E Infra-Red (IR) Header
The Mainboard provides a 5-pin header interface, IR
for connection to a Hewlett Packard HSDSL-1000 compatible
infrared (IrDA) transmitter/receiver. Connect IR to the front panel
I/O IrDA connector provided with your system. Once the module
is connected to the front panel I/O IrDA connector, 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 115 kbps from a distance of 1-meter. Support for Consumer
infrared (ASK-IR) is also included. Please refer to your IR
equipment for more detailed information.
The header pin-out is as follows:
Pin . . . . . . . . . . . . . Signal Name
1 . . . . . . . . . . . . . . . VCC, power source
2 . . . . . . . . . . . . . . . No Connection
3 . . . . . . . . . . . . . . . IRRX, infra-red receive
4 . . . . . . . . . . . . . . . Ground
5 . . . . . . . . . . . . . . . IRTX, infra-red transmit
F Memory Module Sockets
The Mainboard provides 168 pin standard DIMM sockets for
installation of 3.3V unbuffered Single or Double Bank SDRAM
modules.
G Parallel Port onnector
The ATX Mainboard provides a parallel port connector. Based
on the ATX standard, a 25-pin parallel port is now built on
the mainboard back panel. This design makes the mainboard
installation easier. The parallel port can be BIOS configured
into standard (SPP) mode, Enhanced Parallel Port (EPP) mode,
and a high speed Extended Capabilities Port (ECP) mode. EPP
Mode requires a driver provided by the peripheral manufacturer
in order to operate properly.
