4.7 SD Card Interface
The device provides one SD card interface, which supports a maximum of 64 GB SD
memory card for storing CAN bus message data. The interface adopts a self-locking card
slot, and the SD card can be locked after the card is inserted according to the direction of
the casing logo to prevent accidental falling off during use. When pulling out the card, just
push it inwards to eject the SD card.
The SD card uses the EXT4 file system. Connecting the SD card through a card
reader cannot directly view the SD card data in the Windows system. You need to install a
tool plug-in that supports the EXT file system (for example, Ext2Fsd).
Note: Do not forcibly pull out the card during the device operation; otherwise, it
may cause data loss or damage to the memory card and device exceptions! If
necessary, after powering off the device, open the SD card slot cover, push in
gently and eject the SD card.
