The CMD6686GX cpuModule The PC/104 cpuModules described in this <strong>manual</strong> are designed for industrial applications which require: • 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 • two USB ports 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 modems, LAN controllers, or analog and digital data acquisition modules. Stacking PC/104 modules on the cpuModule avoids expensive installations of backplanes and card cages and preserves the module's compactness. <strong>RTD</strong> 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 diskSolid State Disk, boot block flash,or DiskOnChip®, thus enabling the system to be used with traditional disk drives or non-mechanical drives. The cpuModule and BIOS are also compatible with most real-time operating systems for PC compatible computers, although these may require creation of custom drivers to use the SSD and watchdog timer. 8
