Technical Information 1-15
Infrared Interface
The I/O controller incorporates an infrared interface that provides two-way wireless
communication through the IR window (port) on the front of the system. The interface uses
infrared as the transmission medium instead of a traditional serial cable.
The IR port permits transfer of files to or from portable devices such as laptops and
personal digital assistant (PDA) products using Puma TranXit applications software
(Windows 95 only) or other software supporting IrDA data transfer. The port supports data
transfers at 115 Kbps from a distance of 1 meter (3 feet 3 inches).
The IR port uses the system’s COM2 serial port to transfer data. The port shares registers
and function logic with COM2.
Universal Serial Bus Interface
The system board features two USB ports that permit the direct connection of two USB
peripherals, one to each port. For more than two USB devices, connect an external hub to
either of the built-in ports. The system board fully supports the universal host controller
interface (UHCI) and uses software drivers that are UHCI-compatible. The USB includes
the following features:
Self-identifying peripherals that can be hot-plugged
Automatic mapping of function to driver and configuration
Support for synchronous and asynchronous transfer types over the same set of
wires
Guaranteed bandwidth and low latencies appropriate for telephony, audio, and
other applications
Error handling and fault recovery mechanisms built into the protocol.
VIDEO BOARD
Depending on the model, the system features either a Matrox Mystique™ or a Number
Nine Imagine 128 Series 2 video board that utilizes the PCI local bus. The vidoe board
contains a graphics accelerator that integrates true color, digital video, and 3D effects into a
single chip and supports 2 MB (Matrox Mystique) or 4 MB (Number Nine Imagine) of
video memory. The 3D graphics engine renders 3D applications in photo-realistic colors
and textures for manipulatation in real time.
In addition to the standard VGA connector, a video feature connector is supplied on the
Matrox Mystique video board. The following subsections provide information about the
graphics features.
