As I have indicated in previous postings, I am using a photodiode attached to the Ergo channel. I was previously getting very good signal when flashing a patch between white and black, with all the three ways I have of viewing its signal: auxiliary sensors tab on ActiView, ActiClient and the C++ Cli...

Thanks for your clarification. Can I just get clarification on one more point? And sorry for asking a very basic question, but I just want to absolutely sure of what I can do with the ERGO signal received through TCP/IP. You write that, “You cannot use the data streamed by TCP/IP for precise timing ...

Thanks - we are following that suggestion.

I am trying to set-up the rail-to-rail test suggested earlier on this thread: “It is always good to check the conversion of 3 bytes to signed 32-bit integers with a rail-to-rail input signal (in your case you can connect a signal generator to the ERGO input). Errors usually show up as large jumps wh...

Thanks - that is now very clear.

Dear Coen, Thanks, that is very helpful. So, just so I am absolutely sure, you are saying that there are 32bits at the sender side, which comprise four bytes (8 bits each), but only the three most significant bytes are sent. The least significant byte is not sent because its value is trivial compare...

I have been coding up an equivalent of the Matlab TCP/IP client on the Biosemi downloads page, but in C++. The example code is very useful and I have got it to the point that I can regenerate the timeseries of a flashing photodiode. This also compares well to what one sees when running ActiClient 9....
