Chapter 1: Introduction
Introduces main features and specifications.
Chapter 2: Getting Started
Provides abbreviated instructions to get started.
Chapter 3: Connecting the cpuModule
Provides information on connecting the cpuModule to peripherals.
Chapter 4: Configuring the cpuModule
Provides information on configuring hardware and software.
Chapter 5: Using the cpuModule
Provides information needed to develop applications for the cpuModule.
The chapter includes general information on the cpuModule, plus de-
tailed information on storing applications and system functions, and us-
ing utility programs.
Chapter 6: Hardware Reference
Lists jumpers and their locations and mechanical dimensions.
Chapter 7: Troubleshooting
Offers advice on debugging problems with your system.
Chapter 8: Warranty

The CMC6686GX cpuModule
The PC/104 cpuModules described in this manual are designed for industrial applications which re-
quire:
• software and hardware compatibility with the PC/AT world
• high-speed "number-crunching" operation
• low power consumption
• small physical dimensions
• high reliability
• good noise immunity
This cpuModule is highly integrated, combining all major functions of a PC/AT computer on one
compact board. It integrates all primary I/O functions of a AT compatible computer:
• a keyboard interface
• an ECP/EPP parallel port
• two versatile RS232/422/485 serial ports
• a Real Time Clock
• a speaker port
It also enhances standard AT-compatible computer systems by adding:
• one Solid State Disk socket
• a non-volatile configuration without a battery
• a Watchdog Timer
• Fail Safe Boot ROM
The figure below shows a simplified block diagram of the cpuModule:

You can easily customize the cpuModule by stacking PC/104 modules such as video controllers,
modems, LANcontrollers, or analog and digitaldata acquisition modules. StackingPC/104 modules
on the cpuModule avoids expensive installations of backplanes and card cages and preserves the
module's compactness.
RTD Enhanced Award BIOS is also implemented in the cpuModule. This BIOS supports ROM-
DOS, MS-DOS and Windows operating systems. Drivers in the BIOS allow booting from floppy
disk, hard disk, boot block flashor DiskOnChip®, thus enabling the system to be used with tradition-
al disk drives or non-mechanical drives.
The cpuModule and BIOS are also compatible with most real-time operating systems for PC com-
patible computers, although these may require creation of custom drivers to use the SSD and watch-
dog timer.
