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.
2. Variation This instruction manual explains the following models of the SD logger. Model Name Factory function Exterior (Basic version) ESD-CS4A SDlogger4 Script version Case ESD-CC4A SDlogger4 Command version Case ESD-BS4A SDlogger4 Script version ESD-BC4A SDlogger4 Command version ※The “script version” includes the functions of the original “normal version”. 3.

Ⅱ Setting 1. DIP switch setting and configuration setting SD Logger 4 has a function that can be switched by DIP switch setting and a function that can be switched by configuration setting. Configuration settings are made by connecting to a PC. For configuration settings, refer to “Chapter I-3”.

Ⅲ Connection 1. RS-232C cable connection Check each signal so that there is no mistake in the connection of the RS-232C connector. The connector pin assignments are as follows. RS-232C D-Sub 9pin male (View from connector mating surface) Pin No. Name Contents Signal direction...
2. Power supply Supply DC power (DC8V to 12V) from the DC power connector (DC jack, CN2 for board). Use a compatible DC plug with an inner diameter of φ2.1 and an outer diameter of φ5.5. When using an AC adapter, select a suitable DC plug. When using an AC adapter, the switching regulator type is recommended.
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」.
2. LED display / buzzer sound The LED is displayed as follows. Pilot lamp (Green) Lighting Power is on. PL/LED1 Access lamp (Yellow) Accessing the memory card. Lighting Holding data in the buffer. ACC/LED2 Flashing In configuration mode. Flashes once The card is not installed.
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. 【Script version】 2. Logging file [4-digit hexadecimal number].LOG...
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.
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.
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.
Ⅶ Other functions 1. Date / time setting To set the date and time, connect the logger to a PC and execute the PC dedicated software (SDLG4_TADJ). For details, please refer to the separate document 「Date / Time Setting Instruction Manual <X520012>」. Check the date and time settings after purchase and before use.

3. Flow control By enabling the setting by changing the setting in the configuration mode, flow control using the RTS signal can be performed. When the flow control is enabled, the RTS signal is turned off when the reception buffer in the logger is running low, and is turned on when the remaining capacity is high.
Ⅷ Enhanced function・Difference from logger 3 SD logger 4 has the following enhanced functions compared to conventional SD logger 3. 1. A fast bit rate has been added. A bit rate of 115200 (bps) has been added. 2. Status file When the power is turned on, the status of the logger is written to the following status file.
3. Update from card By placing special files on the SD card to be installed, you can update your own internal programs. To perform the update, rename the update module file provided by our company (such as "DTMC04_X_VXXX_UDM.fu2") to the file name "UPDATE.FU2" and copy it to the root folder of the card.
7. Other enhancements The command version "Delete all files (E: *. *)" Command can be used even with FatFs (FAT32 compatible file system). (SD Flogger 3 only allowed FATSYS (conventional FAT16 file system)) Reading is now possible even when the write-protect tab is set to the write-protected position.
Ⅺ Notes / Others 1. Card Insertion and removal Turn off the power switch before inserting or removing a card, and make sure that all the LEDs are off. 2. Warranty The warranty period is one year after shipment. If the product breaks down under the correct usage conditions, the product will be repaired free of charge in accordance with the terms of this warranty.
