2. Local wired pendant control -- a hand held pendant can be attached via a 3 pin
XLR cable to manually open and close the fins. Movement from fully open to
fully closed or visa versa takes 5 seconds - this allows precise fin positioning.
Press the "+" button to open the fins and the "-" button to close them. Either the
pendant buttons or the buttons on the dowser itself can be used in this mode.
The wired pendant cable can be up to 1000 feet long.
3. Local push button control -- the dowser unit has two momentary push button
switches to manually open and close the fins. Movement from fully open to fully
closed or visa versa takes 5 seconds - this allows precise fin positioning.
Press the "+" button to open the fins and the "-" button to close them. Either the
pendant buttons or the buttons on the dowser itself can be used in this mode.
Signal and Power
The Eclipse II Dowser uses a Coloram II Power Supply and Coloram II cable for
control signal and 24VDC power. The dowser can be daisy chained with Coloram II
Color Changers and Goboram IIs. Fin position is determined by the DMX level (0-
100%) of the DMX channel to which the dowser is addressed. The dowser uses one
DMX channel.
Coloram II Cable
Connect the Eclipse Dowsers to the Coloram II Power Supply using the 4-pin
Coloram II power/signal cable.
There is a limit to the number of dowsers/color changers and total cable lengths used
on one "home run". This is measured in "head-feet".
The definition of head-feet is THE SUM OF THE CABLE LENGTHS FROM EACH
DOWSER OR COLOR CHANGER TO A SINGLE POWER SUPPLY OUTPUT
CONNECTOR. See the Coloram II User Manual for a complete explanation of "head-
feet".
The head-feet limit for the 1K and 2K Eclipse II Dowsers is 1000 head-feet. For the
24-inch model, it is 750 head-feet.
If a daisy chain consists of different models, use the model with the least amount of
"head feet" for the calculation. See the Coloram II User Manual for head-feet figures of
other Coloram II products.
Fan Speed Control
The fan in the Eclipse II Dowser is small and cools electronics enclosure. Therefore,
it always runs at full speed and CANNOT be slowed or stopped.
