4.4 Remote Control DMX 512
The Electronic Ballast EB 575 Event Six can be controlled by a remote control
according DMX-512 standard. The remote control connectors are placed on Rear side of
the ballast. Every module has a three-digit switch to select the address of the respective
module in the range from "001" to "511".
Two DMX channels are needed for each module. One channel is used for dimming the
ballast, the second channel is used for switching the ballast on and off. The address of the
first (dimming) channel is selected by the three-digit switch. The address for the second
(switching) channel results of the dimming address incremented by one.
To control the ballast via remote it is necessary that the ON/OFF switch of the module is
in "OFF" position. In this case the dimming potentiometer on front plate of the ballast
has no function!
To switch the ballast 'on' a value between 128 and 255 must be send on the switching
channel. A value of 0 .. 127 will cause the ballast switching off. Dimming is done by
sending a value between 127 and 255 on the dimming channel which will correspond to
lamp power regulated between 50% (127) to 105% (255) of the nominal value.
The green LED "DMX-SIGNAL" at every module shows that DMX signals are received
at the adjusted channel (dimming) and at the next channel (switching). If this LED is
flashing, the selected DMX address is invalid ( < 1 or > 511).
The LEDs "BALLAST ON", "LAMP" and "TEMP" have the same function as described
in "4.2 Operation of 575W Module"
Attention: The potential of the remote control signals at the connectors may not
exceed 70 Volts (peak) against protective earth.
