The MX9 has an 802.11x network card that supports diversity with two internal antennas. The CPU board does not allow hot
swapping the network card. Power management on the network card is set to static dynamic control.
WEP, WPA and LEAP are supported.
Central Processing Unit
The CPU is a 806 MHz Marvell PXA-320 CPU. The operating system is Microsoft Windows Mobile 6.5. The OS image is
stored in on-board flash memory.

System Memory
The MX9 supports 128 MB on-board RAM and 128 MB on-board Flash. Operating system and boot loader software image
update is supported via expansion card and remote management via radio.
Internal flash is used for boot loader code and system low-level diagnostics code. Bootloader code is validated at system
startup. The UUID is stored in the boot flash. A second copy of the bootloader code is stored on the internal SD Flash drive, so
that if a damaged bootloader is detected, it may be re-flashed correctly.
Internal SD Memory Card
The MX9 has one
SD card interface
The internal SD flash card appears to the OS as a folder (Storage Card). This allows the contents to be manipulated via the
standard Windows interface.
for storage of operating system and program code, as well as persistent storage.
