Preparing to Update the xPico 200 Series Before loading the Manufacturing Test Loader or updating the bootloader, perform the following:  Set the xPico 200 module's line settings to 115200 bps, 8 data bits, no parity bit, 1 stop bit, and hardware flow control.  Set your terminal application to the same serial settings.  Connect the xPico 200 module to the PC using a serial cable.  Acquire the latest Manufacturing Test Loader .rom file.  Acquire the latest bootloader .rom file.
