Router Interface
The GV K-Frame XP system can interface with an external routing system. A routing system
connects a router source (router input) to a router destination (router output). Changing
the router source sends a different signal to the destination (called a take). A router
destination can in turn be connected to an 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 switcher system bus.

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: Switcher 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 switcher system can be considered a type of
router control panel, and so the system can protect router destinations. The switcher
system router protect commands are applied to all router levels.
Router Source Name Changes (at the Router) and GV Switcher Updates
When an NV9000, Encore, or other supported router is connected to a GV Switcher system
using Grass Valley’s Native Protocol (SMS 7000), and router source names are changed, the
system and menu will now be updated automatically, with a few limitations.
