RS-485 Control Panels Overview
Introduction
A Router Is Only As Good As Its Control System...
A good control system is reliable, yet flexible enough to allow the switcher to be controlled in a
variety of ways. It will allow the use of a large number of different control panels, intelligent
software GUIs, and third-party automation systems. Sierra Video universal control system gives
you all of that, and more. From simple Push Button control panels to fully programmable panels
customized to your individual installation, SVS offers a panel and software for every application.
Routing switchers like Lassen , Sierra PRO , Tahoe , Shasta , Yosemite , and Sequoia use a
powerful 3-port control system. The physical network structure is RS-485 extended to
accommodate a total of up to 64 panels on a common bus of up to 5,000 feet. The Control
System uses a serial protocol that allows for controlling video and audio levels, AFV, or
breakaway. The panel network software is based on fast polling protocol, the most reliable
software method for networking devices on a common bus. Control panels on the bus can never
take over the bus. Instead, the polling master -- which also is the network interface to the routing
switcher -- is always in control.
The Button per Input control panels come in a variety of configurations. These less complex and
easy-to-use panels simply assign a single button to a single input. Single-Bus buttons are
assignable to one output and any combination of levels; the single operation of pressing a switch
selects the desired input. XY Matrix panels have two groups of switches: First press an OUTPUT
button to enable the desired output, then use the row of IN or SOURCE Buttons to initiate the
switch.
