1.8 Overview of C960/C990/C990D
1.8.1 What is C960/C990/C990D?
The C960/C990/C990D is an intelligent serial port controller 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 one DB37 connectors to connect external I/O
ports, all the I/O interface control circuitry and connector are built in one
expansion box. There are different boxes for different interface and control
function requirement.
