Hardware Configuration

Video Subsystem

The LXE VX5 video subsystem consists of a color TFT display. The video subsystem complies
with the VESA VL bus standard. The resolution of this display is 800 by 600 pixels. This
resolution complies with the SVGA graphics industry standard.
The AGP video controller uses a portion of the system memory. As installed in the VX5, the
video controller uses about 2MB of system memory.

Power Supply

Vehicle power input for the VX5 is 12V to 80V DC nominal and is accepted without the need to
perform any manual operation within the VX5.
If 12V to 60V DC power is not available – for example, in an office environment – an optional
external Universal Input Power Supply can be used to convert AC wall power to an appropriate
DC level. See Chapter 3 "Power Supply", sub-section titled "External Power Supply."
Power input is fused for protection and the fuse is externally accessible.

Uninterruptible Power Supply

A DC uninterruptible power supply (UPS) battery is available to maintain power to the VX5 for a
minimum of 15 minutes when vehicle power is not available (such as when a vehicle battery is
being swapped).

Backup Battery

The LXE VX5 has a permanent lithium battery installed to maintain time, date and BIOS setup
information. The backup battery is not user serviceable and should last five years with normal use
before it requires replacement.
Note: This battery should only be changed by authorized service personnel.

PCMCIA Slots

Microsoft Windows Plug and Play operating system controls the CardBus/PCMCIA cards. These
cards are hot swappable per the CardBus/PCMCIA specifications.
The ATA slot is not hot swappable. The VX5 must be powered down to insert or remove an ATA
card.

Power Management

The VX5 uses Microsoft Windows Power Management. The VX5 has two operating modes:
Normal and Standby.
In Normal operating mode all systems are powered up and the video display is on. The RS-232
ports, any installed PCMCIA cards are active. However, Microsoft Windows also allows the
display and hard disks to be shut down in normal mode to conserve energy.
The Standby mode shuts down many devices such as the display and hard drives. For complete
details on the standby mode, please refer to the Microsoft Windows help screens.
