Looking to syncronize camera with Bpod

Nick S

Hi,

I am recording my behavior with an overhead camera while it is controlled by my Bpod setup. For the sake of determining precise location specific datapoints, I want to be able to know precisely in my Bpod data file what time in the video recording certain events are, and I would like to attempt to do this by feeding the camera's activity into the Bpod via a connection like a TTL pulse. However, my initial attempts to do so do not register as a TTL pulse while the camera is on. Any ideas how I might be able to accomplish this synchronization?

Thanks,

Nick

Hi Nick,

Which camera and which Bpod input channels are you using?
The BNC input channels are optically isolated, and some logic outputs can't supply enough current to drive them.
In that case, you can use the 'S' terminal on the port interface board and its neighboring ground terminal.
If you're using a port interface board input channel, make sure it's enabled in the software - from the Bpod console select the wrench icon (settings) and then the port icon.

We are using a Basler Graftek Camera in Pylon. At the time I was attempting to use just the BNC input 1 and 2 channels on the state machine to accomplish this task, but no luck. I can give the port interface board a shot instead to see how that works.
