IR (Infra-Red) Support
The IN440EX I/O subsystem incorporates an IR interface supporting the following
industry standards; Fast IR, IRDA (HP-SIR), ASK-IR. The IR header provides the
necessary signal interface allowing a two-way wireless communication port using
infrared as the transmission medium. The user can transfer files to/from portable
devices such as laptops, PDA’s and printers using application software such as
LapLink. The Fast IR specification provides for data transfers at 4 Mbps from a
distance of 1 meter. This implementation also provides an infrared interface supporting
a standard or custom remote control device to perform wireless keyboard or mouse
functions.
IRDA Header (J19)
A header is available on the IRDA header for a cable connection to the IR module.
Miscellaneous Connectors
PC Speaker Connector
A header is available on the Speaker header (J22), pin 1 and pin 4 to drive a chassis-
mounted speaker if desired.
CPU Fan Connector
A 1 x 3 straight header is available on the PWA to drive the CPU mounted cooling fan
and provide the system with the Fan’s tachometer input.
