Thanks for the idea brad, I’ll check that out right now.
Lou,
The OS I’m using is Ubuntu 14.04 LTS and I am getting the signal on the
received side when I use UDP. It’s just my biggest concern is why is my
data still dropping even though it’s independent of the sample rate
rising or lowering?
I’m currently experimenting with TCP to see if I wouldn’t drop data, but
am dealing with a socket connection error.

Alan,
I also agree with that, which is why I think it’s probably the reason
why I might be losing packets.
Right now, I’m experimenting with TCP since during my readings I’ve read
that it ensures delivery of all packets and also checks for errors. The
current problem with TCP is that I’m getting a socket error:
(socket.error:[Errno 111] connection refused) no matter how many ports I
open or change it to.

It is my understanding that the UDP protocol does not quarentee delivery
to the destination. That is, it has no recovery mechanism for
undelivered packets.

I’m talking about the UDP traffic between the host and the N2xx device.

Marcus,
What OS are you using? I had the same issue (UDP not getting through on
receive side) with Fedora 20, even with Firewall “supposedly” turned off
(i.e. Trusted Zone selected). Manually adding the port exemption (I
believe
I used port 65000) let the UDP through and it worked.

I don’t think it’s a firewall rule problem, but do you think opening up
ports would solve my problem? I know the port I’m currently using on the
TCP connection is port#: 1234 which deals with Mercurial and git default
ports for serving Hyper Text.When I had the UDP connection, I was using the same port (1234) except
that in UDP, that port deals with a VLC media player.

Make sure on the server you’re binding to 0.0.0.0 (use netstat -na to
confirm).
TCP may help over UDP unless the dropped packets
were caused by congestion, which seems like a likely culprit.
