I/O expanders

[andrada08]

We're looking for some basic information on using the input and output expanders. Can you help us with this particular example: we want to send a square wave to the output expander and receive it into the input expander? How do we do this in Bonsai? Also, do we need to connect the behaviour box to the expanders / connect anything to the computer besides the USBs from the expanders?

Can we also output an arbitrary signal from the expander e.g. sine wave? And how can we do this in Bonsai?

Hi Filipe - just bumping this: if you can give us directions on how to setup/use/display the input/output expanders in Bonsai.

Also - why are there labels and lights for 10 ins/outs, but there's only 4 BNC connectors? If we're limited to 4 inputs per box, can we have more than one input expander per setup?

Do you mind splitting your questions into different posts?
It will be easier to explain individual doubts.

Thanks.

Ok - though to be clear: these aren't doubts, we are simply asking for operating instructions since there is no documentation for your hardware.
