Wi-Fi Continuous Mode Software Installation First download the Wi-Fi continuous mode software to use the module for continuous mode testing for certification. Once downloaded and powered up, you will no longer be able to load the standard Lantronix firmware and the module can only be used for continuous mode testing for certification. 1. Download the xPico 200 continuous mode software at https://www.lantronix.com/products/xpico-200/#docs-downloads/. 2. Copy the xPico200_continuous_tx directory to the desktop of your PC. 3. Connect the Olimex ARM_USB_Tiny_H adapter to your PC and UUT. Note: You will need the Tag-Connect adapter and cable to connect your Olimex to the JTAG port on the evaluation board. Required Tag Connect part numbers TC2050-ARM2010 and TC2050-IDC 4. Install the appropriate Zadig driver for the Olimex on your PC. 5. Open a command prompt and CD to this directory: \Desktop\xPico200_continuous_tx\firmware-711_NVRAM 6. Power up the unit and run the loadfw.bat script to load the continuous mode firmware. xPico® 200 Certification Firmware Instructions 7
