Chapter 1 1 General Information This chapter gives background information on the PCA-6742 HalfSize CPU Card.
1.1 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 supports ISA interfaces.
Chapter 2 2 Connecting Peripherals This chapter tells how to connect peripherals, switches and indicators to the PCA-6742 board. You can access most of the connectors from the top of the board while it is installed in the chassis. If you have a number of cards installed, or your chassis is very tight, you may need to partially remove the card to make all the connections.

Connectors on the board link it to external devices such as hard drives, a keyboard or expansion bus connectors. The board also has a number of jumpers that allow you to configure your system to suit your application. The table below lists the function of each jumper: Table 2.
2.3 Setting jumpers You may configure your card to match the needs of your application by setting jumpers. A jumper is the simplest kind of electrical switch. It consists of two metal pins and a small metal clip (often protected by a plastic cover) that slides over the pins to connect them. To "close" a jumper, you connect the pins with the clip. To "open” a jumper you remove the clip. Sometimes a jumper will have three pins, labeled 1, 2, and 3.

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. 2.6 IDE Connector (IDE1) 2.7 Compact Flash card Socket (CF1) The board provides a CompactFlash card type I/II socket. The CompactFlash card shares a secondary IDE channel. 2.8 Parallel Port Connector (LPT1) The parallel port is designated as LPT1, and is normally used to connect the CPU card to a printer.
The USB interface complies with USB Specification Rev. 2.0 and Rev. 1.1 under DOS support transmission rate up to 480 Mbps and is fuse-protected. 2.10 Serial Ports (COM1 & COM2 & COM34) The PCA-6742 offers four serial ports, COMD1 as COM1 (RS-232 on real I/O) and COM2 as COM2 (RS-232/RS-422/RS-485 on one 2.54mm pitch wafer box) and COM34 as COM3, COM4 (2*RS-232 on one 2.0mm pitch wafer box). These ports can connect to serial devices, such as a mouse or a printer, or to a communications network.
If fan is used, this connector supports cooling fans of 500 mA (6 W) or less. 2.16 AT power connector (PWR1) If you prefer not to acquire power through the PCA-6742 backplane via the gold Hconnectors, the big 4P power connector (PWR1) also provides power input connectors for +5 V, and +12 V. Provides 14-Pins pin header for Digital I/O usage. Refer to Appendix B for detailed information on the pin assignments and programming guide in Appendix C. The board supports 8-bit GPIO through GPIO connector.
