Figure 2-1. System Connection
CCS-8200 connects the network by 10/100 Base Network Interface
Board (DE-500B) through the switching pab and operate copy server
function. Due to this, each PC on the network can use the common
scanner and printer.
2.1.2 Control Circuit
Hardware architecture of this product is PC/AT personal computer, and
interfaces of ISA and PCI for extension exist respectively.
CPU adopts AMD K6-2 processor, which is driven by 300 MHz Clock,
and has one 32MB RAM-DIMM on the mother board. On the mother
board, CMOS, which records the setting values of BIOS, and a lithium
battery for backing-up are mounted.
2.1.3 ISA Board
On the ISA Board (C85010 I/F), ASIC E02A27, Flash ROM (8Mbit x 12),
EEPROM (AT93C66) and SRAM (256 KB x 1) are mounted. ISA board
is connected to the mother board through ISA bus slot. The figure below
is ISA board block diagram.
