Patch
Patching governs the relationship between control input sources (DMX A, DMX B, and
sACN) and the control of circuits in the rack. This relationship can be edited to match the
needs of your control sources and rack constraints. For information on patching, see
.
Preset Functions
CEM3 supports a built-in preset control system allowing the recording and playback of
preset looks. Preset looks can be played back either from the CEM3 face panel or using
connected Echo preset stations. For more information on recording and playing back
Recording and Playing Back Presets, page 32
CEM3 allows the circuits within the rack to be divided up into spaces (performed in
) with 64 presets available per space. Each space can only have one
active preset at a time.
CEM3 includes default presets that include all circuits in the space. The default presets for
any space start with 100% and then cycle through 75%, 50%, 25%, 100% and so on.
Sensor3’s built-in EchoConnect power supply is limited to powering six racks or panels and
six stations. An additional wall mounted or rack mounted power supply can be added to a
system to support up to sixteen hosts and sixteen stations
Preset activation propagates across the Net3 network. So if a given preset is activated for
Space 1, all CEM3s on the network will activate that preset for space 1.
Rig Check
In Sensor3 racks with Advanced Features (see
Advanced Features (AF), page 10
) you can
record a special preset called “Rig Check” which includes both circuit levels and the amount
of load (current) expected on each circuit.
Once recorded, the rig check can be played back, either from the CEM3 face panel or
remotely, and the CEM3 will post load high, load low, or no load messages based on how
the load of the circuit has changed since you recorded the rig check preset. These
messages will be available on the CEM3 display or on a connected console that monitors
AF feedback.
Recording, running, and clearing a rig check can be performed from the Test menu (
)
C A U T I O N :
Do not activate “Station power” on more than one CEM3 on the same
EchoConnect bus. Doing so may cause undesirable station function.
