2−3CM 4000 Installation and Operating Manual
CM 4000 Connection to Distribution Switchers
Although the CM 4000 supports both the JupiterXPress and AccuSwitch applications, 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 Grass Valley Crosspoint Bus routers and the devices on 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 frame. AccuSwitch installation and configuration is described in Appendix G.
