IR Connector (CN1)

This connector supports the optional wireless infrared transmitting

and receiving module. This module mounts on the system case. You

must configure the setting through the BIOS setup.

In addition the the PS/2 mouse/keyboard connector on the

PCA-6175's rear plate, there is also an extra on-board external

keyboard connector. This gives system integrators greater flexibility

in designing their systems.

This allows the user to manually place the system into a suspend

mode or "Green" mode when the system is not in use. System activity

is decreased to save electricity and prolong the life of certain

components. The 2-pin connector connects to the case-mounted

suspend switch. If you do not have a switch for the connector, you

may use the "turbo switch", because it does not have any other

function. SMI is activated when it detects a "short to open" moment.

Therefore, leaving it shorted will not cause any problems. It may

require one or two pushes depending on the position of the switch.

Wake-up can be controlled by settings in the BIOS, but the keyboard

will always allow wake-up. (The SMI lead cannot wake up the

system.) If you want to use the SMI connector, the "Suspend" switch

in the Power Management Setup of the BIOS software should be on

the default setting "Enable".
