manually.

Start time
Start recording

Stop recording

With interval recording, when the number of repetitions
is set to 1, recording will start at the set time and stop

If any of these problems should occur, please check the following before requesting service.
ProblemPossible causes and responses

Power will not turn on

Is the AC adapter connected correctly?
Is the DC power supply voltage set within the specified
range?
Is the panel locked? If so, unlock it.
Is compatible media loaded in the VR-24?
Has the media been formatted by the VR-24? If not, use theVR-24 to format it.
Are you using media that has been confirmed to work with
the VR-24?
Always put the unit into standby before inserting or removing media.
Use a CFast card in fixe disk mode.
Do not use a CFast ard in removable mode.
SDXC cards are not supported.
Are all the connection cables connected correctly?
If the camera is not recognized, turn the VR-24 off and thenon again.
To record 30fps HD video, connect a camera that supports
HD resolution to CAMERA-1.
When the sampling frequency is set to 96 kHz or 102.4 kHz,set the Analog settings “Record channel count” and CAN,
GPS and pulse channels so that the total number of channels does not exceed 4.
Enabling these inputs will use the following number ofchannels.
CAN: 2 channels
GPS: 1 channel
Pulse: 1 channel
Possible setting combinations when the sampling frequency
is set to 96 or 102.4 kHz
