2.6 AC’97 Audio Codec Controller
The integrated AC’97 Audio compliant audio controller on the Intel® ICH7M Southbridge
is integrated to a Realtek ALC888 audio codec. The Realtek ALC888 is connected to an
amplifier which powers the two 1.5 Watt speakers.
2.7 System Power
The system can be run in the AT power mode or the ATX power mode. Both these power
modes are described below.
2.7.1.1 ATX Power Mode (Default)
With the ATX mode selected, the AFL-4 Series-N270 panel PC goes in a standby mode
when it is turned off. The panel PC can be easily turned on via network or a power switch
in standby mode. Remote power control is perfect for advertising applications since the
broadcasting time for each panel PC can be set individually and controlled remotely. Other
possible application includes
Security
surveillance
Point-of-Sale
(POS)
Advertising
terminal
2.7.1.2 AT Power Mode
With the AT mode selected, the power is controlled by a central power unit rather than a
power switch. The AFL-4 Series-N270 panel PC turns on automatically when the power is
connected. The AT mode benefits a production line to control multiple panel PCs from a
central management center and other applications including:
ATM
Self-service
kiosk
Plant environment monitoring system
Factory automation platform
Manufacturing shop flow
