Lockout: (My Favorite)
The Output Lockout feature suppresses
outputs when a subject continuously trips the Shutter-Beam.
Providing a time out period when pictures will not be taken. The
Output Lockout is continuously variable from .2 seconds to One Shot
mode (only one picture will be taken until the unit is reset). This
time can be used to allow strobes to recycle, or eliminate unwanted
The Output Pulse Duration dip switches set
the length of time the Shutter-Beam holds down the camera shutter
via the camera output. The Output Pulse can be set to 14 distinct
durations of 1/1000, 1/500, 1/250, 1/125, 1/60, 1/30, 1/15, 1/8,
1/4, 1/2, 1, 2.1, 4.2, 8.4 seconds. When used with a camera motor
drive, this feature allows for multiple shots of an event.
The Beam Align Circuit simplifies the beam
alignment procedure by emitting a beeping tone that slows down in
frequency as beam alignment is optimized. This makes beam alignment
easy. Proper beam alignment saves battery power.
A group of three LEDs give vital visual
information about the status of the Output Pulse Duration, Output
Lockout, and Beam Alignment ant the trip levels of the Shutter-Beam.
They are visible from both the front and back of the Shutter-Beam.
A 2.1 mm power jack is provided so that any
12 to 28 Vdc power source can power the Shutter-Beam externally
overriding the internal batteries. The optional wall transformer is
plugged into this jack, and with a car battery the Shutter-Beam will
last for months in the field.
The KBO (Kill Beam on Output) switch turns
off the IR beam during a camera output. This feature is a necessity
when IR sensitive film is being used.
The IR Beam can be set up such that
ANYTHING entering (BREAK) the beam triggers an output, or conversely
anything leaving (MAKE) the beam can trigger an output.
Normal operation of the IR Beam is in the
pulsed mode where the IR Beam is modulated (Pulsed On and Off) at 10
Khz. A STEADY Mode (Always On) is provided for extremely fast small
moving objects (ballistics),so that nothing can pass through the IR
The camera output is equivalent to a 1 amp
relay and can control any device (Video Cameras, Video Computer
Boards, Lasers, Alarms etc.) that is started by a contact closure.
This output is TTL compatible.
A Low Battery LED turns on when the
internal batteries are low and in need of replacement.
