Central Processing Unit
The LXE MX3-CE CPU is a SA1110 running at 133MHz or 206 MHz.
Core Logic
The MX3-CE supports the following I/O components of the core logic:
•
One PCMCIA slot (supports Type II or III PCMCIA cards).
•
One compact Flash card port (supports Type I and II cards).
•
One InfraRed port.
•
One Digitizer Input port (Touch screen).
•
Two serial ports in four configurations (see Chapter 1 "Introduction" section titled
"Endcaps.").
Note: As the MX3-CE does not have PC Card Management software installed, LXE
recommends purchasing pre-formatted cards.
System Memory
On-board FLASH is used for ROM, Flash for WindowsCE and Flash memory for bundled
applications. Pads are available for 16 MB or 32 MB of Flash. The Flash is configured as the
primary boot device and contains the Windows CE image, boot loader, OAL, applications,
utilities and device drivers.
Any flash remaining beyond the Windows CE image is formatted for use as a persistent memory
drive (which appears in My Computer as the folder IPSM). Any programs or data stored in this
folder will not be lost if the memory backup battery fails. Currently, the persistent memory drive
partition is from 3.7 to 21 MB in size, depending on the amount of flash available and options in
the Windows CE image.
The computer has one Type II CF+ slot. The MX3-CE supports and auto detects up to 256MB of
Type I compact flash memory.
Video Subsystem
The display has a 640 pixel (horizontal) by 240 pixel (vertical) format. The display contrast is
adjustable with key sequences. Backlighting is available, can be turned on and off with key
sequences. The turn-off timing is configured through the Control Panel. The display controller
supports Windows CE graphics modes.
Touch screen allows mouse functions (pointing and clicking on the display or Signature Capture)
using an LXE approved stylus.
There are three types of displays available: transflective greyscale monochrome; transmissive
color and transflective color.
The transmissive color display is optimized for indoor lighting. It cannot be used without the
backlight. The transflective monochrome and color display are optimized for outdoor use but may
also be used indoors. The monochrome display has an electroluminescent backlight. The color
displays have a CCFL (Cold-Cathode Fluorescent Lighting) backlight.
The transflective display appears to have a greenish hue when the display is blanked. The
transmissive display appears black when the display is blanked.
