Hardware Configuration
802.11 b/g and a/b/g Wireless Client
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. WEP, WPA and LEAP are supported.
Central Processing Unit
The CPU is a 806 MHz Marvell PXA-320 CPU. The OS image is stored in on-board flash memory. The MX9 supports the
following I/O components of the core logic:
• One serial port (DTE) with appropriate power for a WAN radio
• One serial port (DTE) for an integrated laser decoder with ring indicator (RI )
• USB 1.1 Host (capable) with power (5V @ 500mA)
• One SSP port (capable, not implemented)
• One SDIO port for I/O expansion (capable)
• One SIM port for WAN
• One serial port (DTE) for interface with GPS receiver chip
• Non-decoding imager
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 for storage of operating system and program code, as well as persistent storage.
The internal SD flash card appears to the OS as a folder. This allows the contents to be manipulated via the standard Win-
dows interface.
Video Subsystem
The touch screen display supports QVGA and 16 bit color depth, and is readable indoors or outdoors even in direct sunlight.
The display is transflective active-matrix TFT and has an LED backlight.
A tethered stylus is included. The touch screen surface can be activated with the stylus or a gloved or bare finger.
The Cold Storage option includes a touch screen heater and a scan aperture heater to eliminate condensation. The heaters can
be enabled or disabled by the user. Once enabled, the heaters will turn on whenever the ambient temperature warrants, for
example, when moving into and out of freezers or refrigerated buildings.
Power Supply
The MX9 uses one of two batteries for operation. A Lithium-Ion (Li-Ion) standard battery has a 2400 mAh capacity. Low
temperature Lithium-Ion (Li-Ion) batteries have a 2100 mAh capacity.
