When applying the SV2000E image card, be careful to select a driver with the same output port number as the CCD data signal when installing the driver, and pay attention to whether the computer operating system is a 32-bit system or a 64-bit system.
4. The port number method in the config file has been changed. Specific method: Right click on the software icon, "Open in Source File", search for the config file - sysparam, double-click the mouse to open the file. When using an SDk2000 card, 0=PIC, 1=USB in the config file? Type=0. If using SV2000E card, Type=10? 5. Image settings in mobile software???
