Figure 3-2: XL Control Head
The XL Control Head is a networked device that uses a wired Ethernet connection to provide remote control
of the VCH. It includes a color LCD graphical user interface and physical knobs and buttons to allow a user
to control the radio or view its status. The control head also provides multiple audio interfaces to capture
and play real-time audio.
The XL Control Head’s mission-critical design provides a tactile interface optimized so that users can keep
their eyes on the road and still operate the radio. Controls and display are laid out to give instant access to
primary use cases.
