Introduction

The PCA-6742 is the ultimate cost-effective solution for limited space applications. It
offers all the functions of an AT-compatible industrial computer on a single board. The
new CPU module supports Advantech EVA-X4300 SOC (system on chip) which sup-
ports ISA interfaces.
On-board features include a 10/100 Ethernet interface, Compact Flash socket (Type
I/II) shared with secondary IDE, Enhanced IDE interface, one parallel port, four serial
ports (1*RS232 on rear I/O, 2*RS232, 1*RS232/422/485), and a PS/2 keyboard/
mouse interface. An SVGA/LCD display controller (LCD and CRT displays) allows
LCD screen resolutions up to 1024 x 768 @ 18/24 bit LVDS/TTL (Optional) and CRT
resolutions up to 1024 x 768 @ 24bit true color.
The PCA-6742 complies with the "Green Function" standard and supports three
types of power saving features: Normal, Doze and
Sleep modes.
If you need any additional functions, the PCA-6742 has a PC/104 connector for
future upgrades.
