we are currently in the process of designing a measuring device with a AlliedVision Manta G-223B BL-FC200-MCS.
We now have the question of triggering multiple cameras (2 - 4) simultaneously.
I have found this comparison by AlliedVision: Trigger over Ethernet versus other trigger modes
I can see how to use the other trigger modes with the CVB C++ SDK.
However I cannot find any way to send the Action Command as a broadcast. I have also not found anything about action commands in the C++ Programming Guide installed with the SDK.
How do I send the Action Command as a broadcast to all cameras at once with the CVB C++ SDK?
There is also the option of using a hardware trigger that
either triggers all cameras by using an external triggers source that then connects to the IO of all cameras or
by using one of the cameras as the primary camera, that runs in free run mode, that is than connected to the secondary cameras via IO. These secondary cameras are then triggered by the strobe out of the primary camera.
If using option 2:
Triggering 3 or 4 cameras from a single output would exceed its maximum current rating, right?.
That means I would need some kind of relay? Probably solid state for speed?
Hi, according to the user manual one output can only drive up to 10mA.
e.g.: Out1
Each input will draw 4mA approximately.
The camera is providing the two outputs Out1 and Out2. Each output could drive two camera inputs in parallel.
When only one output can be used I would recommend a so called Timing Controller which is outputting a copy of the input signal. The controller is providing eight inputs and eight outputs, each capable to drive up to 50mA.
Please refer to our homepage for a datasheet for the Timing Controller called CC320. For example the wiring of a single AV MANTA with the CC320. More cameras can be added in the same way.
