Your cable: Cat5E or Cat6? And whats the distance? Cat5E is the minimum at Gigabit and not all Cat5 cable is up to par. Cheap stuff bad. Never let your boss pick it. Must make sure no sharp bends and cables that are made in house maintain the twists all the way to termination, A fellow here made the cables without my help.... he untangled the twists about one inch+ back. I had to redo them all.</p> <p>Your cable could be increasing the error rate just enough. </p> http://www.winextra.com/forums/topic/10776#post-54027 Wed, 01 Feb 2012 23:55:35 +0000 ChadMan 54027@http://www.winextra.com/forums/ <p>Lady faulty.

She should try putting magnet shields on the ends of the video cable and see what happens. </p> http://www.winextra.com/forums/topic/10780#post-53976 Fri, 27 Jan 2012 16:42:15 +0000 Nate 53976@http://www.winextra.com/forums/ <p>I have two high tech cameras connected to a Gigabit LAN (a Gigabit switch and my computer) that send data at at rates between 1 and 2 seconds per image per camera.</p> <p>When i run my app with the system monitor on and (nothing else that I can turn off running) the monitor shows a bit over 25 MB/s which is about what it should be at 1.65 seconds per image. But I usually get some lost packets and then 1 lost frame.</p> <p>The bandwidth used is probably between 200 and 250 Mb/s on this 1,000 Gb/s system and I'm using a MTU of 8228, lower than the maximum for the NIC or the switch. </p> <p>Is this kind of low for the real world? &lt;img src=&quot;http://www.winextra.com/forums/my-plugins/smiley-choice/Default Smiley/icon_confused.gif&quot; title=&quot;:?&quot; class=&quot;bb_smilies&quot; /&gt; </p> <p>More info:</p> <p>On my end I use some code and a type of buffer defined in the vendors' SDK. I can set from 2 to n buffers (frames) per camera (each camera acquisition code is in it's own thread). I don't see a difference going from 4 to 6 frames. I have some debugging timers set up and see that each thread waits an average of 900 ms for the next available frame after having moved the raw data to disk so I don't think it's my code as it's simple.</p> <p>I need to find a base level so that I can transmit about 40 minutes of images without frame errors and at that point will attempt see how long it takes to process the data on it's way to the disk so that I can estimate real world throughput and see if it is reasonable for our work.</p> <p>This is on Ubuntu Linux and I'm using Eclipse for and IDE but am not running in debug mode. There's another LAN connected to the internet and I run with everything turned off that I can. In the end it will run without XWindows and as root so there should be a little speed increase. </p> http://www.winextra.com/forums/topic/10776#post-53975 Fri, 27 Jan 2012 14:26:08 +0000 Callow 53975@http://www.winextra.com/forums/ <p>Soooooo.......she brought the monitor, plugged it in to her PC and it works fine.
