IQCSPI Serial Port Interface
Module Description
The IQCSPI is a serial port interface for external
devices and all RollCall compatible products.
The SPI card consists of 4 serial interfaces, 3 x
RS442, and 1 x RS232/RS422.
The IQCSPI can control many types of devices that
have serial ports, including tape machines, routers
and disk stores.
In addition the IQCSPI may receive commands
from an intelligent control panel with a serial port,
thus producing a quick customised user interface.

Each button could activate pre-defined commands
such as router switching (e.g. IQDMX8) or frame
freezing (e.g. IQDMSDA).
one input can be generated, producing many pre-
defined commands via RollTrack.
The IQCSPI can communicate with other IQCSPI
and GPI (General Purpose Interface) products.
Thus pre-defined commands can be generated
from external devices to other external devices via
the RollCall network.
A set-up program is provided for downloading
configuration information to the IQCSPI card
