System Hardware

802.11b/g and a/b/g Wireless Client

The MX8 has an 802.11 network card that supports diversity with two internal antennas. The CPU board does not allow hot
swapping the network card. Adjusting 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 520MHz PXA27X CPU. The operating system is Microsoft® Windows® Mobile 6.5. The OS image is stored
on an internal flash memory card and is loaded into DRAM for execution. Turbo mode switching is supported and turned on
by default.
The MX8 supports the following I/O components of the core logic:
• One mini SD card slot under the main battery pack.
• One serial port.
• One Digitizer Input port (touch screen).

System Memory

The CPU configuration supports 128MB Strata Flash, 128MB SDRAM. The system optimizes for the amount of SDRAM
available.
Internal flash is used for boot loader code and system low-level diagnostics code. Bootloader code is validated at system
startup. The UUID required by the Windows OS 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 Mini SD Memory Card

The MX8 has one mini SD card interface for storage for User data. The mini SD slot is accessible from the battery
compartment and ships with a qualified 128MB Mini SD Flash card.
The internal mini SD flash card supports a FAT16 file system, via a special device driver, and appears to the OS as a folder.
This allows the contents to be manipulated via the standard Windows interface.

Video Subsystem

The touch screen is a 2.8" (7.1 cm) diagonal viewing area, ¼ VGA 320 by 240 pixel TFT Transmissive Active Color LCD.
Backlighting is available and can be turned on and off with key sequences. The turn-off timing is configured through the
Start > Settings > Control Panel > Display > Backlight icon. The display controller supports Microsoft graphics modes.
A touch screen allows mouse functions (tapping on the display or signature capture) using a stylus. The touch screen has
an actuation force with finger less than 100 grams. The color display has an LED backlight and is optimized for indoor use.
The display appears black when the MX8 is in Suspend Mode.

Power Supply

The MX8 uses two batteries for operation.
Main Battery
A replaceable 3000 mAh Lithium-Ion (Li-Ion) battery pack. The battery pack recharges while in the MX8 when the device is
connected to the optional external MX8 AC/DC power source. The main battery pack can be removed from the MX8 and
inserted in the MX8 Multi- Charger which simultaneously charges up to four battery packs in five hours. The MX8 status
indicator is illuminated when the backup battery is being charged by the main battery pack. A new main battery pack can be
fully charged in 5 hours when it is in an MX8 connected to AC power and 5 hours when it is in the MX8 battery charger.
