Audio Interface

Audio Connector

AC’97 Audio signals are interfaced through a 10-pin flat-cable connector. These signals include

Microphone line-in, line-in stereo, and line-out stereo. An audio 10-pin-to-phone-jack adapter kit

is required.

COM Port Connectors [COM1(CN22), COM2/COM3(CN16)]

The WAFER-LX provides two serial ports (COM1: RS-232; COM2: RS-232/422/485) interfaced

through one DB-9 connector (COM1) and one 14-pin male header. These serial ports facilitate

the connection to serial devices or a communication network, e.g., terminal console.

LCD Panel Connection (CN26, CN28, and CN29)

The PCI SVGA interface on the WAFER-LX connects conventional CRT displays and flat panel

displays including passive LCD and active LCD displays. There are three (3) connectors

onboard for the connection to the three (3) display types:

1. CRT VGA monitors

2. TFT flat panel displays

3. LVDS type LCD panels

One CRT display connector (CN26) is provided as a 15-pin, female D-SUB to connect

conventional CRT displays. Pin assignments can be found in Chapter 2 Functional

Description.

Flat Panel Display Connector (CN28):

CN28 is a 40-pin connector, Hirose DF13A-40DP-1.25V, which can support a 24-bit LCD panel.

A bias control signal, ENVEE, active high on CN28, controls the LCD bias voltage. The LCD bias

voltage shall not be applied until the +5V or +3.3V logical supply and panel video signals become

stable. When powered on, the control signal remains low until receiving the flat panel signals.

CN28 connects up to 24-bit TFT LCD.
