The Kayak HD production switcher includes up to 6 built-in downstream
keyers. These keying capabilities can be expanded by connecting up to
three external keyers to the Kayak HD mainframe.
The external key module supports all functions which are supported in the
internal keyers and can be controlled from the Kayenne XL control panel.
Since the functions cannot always be transmitted 1:1, certain behaviors
have to be defined. These are keyer specific and are controlled for this
reason by the controller in the mainframe.
