Hello,

I have observed in the most recent group order that about two-fold more imaging sensor PCBs have been ordered than DAQ boards. I saw a similar trend in the previous group order. Unless, I am missing something. I believe the DAQ board can only take one CMOS sensor since it lacks a dual serializer-deserializer set-up. The behavior camera which the software recognizes is actually a secondary UVC compliant USB camera which connects directly to the computer.

Thus, I am not sure if I am wrong, but maybe it should be listed somewhere so that people would not buy extra CMOS sensors unless they really need to. Unless, there is a reson for having more sensors which I am missing.

feel free to let me know if I am wrong :).

regards,

Hi Walter,

You are correct that the DAQ PCB only supports one scope at a time but there are a few big advantages to having mutliple scopes per DAQ PCB. Generally we suggest for each researcher to have his or her own DAQ PCB along with 2 to 8 scopes. The reason for this is we think it is best to lock the focal depth in place for a given animal/scope once and not change it for the entirety of the experiment. If this is done, every time the researcher attaches the scope to the animal he is imaging the same depth (same cells). Depending on how many implanted animals you have concurrently will define the number of scopes you will need.

That being said, one could use the same scope and change the focal plane each time it is switched between animals.

What we like to do is have around 5 to 8 scopes all set at different imaging depths for each researcher. With this setup there will likely be one scope that is already set to the correct depth for each animal meaning 5 to 8 scopes can cover all implanted animals.
