VT-502 Mainboard Manual

Serial Infrared (SIR) Connections

This mainboard features support for highly-sophisticated SIR technology,
which allows bi-directional and cordless data transactions with other IrDA
compliant computers and peripheral devices using infrared as a medium.
This transmission is carried out in either Full Duplex Mode or Half Duplex
Mode. The former allows simultaneous data transmission and reception,
while the latter disables the reception when transmission occurs.
The I/O chipset on this mainboard features a SIR interface that is fully
compliant with the IrDA standard. An IrDA device can be installed via a 9-
pin D-SUB connector in the rear panel of the computer which is linked by a
cable to the onboard IrDA pinhead.
The serial port COM2 on this mainboard is designed to be an SIR compliant
port. If you wish to install the SIR connection feature, you need to adjust the
BIOS option for high-speed performance.

Universal Serial Bus (USB) Functionality

USB overcomes conventional I/O bottlenecks by combining the I/O ports
into a single dual-channel connector. For optimum ease of use and
flexibility, USB not only allows the automatic detection and configuration of
peripherals after installation, but also enables the simultaneous connection.
This mainboard features an optional USB riser card (see the photo below)
with bracket that can be installed in one of the I/O expansion slots on the
rear panel of the system, as shown in the illustration below. It provides fast
and convenient Plug and Play peripheral connections outside your
computer, allowing you take full advantage of the universal functionality
and flexibility of USB technology.
