2−87CM 4000 Installation and Operating Manual
Connection to Automation and Other Systems
Note: The following refers to all automation−to−CM 4000 systems, including those with AccuSwitch. The
AccuSwitch application itself is described in Appendix G.
The CM 4000 will support multiple connections to an automation system (e.g., “channel A control” of an automation system
could be connected to Serial Port 1 of the CM and “channel B control” connected to Serial Port 2).
CM 4000s can be installed as a redundant pair where each monitors the other. If a fault is detected in the [active] master unit,
control will be switched to the other device automatically. For more information, see page 2−8.
Connection to Devices Using “ESswitch” Proposed ESbus Routing Switcher Dialect
“ESswitch” protocol is set on the Serial Protocol table (page 5−30); and the control computer is identified on the MPK Devices
table (page 5−107). A technical description of the proposed dialect is available; please contact Grass Valley for more informa-
tion.
