POD-6552 A2 User Manual 14
2.2.2.3 VGA connector (CN7)
The DB15-pin female connector is provided for video monitors.
2.2.2.4 Audio Connector (CN8)
The Audio link is a 2x8 pin connector, the POD-6552 can support speaker-out, Line-
IN, Line-out with Realtek ALC202, AC97 stereo sound. Detailed pin assignment refer
to Appendix A. AC'97 (short for Audio Codec' 97; also MC' 97, short for Modem
Codec' 97) is Intel Corporation's Audio "Codec" standard developed by the Intel
Architecture Labs in 1997, and used mainly in motherboards, modems, and sound
cards.
2.2.2.5 IR connector (CN10)
This connector supports the optional wireless infrared transmitting and receiving
module. This module mounts on the system case. You must configure the setting
through BIOS setup.
2.2.2.6 PS/2 keyboard and mouse connector (CN13)
PS/2 name comes from the IBM Personal System/2 series of personal computers,
with which it was introduced in 1987. The PS/2 mouse connector generally replaced
the older DE-9 RS-232 "serial mouse" connector, while the keyboard connector
replaced the larger 5-pin DIN used in the IBM PC/AT design.
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 fail during
power-on selftest (POST) after a reset. The POD-6552’s BIOS standard setup menu
allows you to select "All, But Keyboard"under the "Halt On" selection.
This allows no-keyboard operation in embedded system applications, without the
system halting under POST.
2.2.2.7 LVDS connector (CN14)
Low-voltage differential signaling, or LVDS, is an electrical signaling system that can
run at very high speeds over inexpensive twisted-pair copper cables. LVDS is a dif-
ferential signaling system, which means that it transmits two different voltages which
are compared at the receiver. LVDS uses this difference in voltage between the two
wires to encode the information.
POD-6552 uses the Intel 852GM to supports single or dual-channel LVDS panels up
to UXGA panel resolution with frequency range from 25 MHz to 112 MHz. Users can
connector to 18-bit LVDS LCD with CN14. In addtion, POD-6552 can support 2 chan-
nels (2 x 18-bit) LVDS LCD panel (optional).
2.2.2.8 Inverter Connecter (CN15)
POD-6552 can p5 V and +12 V and signal to LCD inverter board via CN15.
2.2.2.9 Audio CD-In Connector (CN16)
CD In cable used to send audio CD sound to the computer's audio chipset via CN16.
2.2.2.10 TTL Panel Connector (CN17)
CN17 is a 40-pin connector for TTL LCD or DSTN. It could connect TTL LCD or
DSTN freely to meet your need.
2.2.2.11 PC-104 connector (CN18)
POD-6552 supports a PC-104 connector. It is intended for industrial embedded com-
puting environments where applications depend on reliable data acquisition.
