Overview
The VARIOLITE is a powerful slim-line Intel Pentium P4-based Personal Computer (PC) specifically designed
to drive large plasma and other large displays panels. The unit is self-contained requiring as a minimum, only a
power connection and a display. The applications are not limited to display applications: it may be used as a
general purpose PC.
The basic unit comprises a highly integrated computer board employing Intel’s 845G chipset that supports Intel
Pentium 4 processors up to 3GHz (where available) with 400 MHz and 533MHz front side bus (FSB). Memory
options allow up to 2GB of ultra fast PC1600/PC2100 DDR SDRAM. A single 2½-inch ATA-100 hard disk
drive, or optional Compact Flash, provides storage
The on-board Intel Extreme Graphics features Dynamic Video Technology and Zone Rendering Technology to
deliver unrivalled 2D and 3D 16:9 performance with a wide range of resolutions. Displays may be driven in
landscape or portrait modes.
The on-board audio system may be configured from simple stereo to a full 5.1 surround system. The addition of
a programmable hardware watchdog provides security against an application malfunction.
The unit is housed in a strong sheet-steel enclosure providing both mechanical and EMC protection. A fan
draws cooling air into the unit and directs it through the chassis to ensure a wide operating temperature range.
The unit may be mounted on a wall, the plasma display, or separately to suit the particular installation. A
mounting kit is available for wall mounting.
Most connectors are on the rear face of the chassis. There are connectors for a PS/2 mouse and keyboard, a
standard analogue VGA display, two serial ports, a parallel port, two USB (2.0) ports, an Ethernet (10/100) LAN
port, and three audio connectors. The LAN connector also includes LEDs indicating a connection and data rate.
The rear face of the chassis also includes the AC power inlet connector. The power supply unit has an auto-
ranging AC input to cover most geographic markets.
Indicators and controls on the front face of the chassis are limited to a hard drive activity LED, a power on LED
and a power standby pushbutton switch. There are also two USB (2.0) ports in addition to those on the rear
panel.
