Re: External Sync In

<t>VilMax = 0.8V<br/> VihMin = 2.5V<br/> VihMax = 13V<br/> Max Freq = 10kHz<br/> <br/> What I meant was, can you explain in simple terms the requirements to get the hub to respond to the signal that is sent to it? We think we have met the requirements but the hub is 1)altering our signal and 2)not c...

Re: External Sync In

Are there any more details about this? Could you define the specs form the OptiHub manual in a little more simple terms?

Re: External Sync In

<t>The signal in the picture is what we are sending via a DAQ board to the hub. Like I said, when the BNC is disconnected from the hub it shows a steady 5v, as it should, but the signal you see is what happens when we plug the BNC into the External Sync In port on the hub. Something is causing the s...

Re: External Sync In

http://i.imgur.com/mFKnN.jpg These are my settings. We have tried this with veriosn 1.8.1 and 1.7.3 with no luck. Also, the sync dialog in 1.7.3 does not tell which hub serial number to use. Are there any details about what the signal is supposed to look like? We cannot decipher things too well fro...

External Sync In

<t>Hello,<br/> <br/> We are trying to trigger recording in Arena with an external analog rising-edge signal sent from a DAQ board. We are currently using a 5v signal but we can modify this as needed. We have plugged the BNC into the External Sync In port on the proper OptiHub, and have verified that...

Re: Stream Arena to Matlab using NatNetML.dll

<t>I've tried various methods to implement the listener:<br/> <br/> h = NatNetML.FrameReadyEventHandler(@greenbeans);<br/> h1 = m_NatNet.addlistener('OnFrameReady',@greenbeans);<br/> h2 = h.addlistener('OnFrameReady',@greenbeans);<br/> <br/> I don't get errors but I'm not sure how to make sure it is...

Stream Arena to Matlab using NatNetML.dll

Hello, I am trying to convert the WinFormsSample code to Matlab to be able to use the functions in the libraries. I am not quite sure of the order of steps to take, and also how to access the data in Matlab. I don't have much experience with object-oriented programming, so even the NatNet User's Gui...
