Spaces
Spaces are logical divisions within a system (such as different rooms) that isolate station
control (preset and sequence control) to the defined group of controllable outputs in that
division. CEM3 supports separation of its controllable circuits into spaces.
Station Functions
Presets can be played back from preset stations in the system.
• Press a preset station button to activate a preset.
• Press it again to deactivate the preset.
• Stations can be configured with an “Off” button. This option is performed at the
station and should only be done by a qualified technician.
• The group of presets controlled by any station can be altered at the station. This
should only be done by a qualified technician.
For more information see the Echo Preset Station Installation Guide available from the ETC
web site.
Zones
A space can be broken down further into zones. You can assign zone control to a preset
station for direct control using that station’s buttons and fader knob. Multiple zones can exist
within a space and a single zone can control multiple outputs across multiple racks.
A circuit’s control zone is a dimmer property and is assigned by accessing the dimmer setup
menu (see “Arch Zone:” in Dimmer Property Definitions, page 19 ).
Each space can have up to 16 zones assigned (numbered 1-16).You can omit a circuit from
zone control by setting the Arch Zone value to zero.
Redundant Tracking (ESR and FDX racks only)
Redundant tracking provides extra security in the event of system failure, allowing a
secondary CEM3 control module to immediately take control of the rack.
Redundant tracking is available in ESR and FDX racks only.
For more information, see Redundant Tracking Systems, page 51 .
