Technical Information 1-21
Infrared Interface
The I/O controller incorporates an infrared interface that provides two-way wireless
communication through the IrDA window (port) on the front of the system. The interface
uses infrared as the transmission medium instead of a traditional serial cable.
The IrDA port permits the transfer of files to or from portable devices such as laptops and
personal digital assistant (PDA) products using the pre-installed LapLink
applications
software or other software supporting IrDA data transfer. The port supports data transfers
at 115.2 Kbps from a distance of 1 meter (3 feet 3 inches).
The IrDA port uses the system’s COM2 serial port to transfer data. The port shares
registers and function logic with COM2. Note that COM2 is disabled by default, so it must
be enabled before the IrDA port can be used. Enable COM2 from the Advanced menu of
the BIOS Setup utility, under the Serial Port B submenu, and set Serial Port B Mode to
IrDA.
Graphics Capabilities
The system supports accelerated graphics port (AGP) and PCI graphics boards.
A PCI graphics board installs in one of the computer’s PCI expansion slots.
An AGP graphics board installs in the system board’s AGP connector.
The following graphics boards are available from NECCSD:
ATI XPERT@Work AGP 2X graphics board
This board contains 4 MB of Synchronous Graphics random-access memory
(SDRAM), upgradeable to 8 MB using a daughter card.
Cirrus Logic DM-5465 AGP graphics board
This board contains 2 MB of video memory.
Number Nine Revolution III PCI graphics board
This board contains 4 MB of video memory, upgradeable to 8 MB or 12 MB
using a 4-MB or 8-MB WRAM daughter card.
To use the system’s graphics capabilities with a display monitor, order one of the video
boards listed above or install another compatible video board of your choice.
To view photorealistic images, enhance presentation graphics, and view TV-quality MPEG
video, install a standard VGA-compatible monitor to the PCI or AGP graphics board’s
external VGA monitor connector.
