High Speed Camera Infrared Trigger. Model 33

 

 Phototrap Model 33 Technical Specs Image

This infrared trigger will work in most any lighting condition.  As with any photodetecter

it is best to aim it away from the direct sunlight whenever possible while setting up.

Technical Information

This infrared trigger has three modes of operation;

 
No. 1.... Point-to-point to 20 feet.
No. 2.... Reflective to 25 ft.
No. 3.... Reflective to 42 inches without reflector.
 
Specs for the model 33.
 
No. 1….. Power switch
this Switch turns the power on to the unit.
Push the white dot in for On
 
No. 2… Camera on off switch
Push the white dot in to allow the unit to trigger the camera.
 
No. 3… Camera or Flash ports
Plug the camera cord into either of these ports.
 
No. 4… Trip reset Time
Use this dial to set a Time delay between cameras triggerings

No. 5… Battery charging terminal
AC adapters are available at Radio Shack and other electronic stores
A 1000 Ma 12 volt Charger will charge the battery and about eight hours.
Center post is Positive
 
No. 6… RCA Jack's for sensor leads
Be to sure that these RCA connectors are white to white or
red to red. Do not cross the wire colors as this could damage
the triggering unit
 
No. 7..... Sensitivity dial
Rotating the dial counter clockwise decreases the sensitivity
of the photodetecter. It should be left on # 8 for minimum triggering
time in either mode.
 
No. 8.... Brightness dial

This controls to the power to the emitter. When the separation
of the emitter and detector in the point-to-point and the reflective
mode is less than eight feet the dial can be left
at No. 1 which is the lowest power setting.
After eight feet the power should be turned up to a higher No..
Break the Beam with a dark object once just in from the emitter, and once just in front of the
detector to be sure it is triggering anywhere between the two points.
 
No. 9… Trip light
In the point-to-point mode this light will come on when the beams are not aligned properly
or when the subject breaks the Beam. In this mode(point-to-point) the trip light will be off
when the beams are aligned.
 
In the reflective 42 inch mode this light will only come on when a subject passes across
the two sensors that are together for this mode, or there is not enough clear space in front
of the beam. At least 8 feet is needed.
 
No. 10.... Mode Switch
This Switch changes the operation from point-to-point and reflective
with a reflector to reflective to 42 inches without reflector.
 When the toggle switch is pushed up the unit is in point to point
and reflective with a reflector mode. Pushed down is reflective to 42’’s.
 
In the Point-to-point and Reflective with a Reflector Mode the Trigger Operates in
20 Milliseconds or Less. It is not suitable small objects traveling at higher speeds.
However large objects passing through in a high rate of speed will most likely trigger
the unit due to the longer duration of the time the object passing through the Beam.
An example might be the body of a coyote running fast with the Beam at body center
vs. low on the feet.
In the reflective mode to 42 inches the unit triggers faster.
Experimentation is necessary was all the different species and situations.

No. 11.... Photodetecter

No. 12.... Emitter
Be sure that these RCA connectors are White to White or
Red to Red. Do not cross the wire colors as this could damage
the triggering unit

No. 13…. Battery Indicator
If this lite is on the Battery needs to be charged.
 
No. 14…. Bulb / Meter Switch
If you want to hold the camera in the ‘ BULB’ mode until the beam is broken
connect the Red RCA PLUG from the camera cord into this black jack . This
will keep the camera shutter open in ‘bulb’ even if the unit is turned off.
When the beam is broken, the shutter will close and then open again for the
next frame.
 
Some Canon cameras will not fire more than one time in single shot mode,
unless the meter is fully released. To over come this problem , plug the WHITE
RCA plug from the camera cord into the black jack.(#14). Push the lower switch
(#3) on. This keeps the meter on until the beam is broken, then the meter is
Released and set again for the next frame. If you are shooting multi frames,
you do not need to plug in the white RCA plug. BUT you do need to push in switch
(#2) to keep the meter on. Turn the meter switch off to look at images in camera.
 
ALWAYS shoot with the METER ON as the lag time is the shortest.
 
 

MODEL 33 operating instructions
 
 Point to Point or BEAM-BREAK mode.
 
Mode switch is down.
 
Working distance between detector and emitter; one inch to 20 feet.
The Brightness dial should be turned towards Maximum as the distance between sensors increases. Minimum is between one and two and Maximum is fully clockwise.
 
Separate the emitter and detector for this operation.
 
 Set up the sensors so they face each other. If the detector sees the emitter the LED on the detector will
illuminate. If the detector does not see the emitter, the trip light on the to control panel will illuminate and.
Stay on the until the beams are aligned
 
Sensitivity control. When the sensitivity control dial is turned fully clockwise (8) the cameras will fire immediately upon breaking the beam. When the sensitivity dial is turned
full CCW, the circuit is much less sensitive to breaking the beam. In this case the beam must be
continuously broken for several seconds to fire the cameras. Thus the unit would be responsive to slow
moving targets but not to a target just passing quickly through the beam.
 
 
Reflective to 25 feet or BEAM-REFLECT mode.
 
Mode switch is up.
 
Place the sensors together with the Velcro for this operation.
 
Working distance with the three inch reflector; 3 to 25 feet.
 
Set up the sensors so they face in the same direction. In this mode the cameras will fire if an object passes
between the sensors and the reflector. Aim the sensors at the reflector. They must be on the same plane.
 
The light will illuminate until the beam and reflector are aligned properly.
 
The sensitivity dial in this mode operates same as in the BEAM-BREAK mode.
The Brightness dial should be turned towards Maximum as the distance between sensors and reflector increases. Minimum is between one and two and Maximum is fully clockwise.
 
Reflective to 42 inches without a reflector.
 
Mode switch is down.
 
Place the sensors together with the Velcro for this operation.
 
No reflector is necessarily for this operation.
 
Working distance is 42 inches Max. This Max distance will extend in certain conditions such as, Larger subjects at night. More reflective or white subjects to possibly six to eight to feet.
 
Optimum operating ranges between one foot and three feet.
 
Set up the sensors so they face in the same direction. In this mode the cameras will fire if an object passes
in front of the sensors such that the emitter light is reflected back to the detector.
 
 The trip light LED will illuminate if there is continuous reflection. In a proper setup the trip light LED will be off.
 
 
The subject to be photographed must be within 42 inches of the face of the beams.
Optimum operating ranges between one foot and three feet.
 
 But Most Important, there must be four to five feet of clear space behind the subject
This distance may need to be extended if the background, rocks , trees, branches,
ground or ceiling are highly reflective.
 
 The Sensitivity control in this mode operates the same as in the BEAM-BREAK mode.
 
5. INDICATOR FUNCTIONS. When the unit is first turned on the Trip Lite (On the board) will
illuminate for 1 second then go off.
 
The Trip Lite is programmed with a code to indicate status as shown in the table below.
INDICATOR MEANING
 
OFF Emitter and detector are aligned waiting for a trigger
 
ON (Steady) Emitter and detector not aligned.
 
TRIPLE PULSE The unit has been triggered and is awaiting time-out of the trip delay at which
time the unit will re-arm and be ready to take another picture.
 
Battery Indicator No. 13
 
RAPID REPEATED FLASH
 
The battery voltage has dropped below 9.5volts and the unit is now placed in a Stand by mode
And will not trigger camera or detect subjects.
