Shutter-Beam Specs

The Shutter-Beam is packed full of features that make it easy to use and  flexible enough to fit into any photographic situation.

Very Important Features:

Output 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 pictures.

Output Pulse Duration:

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.

Beam Align Circuit:

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.

Visual Aids:

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.

External Power:

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.

KBO:

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.

Make/Break:

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.

Steady/Pulsed:

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 Beam undetected.

TTL Output:

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.

Low Battery LED:

A Low Battery LED turns on when the internal batteries are low and in need of replacement.
