Here's some useful info:
Using CyberSync to actuate the shutter of your camera, second camera or remote camera:
Both the CSR and CSRB receivers are capable of remotely tripping a camera shutter from the CST transmitter test button. You will need an auxiliary remote shutter cable for your particular camera. Flash Zebra carries inexpensive cables for this purpose for many popular cameras at this link: http://www.flashzebra.com/shutter_pw/index.shtml
These cables typically force the camera into continuous focus mode (or you can use manual focus). This is because the camera must be ready to trip when it receives the short fire pulse from the CSR or CSRB receiver.
A major consideration when using CyberSync to trip a camera is the fact that the camera has a few milliseconds of delay between the instant it receives a trip command and the time the mirror flips up and the shutter is opened. Because of this delay, you cannot use the same CST signal that trips the camera to fire your flash units. The flash units would fire before the shutter is open and you will have no exposure. But there is an easy remedy:
Set the CST transmitter that will trip the camera on a certain frequency (call it Frequency A). Use the same frequency on the CSR or CSRB that will trip the camera via remote cable.
Place a second CST on the hotshoe of your camera and set it to a different frequency (Call it Frequency B). Use Frequency B on the CSR or CSRB receiver(s) that are connected to your light(s).
When you press the test button on CST A it will trip the camera. As soon as the camera responds and opens its shutter it will send a trigger signal from CST B on its hotshoe. This will fire the lights on Frequency B in sync with the camera shutter.
Using a local camera, a remote camera and two sets of lights:
Consider the situation where you want to use a local camera in conjunction with a remote camera to take pictures from two angles, with different lighting effects.
Place a CST (Frequency A) on the hotshoe of your local camera. Put CSR or CSRB receiver(s) on Frequency A on the light(s) you wish to use in your local camera shots. This will fire them normally and in sync with the local camera.
Connect the auxiliary shutter release cable of the remote camera to a CSR or CSRB also set to Frequency A. This will trip the remote camera a few milliseconds after your local camera.
Place a second CST on the hotshoe of the remote camera, set to Frequency B. Place additional CSR or CSRB(s) set to Frequency B on the light(s) you wish to use to expose the remote camera. They will now fire in sync with the remote camera. Any flash-sensitive slaves must be disabled for this to work.
It may be possible to trip two or more cameras from a CST using a single set of lights:
But because of shutter response time differences it will probably be necessary to use identical cameras and it may be necessary to use a slower-than-normal exposure time setting on the cameras (perhaps 1/30 to 1/60 second). To attempt this:
Use a CST set to Frequency A as a trigger for all cameras. Connect a CSR or CSRB set on Frequency A to each camera via auxiliary shutter release cables.
Place a CSR set to Frequency B on one of the cameras and place CSR or CSRB receiver(s) on the common flash unit(s).
CST A will trip all cameras when you press the test button. The camera whose hotshoe contains CST B will send a flash command to the common flash unit(s) when its shutter is opened. This will only work if the cameras all have very close to the same shutter delay, and will require some experimentation with which camera contains CST B and with exposure times.
Using CyberSync with battery operated “Speed lights”:
Both the CSR and CSRB should fire virtually all such flash units if the proper connections are made.
Some such flash units employ a female “PC” style sync input. If this is the case, you would simply connect the auxiliary 3.5mm mini-phone male to camera-style “PC” male (included with CSRB) from the CSR or CSRB PC sync input.
If the Speed light has only a hotshoe connection and no sync cord input, you will need an auxiliary “hotshoe to 3.5mm male mini-phone “ adapter. (These are available from Flash Zebra at http://www.flashzebra.com/wizardcables/index.shtml and other sources.) Place your speed light on the hotshoe adapter and plug the 3.5mm plug into the CSR or CSRB.
Using CSR or CSRB with flash units using two-prong household style sync inputs:
This will require an auxiliary male 3.5mm mini-phone to “H” connector cable. These are available at http://www.flashzebra.com/wizardcables/index.shtml and other sources.
