EDMX
Though the Patch display indicates that you are patching dimmers to channels, what you
are actually doing is patching an EDMX address to your control channel. EDMX is ETC’s
proprietary protocol for transmitting DMX information over an Ethernet network. The suite
of ETC network protocols is called ETCNet2 and is the communication method used by the
Emphasis Server and the Facepanel. ETCNet2 is also used in systems that contain Video
Nodes and DMX Nodes. The Video Node allows you to see the Facepanel display(s) and
attach a Remote Focus Unit, an optional keyboard and Remote Macro controller at a
location away from your Facepanel. The DMX Node can be configured for up to four DMX
outputs or inputs, and allows you to have DMX outputs and inputs away from your
Facepanel.
There are 32,767 addresses available in EDMX, which corresponds to 64 universes of
DMX. DMX is the industry-standard protocol for controlling dimmers from a lighting control
console. Each universe of DMX contains 512 addresses. Each Emphasis Control System
can be custom-configured to the needs of the venue, so to explain how patching to EDMX
addresses gets you industry-standard DMX at an output in a simple system, please see the
diagram below.
Using Emphasis with Dimmer Doubling™
Dimmer Doubling is a feature of ETC Sensor dimming that enables you to use a single
dimmer and a special two-fer to control two Source Four fixtures separately, In Emphasis,
there is no convention for patching dimmers as 1A and 1B to indicate which side of the
Dimmer Doubler you are using, as was the case in previous control consoles. To patch
doubled circuits, you will need to patch the EDMX address corresponding to DMX 1-256 for
the A-side of the doublers and EDMX addresses corresponding to DMX 257-512 for the B-
side of the doublers.
If you have any questions about patching Dimmer Doubling within an Emphasis Control
System, please call ETC Technical Services (see Help from ETC Technical Services, page
3 ).
N o t e :
Dimmer Doubling is available only for ETC dimming systems operating at a nominal 115
volts, 60Hz. It is not available for systems operating at other voltages or frequencies.
