External Interfaces
Introduction
The Karrera Video Production Center has that name because it is more than
just a video switcher. For example, a Karrera system is also able to control
a variety of external devices.
Devices can be associated with Karrera sources, via source definition. Three
types of Karrera source definitions are available:
• Direct (used for standard video and key inputs, not for external inter-
faces, as explained in Direct Source Definition on page 113 ),
• Device (used for DDR and VTRs). These devices can be controlled via
Ethernet or serial port using various protocols. Each device uses a
Device Definition that specifies the control mechanism.
• Router (used with an external routing system). This type permits the
assignment of an external routing system destination to that Karrera
source. Once assigned, different external routing system sources can be
routed to that destination with the Karrera system. It is also possible to
associate a router source to a device, to allow machine control of that
source whenever it is selected on the Karrera Control Panel.
Karrera serial ports can also be used to control PBus configured external
devices.
GPI outputs can be configured to provide relay closure control of hard-
wired external devices from the Karrera system.
In addition, external control of a Karrera system is possible using GPI input
connections, and by configuring an Editor with a Karrera serial port.
