2 PCA-6740 User's Manual
1.1 Introduction
The PCA-6740 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 PCA-6740 comes with
an embedded high-performance STPC Elite 133 processor and
32MB SDRAM on board. For maximum performance, the PCA-6740
also supports one optional SODIMM socket that can accept up to
64 MB memory.
On-board features include an Ethernet interface, a socket for DOC
®
2000, Enhanced IDE interface, one parallel port, two serial ports
(RS-232 and RS-232/422/485) with DB-9 connector as COM1, and a
mini-DIN PS/2 keyboard/mouse interface. An SVGA/LCD display
controller (LCD, and CRT displays) allows LCD screen resolutions
up to 1024 x 768 @ 64K colors and CRT resolutions up to 1280 x
1024 @ 256 colors.
The PCA-6740 complies with the "Green Function" standard and
supports three types of power saving features: Normal, Doze and
Sleep modes.
The display type configuration is done through software. A single
Flash chip holds the system BIOS and the VGA BIOS. This
minimizes the number of chips and eases configuration. You can
change the display BIOS simply by programming the Flash chip.
If you need any additional functions, the PCA-6740 has a PC/104
connector for future upgrades.
