Use Demonstration: Use your fingernail to open the expansion board interface snap upwards, the flat cable is inserted face to face with the expansion board interface to flatten, and then the snap to hold the FPC that the installation is complete. Interface Description: The socket of this TF expansion board is 12PIN. Therefore it can be connected to XM IPCs with 12PIN sockets, such as IVG-N8S, IVG-N8F, IVG-G6S, IVG-G5F and IVG-G3S. For the TF storage function, when connecting the expansion board to the IPC, you do not need to upgrade the firmware of the IPC to support the storage function. WIFI Function: For wifi function, it can only support work with IVG-G3S, IVG-G4F-A modules. And before connecting these 3 modules, you need to upgrade the custom program of 'wifi support' for the IPC module. Except for IVG-G3S, IVG-G4F-A, which are 2 kinds of modules, the expansion board can't realize wifi function with other modules. Because XM's other IPC modules don't have a custom program that supports 'wifi function', there is no way to implement wifi function even after you connect it.
