EV-DNG-RFMOD-9001Z provides an easy interface between the RF module (Lexiwave module which contains ADuCM3029 and ADF7023) and the PC, enabling the user to readily access all the peripherals and GPIOs on the RF module. The RF module can either be soldered down to the EV-DNG-RFMOD-9001Z USB Dongle through the castellations or it can be connected through hirose connector. A variety of modules like Lexiwave, Tessera, SG6T and Smartmesh modules can be connected through hirose as the standard pin layout is maintained for all the RF modules in COG ecosystem. The rapid 6LoWPAN module (Lexiwave module) is currently soldered down to the Dongle.
On EV-DNG-RFMOD-9001Z, FTDI chip, FT4232H is present. It provides four channels to interface with PC. Multi Protocol Synchronous Serial Engine (MPSSE) is present in channel A and channel B of FT4232H through which any serial communication interface can be emulated. The channel details are as given below:
For quick debugging purpose when hirose connector option is being used, following test points are provided,
