Chapter 2 Working with Hardware Devices
2.1 Usage of SD Card and USB Disk
 SD Card
SD card (supports SDHC) can be used to save and transmit data. The supporting file
format is FAT32. Before using a SD card, reformatting (FAT32) via HMI is needed. Only SD
card that formatted by HMI can be used on both HMI and Windows® OS system. (Even it
can be read/written in some format, but faults may occur due to different format among
Win95/98/2000/XP versions)
 USB Disk
USB disk can be used to save data. It also can be used to copy data from HMI and its
format is FAT32 as well. When using USB disk to save data, we recommend that the
storage capacity should be less than 2GB and the users should enter system screen first
and then remove the USB disk. Follow this process can ensure that the data is saved
completely in USB disk.
There are two kinds of methods for removing the USB disk:
1. Press SYS button for 3 seconds to enter intro the system setting screen. Then, the
users could choose the function to remove the USB disk.
2. Create a “Remove storage” button on the screen first. After settings and compile
operation is completed, pressing this button is able to remove the USB disk. For more
information on “Remove storage” button, please refer to section 3.8.2.7 in Chapter 3.
Please use the above two methods to remove the USB disk to ensure that the data is saved
completely in USB disk.
