Setting the port to Dimmer Doubling
If your console is controlling an ETC Sensor dimming system that can
operate in Dimmer Doubling mode, each dimmer and the port to which
the dimmer is connected must be individually set to support that feature.
Moving light fixtures cannot be patched to a doubled port.
WARNING: Set the port mode using the procedure below BEFORE you
create your patch. Changing a port to or from Dimmer Doubler mode
unpatches all conventional lights and moving light fixtures controlled by
that port.
Use the following procedure to set a port’s mode to double. Use the
procedure given under Setting dimmers to Dimmer Doubling, page 53, to
set the mode of individual dimmers to double.
1. Press [Setup] to display the Setup Menu.
2. Press [2], Output Configuration, and press [Enter].
3. Press [S1], DMX512 Port, enter the port to configure (port 1, 2 or 3).
You may also use [↓] to select a port.
4. Press [Enter].
5. Press [1] to set the port for Dimmer Double mode or [0] to set the port
for Normal mode.
6. Press [Enter] twice to confirm your choice.
7. Display identifies mode as either Normal or Double.
Setting DMX512 speed
If your console is controlling a dimming system that requires a slower
DMX512 signal, specify this in the Output Configuration screen
The console is designed to run at the highest rate provided for in DMX512
specifications. Some dimming systems (including some Colortran ENR
dimmers) may require a signal slower than the full DMX512 specification.
If this proves necessary, you may reset the console’s signal speed.
Speed choices are Slow, Medium, Fast, and Max. When installed, the
console defaults to Max. If you have problems with outputs flashing,
fades not running smoothly, or unselected dimmers rising spontaneously,
experiment with slower speeds until the symptoms disappear. If the
symptoms persist, please call ETC Technical Services at 800-775-4382.
To reset the DMX512 signal speed, follow these steps:
1. Press [Setup] to display the Setup Menu.
2. Select 2, Output Configuration, and press [Enter].
3. Press [S4], DMX512 Speed.
4. Press [0] for Max, [1] for Fast, [2] for Medium, or [3] for Slow. The
speed you choose appears in the upper right corner of the display.
5. Press [Enter] to confirm your choice. The display shows the speed
setting.
