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.

onboard for the connection to the three (3) display types:
1. CRT VGA monitors

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.
