Router Interface
Router Interface
Introduction
The Karrera K-Frame system can interface with an external routing system.
A routing system connects a router source (router input) to a router desti-
nation (router output). Changing the router source sends a different signal
to the destination (called a take). A router destination can in turn be con-
nected to a Karrera K-Frame input and be configured as a routed source
(called switcher source in this discussion and in the GV Switcher menus).
The router acts as a pre-selector for the switcher source, and so increases the
number of inputs available to a button on a Karrera K-Frame system bus
(
Figure 153 ).
Figure 153. Router Source, Router Destination, and Routed Switcher Source
An external routing system can be configured into levels, to allow the
switching of multiple signals simultaneously. For example, video signals
can be organized on one level, and key signals on another. By specifying
both levels when giving a router take command, both the video and key
signals of a source will be routed to their destinations.
Note K-Frame system router Take commands are only applied to all router
levels.The external routing system’s destinations must be configured with all
router levels selected.
Router control panels can also protect router destinations from being
changed by other control panels. A protected router destination cannot be
changed by a different control panel, but may be changed by the panel that
set the protection. Protections help prevent inappropriate router source
changes. The Karrera K-Frame system can be considered a type of router
control panel, and so the system can protect router destinations. The
