Pro-Dowser, DMX Projector Dowsing System
Features
? Allows DMX512 protocol control of flag-type lens shutter.
? 30 millisecond close time through 45 degrees of travel.
? Mini DIP address switches for full 512 channel access.
? AC power adapter.
? 5 pin Male and Female DMX signal connectors for daisy chain through
connection.
? Optional Add-On units for multiple projectors on adjacent channels.
? Optional DMX Termination switch onboard device.
SPECS
Input Signal
The Pro-Dowser accepts DMX512 input as specified by USITT. The unit is
programmable to all 512 channels. If optional Add-On dowsers are used
they must be assigned as the first three adjacent addresses after the start
address as set by the DIP switch.
Shutter Flag Range and Motion
Default range is approximately 90 Degrees with DMX 00 = zero degrees and
DMX FF = 90 degrees. Shutter speed and arc of travel are adjustable within
the 90 degrees by means of the DMX value and fade time sent.
LED Indicator
The LED indicator located to the side of the DMX address window provides
information regarding unit power and DMX signal as follows:
No Light = No power to the unit
Slow Flashing Light = Power Good but Dirty or No DMX Signal to Unit
Steady Light = Good Power and Good DMX Signal to Unit
Address switch
9 position mini DIP switch. The addressing scheme is binary total + 1.
Refer to the addressing chart later in this document for more information.
Power requirements
110v AC, .3 Amps, 60 Hz. with “wall wart” Power Supply. May be
powered remotely from 9v batteries.

Description
Physical Dimensions and Layout:
The durable ABS plastic case of the Pro-Dowser measures 3” x 6” x 2”. The
flat black aluminum dowsing flag is 5-3/4” long x 2-3/4” wide.
Connections:
Connection to the DMX network is via five pin XLR connectors located
on the side opposite the flag motor drive. DMX “in” is the male connector.
DMX “Pass Through” is via the female Connector. The power connection
for the unit is located on the side opposite the flag motor drive and between the
Address Window and DMX Connectors. The power requirements for the
unit are 9 volts, DC at no less than .30 amps.
If the Shutter Flag does not have a clear path of travel or hangs up on other
hardware in the rig Serious Damage can occur to the voltage regulator,
motor driver or other circuitry. Please be sure that you do not damage
your dowser. Check for a clear path of travel for the Flag.
The use of the optional termination switch is very straight forward. If you
wish to terminate a run with this device the switch should be in the “I”
position. At all other times it should be in the “O” position. Be aware of
your setup and do not “Over Terminate”.

Using the ProDowser
When your ProDowser is shipped it is configured for top mounting as shown
on the cover page of this document. When the DMX signal is at 00 (0%) the
dowser flag will be in the down position, blocking the lens of the projector.
When the DMX signal is at FF (100%) the flag will be up at about 90
degrees and out of the way of the lens.
Unless you want the flag to travel at less than it maximum speed of .40
seconds or less than the full travel of about 90 degrees, you may want to set
the profile of the channel you use to “Full at 1%”. This will make the flag
move to the open position at the beginning of long cues.
Recommended set up for this basic installation is as follows:
Before set up: Be certain that the installation of the dowser will not
block access to projector controls or ventilation!
Stick the adhesive hook tape to the bottom of the dowser case. Apply the
loop tape to the hook but do not expose the adhesive yet. Apply a DMX
signal of 00 to the dowser (the Flag should be pointing down from the drive
servo) and position the flag such that it is as close to the front of the lens as
possible and fully blocks the lens of the projector. Now, expose the
adhesive of the loop tape and stick it down to the top of the projector.
Operate the flag by running the dimmer from 00 to FF a few times to ensure
that the flag has a clear path of travel and fully blocks the lens when in
the closed position. A ratchet strap, zip tie, gaff tape or other mechanical
fastening system may be used in addition to the hook and loop tape.
The set up above may be altered to mount you dowser on the bottom of a top
mounted projector, however, a ratchet strap MUST be used to secure the
dowser unit.
In the event that you need to mount the dowser in front of the projector or
off to the side, the flag can be adjusted to other angles on the drive servo.
The black #0 Phillips keeper screw visible through the flag is removed and
the flag assembly gently slid off of the splined drive shaft. Reposition the
flag on the drive shaft as appropriate to your application and re install the
keeper screw. Operate the flag by running the dimmer from 00 to FF a few
times to ensure that the flag has a clear path of travel and fully blocks the
lens when in the closed position. Adjust the position as needed and secure
the dowser as mentioned above.

Troubleshooting
The Pro-Dowser unit is essentially plug and play. When all connections are
properly made, addresses set and DMX signal present the shutter flag moves
through 90 degrees of arc proportional to the input signal from the
controller.
Signal Ground/common
In the unit there is NO connection between chassis ground and signal
ground. Do not make one. On the DMX data cable, there is NO connection
between the shield/XLR shell ground and the signal ground. Do not connect
these together.
Termination
The Pro-Dowser does not contain a terminating resistor. It is up to the user
to determine the termination requirements. If the unit is the last on the DMX
network a terminating resistor can be installed on the open DMX connector,
across pins 2 – 3.
Your Pro-Dowser can be ordered with on board termination switch option.
No Flag Movement
Check the DMX wires for signal. Be sure the DIP switch is set to a valid
address. The unit’s address should not be higher than the highest address
received. The mini DIP switch is marked on and off.
Erratic output
This problem can be hard to track down.
First check the input signal integrity. Your Power/Signal LED should have
a steady glow. If it is Blinking at about one second intervals you have no
DMX signal at the Unit. Try another DMX instrument on the line. If the
problem is in the cable check that the data line polarity is correct.
Drive Motor Chatter
Check the cue that is operating the dowser. The slower the fade time the
slower the flag moves. The slower the flag moves the less smooth it will
be. A weak or damaged power supply can also cause the shutter flag to
chatter through the arc or at the ends of its travel.
Misc
Good solid connections are a must. DMX512 signal wires should be twisted
pairs all the way to the connector. It is recommended that you use only the
power supply that shipped with your Pro-Dowser. Occasionally unexpected
problems can occur if power is ”borrowed” from another source.
