The CM-4400 Jupiter Control Module (CM) is designed to control Grass Valley Routing switchers, specific third party routers, and certain other RS-422 devices. The devices to be operated are connected to the CM-4400, which is in turn connected to Jupiter control panels. The CM-4400 is configured using the Jupiter file server. This manual is for the CM-4400, which only supports the Jupiter AccuS-witch control software. For all other systems, including the CM-4000 System Controller, you should refer to that system's manual.
