Introduction
1−3CM 4000 Installation and Operating Manual
Section 1 − Introduction
The CM 4000 Jupiter Control System is designed to control Grass Valley Crosspoint Bus* and certain other matrix routers;
video equipment using Sony remote control protocol; and certain other RS−422 devices. The devices to be operated are con-
nected to the CM 4000, which is in turn connected to Jupiter control panels. The CM 4000 is configured using the Jupiter
file server* (Figure 1−1).
Present Jupiter systems may include CM 4000, VM 3000, and/or SI 3000 System Controllers. The VM 3000 and SI 3000
are described in a separate manual.

CM 4000 System Controller

The CM 4000 System Controller provides a hardware platform for the JupiterXPress or AccuSwitch applications. Note that
only one of these applications can be downloaded and executed in a single CM 4000 at one time.
•JupiterXPress provides a limited set of Jupiter switching and machine control functions using the CM 4000 as
the interface between Crosspoint Bus routers and various control devices (as listed in the software package
table, page 1−27). This software cannot be installed on systems containing VM 3000 or SI 3000 processors.
•The AccuSwitch product, when connected to and operated by a suitable automation system, allows determinis-
tic switching of a Crosspoint Bus router, with each switch guaranteed to occur one frame after receipt of the
automation system switch command; and, allows a sustained switching rate of up to 200 physical crosspoint
switches per video frame. AccuSwitch installation and configuration is described in Appendix G.
Note: some Jupiter Control System functions are extra−cost options. See the software package table (page 1−27).
The following overview of system functionality applies generally to a CM 4000 controller running the JupiterXPress applica-
tion. The AccuSwitch application supports a reduced set of functions (as described in the software package table).
An example JupiterXPress system is shown in Figure 1−1.
