1.7 Overview of C888
1.7.1 What is C888?
The C888 is intelligent eight ports serial communication card used for PC
with PCI bus. It includes a local high performance processor to manage the
data flow between main CPU and external interface. It also includes dual
port RAM, through the dual port RAM, the local processor can
communicate with main CPU.
The expansion cable has eight standard DB25 connectors and one DB62
connector to connect to C888 interface card. User may also use one DB62
to DB62 cable to connect between one C888 and C888XB for providing 8
channel isolated RS-232/422/485 interface.
