Operation
Control System Overview
The Yosemite Family’s three port control system incorporates many powerful features, while retaining
control compatibility with many leading third party control systems and with most earlier generation SV
routing switchers. The control systems uses an intuitive interface for routing switcher control and
configuration, pass wording, salvo setup, multiple input/output configuration and name configuration.
Windows based, client/server software is IP addressable and supports event timing and bitmap icons. Up
to 64 control panels can be linked at any one time, daisy-chained on a single RS-485 network. A variety
of control panel styles are available including single-bus, X-Y, simple keypad, color LCD multi-bus, and
fully programmable rotary panels.
Connectors associated with the system’s internal control computer are located on the rear of the
Yosemite routing switcher frames. When systems are ordered with more than one frame, only one frame
will have a control computer module installed. The following pertains to the frame that contains the master
control CPU processor, either 505150 or 504001. Additional frames will need to be installed and
connected to the master processor as described in the installation section above.
Note:
The control system and its software may vary slightly between the 504001 and 505150 CPU processor.
Consult Sierra Video if you have questions.
Speed
The 505150 Yosemite control processors have the ability to perform several dozen switches within a
single interval. The circuit used for the Yosemite Family controller is 2 to 4 times faster than the 504001
controller used in the Tahoe / Yosemite Audio Families, while being based on the same micro processor:
the Motorola MC68302.
Serial Control Ports
The internal control CPU processor has three serial ports for Terminal, Host, and RS-485 control panel
protocol. These three serial ports are used for overall routing switcher system personalities, local or
networked PC computer control, and control panel network operation. Terminal Protocol is a human-
readable protocol while Host Protocol is a machine-friendly protocol. The three serial ports are shipped
with a factory default as described below. Altering DIP Switch settings may interrupt the default port
settings.
