Overview
The Source Four Dimmer, ES750 and ES1 are universal voltage input, 115V or 230V pulsed DC output,
single dimmers. As a companion to Source Four LED, the Source Four Dimmer, ES750 and ES1 help
to simplify the layout for systems where heavy use of LEDs, moving lights, and other self-dimming
fixtures are planned. They also give additional efficiency benefits for 230V markets. The dimmers
support the ANSI RDM E1.20 protocol (RDM) allowing remote configuration and monitoring of the
dimmer over DMX wiring infrastructure.
Programming
Introduction
At the time of initial power up the software version number will first be displayed. Once the dimmer has
booted, there is the option to either manually set the DMX address or adjust the light output intensity.
Both functions can be performed through the user interface on the dimmer. The dimmer is also capable
of RDM discovery and configuration. RDM functions include reporting status feedback, selecting the
output curve and setting the DMX start address.
Setting DMX address
The DMX address will appear on the user interface display on two occasions:
• At time of initial power up
• After initial power up if the display is blank and either the plus or minus button has been pressed.
To change the DMX address, push the plus or minus arrow button. The DMX address will increase or
decrease with acceleration based on length of time held down. This can also be done through the RDM
interface.
Note:
DMX is not self-terminating.
