2.5.1. RS-422/RS-485 specifications
- Transmission system: Asynchronous, half-/full-duplex serial
transmission conforming to RS-422/RS-485
- Baud rate: 19200 to 50bpx (programmable)
- Signal extensible distance: 1.2km Max.
Note: The mouse and keyboard can be plugged into either PS/2 connector. Power to
should be turned off before a keyboard or mouse is connected or disconnected.
The keyboard controller contains code, which provides the traditional
keyboard and mouse control functions, and also supports Power On/Reset password
protection. A Power On/Reset password can be specified in the BIOS Setup
program.
The keyboard controller also supports the hot-key sequence
<Ctrl><Alt><Del>, software reset. This key sequence resets the computer’s
software by jumping to the beginning of the BIOS code and running the Power On
Self Test (POST).
Infrared Support
On the front panel I/O connector, there are six pins that support Hewlett
Packard HSDL-1000 compatible infrared (IR) transmitters and receivers. In the
Setup program, Serial Port B can be directed to a connected IR device. (In this case,
the serial Port B connector cannot be used.) The IR connection can be used to
transfer files to or from portable devices like laptops, PDAs, and printers. The
Infrared Data Association (IrDA) specification supports data transfers of 115
Kbit/sec at a distance of 1 meter.
Consumer Infrared Support
On the front panel I/O connector, there is one pin that supports consumer
infrared devices (remote controls). This pin supports receive-only operations at
data rates of up to 685.57 Kbit/sec.
Consumer infrared devices can be used to control telephony and multimedia
operations, such as volume or CD track changes. A software and hardware
interface is needed for a computer to support the consumer infrared feature.
