Back Panel Connectors
The back panel provides external access to PS/2 style keyboard and
mouse connectors, one serial port, one VGA port, one parallel port, dual
USB ports, one LAN port, and audio Line-out, Mic-in port which are
integrated on the mainboard. The figures below show the location of the
back panel I/O connectors.
PS/2 Mouse and PS/2 Keyboard Ports
Connect a PS/2 mouse to the green 6-pin mini DIN connector. The system
will automatically assign IRQ 12 to the PS/2 mouse if one is connected.
Connect a PS/2 keyboard to the purple 6-pin mini DIN connector. If you
want to connect a standard AT size (large DIN) connector, you must use
an adapter.
Universal Serial Bus Ports
You can connect two USB devices or USB hubs to the USB ports.
The USB ports provide a hardware interface for low-speed peripher-als
such as the keyboard, mouse, joystick, scanner, printer and telephony
devices, and also support MPEG-1 and MPEG-2 digital video. The USB
ports have a maximum bandwidth of 12 Mbits/sec (equivalent to 1.5
Mbytes/sec), and up to 127 devices can be attached. Fast devices can use
the full bandwidth, while lower-speed ones can transfer data using a 1.5
Mbits/sec sub-channel.
