Assembly and Operating Instructions for HiViz Kits

 

Connecting a HiViz Trigger Circuit to a Camera or Wireless Transmitter

 

Connection to a camera

 

If your camera has an electronic shutter with a remote cable, you can actuate the shutter using an output of your HiViz trigger circuit. This is a useful thing to be able to do if you're, say, photographing insects, birds, or other unpredictable subjects. You simply can't hold the shutter open waiting for the subject to appear. Another application where it's useful to trigger a camera is in splash photography. The immediate output of a delay unit can be used to trigger the camera and the delayed output to trigger a flash unit. The camera exposure time can be set so that the shutter remains open just long enough for the splash event to be completed.

 

If you wish to connect the trigger to your camera shutter, there are two options.

 

COS option: Build the Camera Opto-Switch. Assembly instructions are here. Then connect the trigger output cable to the breadboard according to the table here.

 

DIY option: Prepare a camera cable according to the instructions here. Then connect the trigger output cable to the breadboard according to the table here (same as for a flash unit).

 

Connection to a wireless transmitter

 

Wireless transmitters such as PocketWizards can be triggered from your HiViz trigger circuit the same as you would trigger a flash unit. Just connect to the transmitter using either a PC cable or Flash-to-PC adapter.
