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
