The System Control
Unit
The SCU processes the flow of data between the member voting
stations and the Operator’s computer and Session Software. It communicates with
the desk stations either via a home-run style wiring system in which the SCU is
directly connected to every desk station or via a Controller Area Network with
a processor at each member location.
|
The SCU is made up of IRC-produced circuit cards and PC
board devices, which enable it to process the data and interact with the
software modules. Typically the SCU is designed to mount in an equipment rack
of a size within the customer’s requirements along with other computers and
electronics related to the voting system, all accessible through a built-in,
extendable KVM keyboard, mouse, and monitor drawer.
