Quick Reference of Your Motherboard
[A] AT Power Supply Connector
Based on the AT specification, one 12-pin power connector covers all the required power sources, ±5V
and ±12V.
[B] ATX Power Supply Connector
Based on the ATX specifications, one 20-pin power connector covers all the required power sources, ±5V,
±12V, and ±3.3V, with soft-touch button power on/off features. This connector reduces the installation
time and minimizes the chance of defects caused by incorrect connection.
[C] AT Keyboard Connector
This connection is used for a standard IBM-compatible keyboard, such as 101 enhanced keyboard.
[D] Serial (COM 1 and 2) Port Headers
This motherboard provides two high-speed UART compatible serial ports.
[E] Parallel (Printer) Port Connector
One Parallel port with SPP, EPP and ECP capabilities.
[F] Integrated Functions Connector
I) From Pin1 to Pin5 is the first USB device “USB1” and Pin11 to Pin15 is the second USB device
“USB2” connector. Universal Serial Bus (USB) is new interface standard for any I/O device
“Outside the Box”. USB makes your peripherals have a real plug and play (PnP) capabilities with
up to 12MB/sec data speed In the coming soon, any external device connected to your computer
will be standardized into USB standard which are all have a special 4-pin rectangle shape
connector. Therefore, with the Intel chipset, this motherboard builds two USB headers on-board
for you future investment. If you are using an USB device, you must purchase an optional USB
connector.
II) From Pin6-10 is the PS/2 device, likes some PS/2 keyboard and mouse, are all have a standard 6-
pin round shape connector. However, it does not have a unique onboard standard. Therefore,
please refer to the Chapter “Motherboard Installation”, in order to purchase an suitable PS/2
Mouse Connector.
III) From Pin16-20 is a 5-pin interface on the front panel I/O connector is provided to allow
connection to a Hewlett Packard HSDSL-1000 compatible Infra-red (IrDA) transmitter/receiver.
Once the module is connected to the front panel I/O header, Serial port 2 can be re-directed to the
IrDA module. When configured for IrDA, the user can transfer files to or from portable devices
such as laptops, PDA’s and printers using application software such as LapLink. The IrDA
specification provides for data transfers at 115kbps from a distance of 1 meter. Support for
Consumer Infra Red (ASK-IR) is also included, please refer to your IR equipment for more
detailed information.
[G] SDRAM Socket
There are two unbuffered, 3.3 Volts, SDRAM socket on-board provides more flexibility for your system
memory upgrade.
