Ⅰ Overview・Specification
1. Overview
【Script version】
The SD logger “script version” is a device whose basic function is to save data
received from serial communication (RS-232C) to an SD card.
Data stored on the card can be read out on a PC using a commercially available
card reader.
In addition to basic functions, functions can be expanded by writing scripts in
their own scripting language.
It is possible to send a specific command at regular intervals, or send specific data
in response to some reception. A simple communication protocol can be realized.
It also has a date / time function. The script can write the date and time to the log
file.
Part of the written script can be simulated on a personal computer using the free
software "CMLogger" provided by our company.
After confirming the operation on the personal computer, it can be implemented
in the SD logger “script version”.
Please refer to the following documents for the script language specifications.
「SD logger script language reference format (X507018)」
「SD logger script language tutorial format (X50701 )」
【Command version】
The SD logger “Command Version” is a device that can read and write SD card file
data by exchanging commands via serial communication (RS-232C).
Card data can be read and written by a personal computer using a commercially
available card reader.
Refer to the following document for command specifications.
「SD logger (command version) Command communication specification (X507016)」
「SD logger (command version) command reference (X507017)」
「Date / Time Command Reference (X51 005)」
※The SD logger can be switched between “script version” and “command version”
by changing the setting in “configuration mode”.
※Free software provided by our company can be downloaded from our website.

Ⅳ Usage procedure
1. Usage procedure
Procedure 1．Insert memory card
Insert a memory card into the logger.
Procedure 2．Power switch（POWER／SW2）ON
Turn the power switch to the [ON] side to turn on the power.
Setting the power switch to the [ON] side is expressed as 「Turn the power
switch ON」.
If the green LED (PL / LED1) turns on and the yellow LED (ACC / LED2) turns
off, the preparation is complete.
Procedure 3．Power switch（POWER／SW2）OFF
To finish the work after receiving data and exchanging commands, set the power
switch to the [OFF] side.
Setting the power switch to the [OFF] side is expressed as 「Turning the power
switch off」. The power turns off automatically after closing the open file.
＊It is possible to remove the memory card.
If the card is being accessed, it may take some time before the power is actually
turned off even if the power switch is turned off.
Check the card access with the yellow LED display.
Check that all LEDs are off before inserting or removing the card.

The buzzer sounds as follows.
Buzzer
When the access lamp（Yellow、 ）starts to light,
it sounds briefly.
※Does not sound when the configuration mode
is blinking.
Sounds the same as the blinking error lamp （Red、 ）
※Does not sound when flashing in update mode.
The buzzer can be stopped by removing the jumper switch, J3. See section 「Ⅶ.2」
for how to remove the jumper switch.

Ⅴ File
1. File control system
Logger uses the FatFs file system created by ChaN.I would like to thank and
thank Mr. ChaN for providing a competent file system.
Long file names are not supported.
2. Logging file 【Script version】
File name ［4-digit hexadecimal number］．ＬＯＧ
（Example）
0000.LOG
0001.LOG
0002.LOG
The logging file has a name that does not overlap with an existing file.
Search for the existence of the file from "0000.LOG" to "FFFF.LOG", and the
name of the first non-existent file found is used as the logging file name.
※The extension can be changed by script.
3. Subdirectory
In the case of "script version", the following subdirectory function works.
If a directory called 「LOGDATA」 exists in the root directory, a logging file will be
created under that directory.
If there is no "LOGDATA" directory, the logging file will be created in the root
directory.
The “command version” does not have a subdirectory function.

SD Logger４ instruction manual[X51 00 -3]
18/28 <2020/03/03> （3rd edition）
4. Maximum number of files
The maximum number of files that can be logged by the logger is 65536 [* 1].
However, in general, only 512 [* 2] files can be created in the FAT16 root directory,
so the logger also conforms to this restriction.
It seems that the maximum number of files that can be created in a subdirectory
is generally limited to 65534 [* 2], but the logger can create more than 65535 [* 2]
files.
And in our verification, the 65535th and 65536th files created by the logger can
also be read on a personal computer.
[*1] The maximum number of logging files created by the logger.
[*2] This is the maximum number including files other than logging files.
Start-up time
If there are many files on the card, it takes time to start up, which is not practical.
The following table gives an estimate of the startup time for the number of files
under certain conditions.
Number of
files
512pcs 1,024pcs 4,0 6pcs 10,000pcs
Start-up time 1.3seconds 2.1 seconds 16. seconds 1minutes
2 .6 seconds
※It is a reference value , not a guaranteed value.
5. Command version file specification 【Command version】
File name 8 single-byte alphanumeric characters + 3 character extension
（Long file names are not supported）
For details on the file names that can be handled by the command version,
See「Command Communication Specifications」.
The subdirectory function cannot be used in the command version.
6. Script file 【Script version】
In the case of “script version”, if there is a file named 「SCRIPT.TXT」 or
「SCRIPT.SCR」 on the installed memory card, it will be read as a script file.
The script file is read and executed when the power switch is turned on and the
power is turned on.
Script files are read from the root directory even if the directory “LOGDATA”
exists.
In the script file, LF (0x0A) is judged as the end of the line.
CR (0x0D) appearing in the script file is ignored.

SD Logger４ instruction manual[X51 00 -3]
1 /28 <2020/03/03> （3rd edition）
7. Writing speed
As the amount of data in the card increases, the writing speed decreases, which is
not practical.If writing speed is required, it is recommended that you use a card that
has just been formatted or has not recorded much data.
Consider using flow control for use with large amounts of data. In the command
version, check the response firmly (it takes longer time to get a response).
Notes
If it takes time to write 1 byte, the power will not be turned off immediately even
if the power switch is turned off.
Depending on the situation, the power may not be turned off for more than 1
minute even if the power switch is turned off.
In such a case, please wait for the card to be inserted or removed or the main
power supply to be shut off until all LEDs turn off even if the power switch is turned
off.

SD Logger４ instruction manual[X51 00 -3]
20/28 <2020/03/03> （3rd edition）
Ⅵ Response to power shutdown
1. Auto sync function
When data is lost for 3 seconds, the data remaining in the buffer is written to the
card and the consistency of the file structure is restored.
As a result, data received more than 3 seconds ago will not be lost even if the
power is suddenly shut down.
In addition, even if the power supply is cut off without receiving data for more
than 3 seconds, the file structure will not be damaged.
2. Capacitor backup
Even if the external power supply is cut off, the internal power supply is
secured by the capacitor.
Even if the power supply (main power supply) to the DC power connector is cut off
while the power switch is ON, the power is supplied from the backup capacitor and
the shutdown process is performed.
When the shutdown process is completed, the logger will cut off the power supply
to itself.
Power is supplied from the backup capacitor for a short time during the shutdown
process.
Even if the external power supply is suddenly cut off due to auto sync and
capacitor backup, the possibility of damaging the file structure is low.
Notes
The time required for the shutdown process varies depending on the usage
conditions of the card used.
On the other hand, the backup time with a capacitor is limited.
Please fully verify the effectiveness under the conditions of use.
