Introduction
The PCM-4822 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, taking no more space than a
3 1/2" hard drive. An integrated 16-bit Ethernet interface and
4-channel TTL level compatible digital I/O makes the PCM-4822 a
complete processing system. High-performance 486 processors
from 486DX up to 486DX4-120 CPUs and 5x86 CPUs are supported.
For maximum performance, the PCM-4822 also supports an EDO/
Normal DRAM SIMM socket that can take up to 32MB memory.
On-board features include support for VL-Bus Enhanced IDE
interface with up to Mode 3 transfer protocol, two serial ports (RS-
232 and RS-232/422/485) with DB-9 connector as COM1, a mini-DIN
PS/2 keyboard/mouse interface.
The PCM-4822 complies with the "Green Function" standard and
supports five types of power saving features: Normal, Conserve,
Doze, Sleep, and Suspend modes.
If you need any additional functions, the PCM-4822 has an on-
board expansion bus connector for future upgrades.
