2.11 Keyboard and PS/2 mouse connector

The PCM-3345 board provides a pin head keyboard connector, which

supports both a keyboard and a PS/2 style mouse. In most cases,

especially in embedded applications, a keyboard is not used. If the

keyboard is not present, the standard PC/AT BIOS will report an error

or failure during the power-on self test (POST) after resetting the PC.

The PCM-3345 board's BIOS standard setup menu allows you to

select "Absent/Present" for your keyboard under the Advanced CMOS

Setup section. This allows non-keyboard operation in embedded

system applications without the system halting during the POST.

When "PS/2 mouse support" is enabled, your PS/2 mouse is automati-

cally detected by the system.

Supplies main power to the PCM-3345 (+5 V) and devices that

require +12 V.

Supplies secondary power to peripherals that require -5 V and

-12 V.

The PCM-3345 provides an IrDA port for transfer rates of 115 kbps.

This connector supports the optional wireless infrared transmitting

and receiving module, which is mounted on the system case. Configu-

ration of the module is done through BIOS setup. You must also

configure the setting through "IR Port Support" in Peripheral Setup

to select whether UART2 is directed for use with COM2 or IrDA. Use

the five pins as shown in Appendix A, and connect a ribbon cable

from the module to the CPU board according to the pin assignments.
