Constrain CompactRIO Ethernet Port to 10 Mbps

[BrandonGT]

Hello all,

I apologize if I am not posting in the correction section, but this seemed like the best spot for it. I am currently controlling a CompactRIO 9014 with a 4 slot 9113 chassis. I am having intermittent issues with communications that I have been told are likely related to the Ethernet connection speed. I am trying to constrain the link speed to 10 Mbps without using a hub or additional device. I have found the setting in my network card on my computer to reduce the connection to 10 Mbps, but I cannot figure out if it is possible to do it on the RIO. I found a place where this setting can be changed from AutoNegotiate to various link speeds, but all the other options are grayed out. Is this something that I can do or must I get another device to do it outside of the RIO. When I change only my laptop network card to 10Mbps it connects and disconnects repeatedly without making a consistent connection (I assume this is from the RIO attempting to go up to 100 Mbps and the laptop not doing so.) 

Any advice, or pointing me to a resource where I can find this info, or whatever else would be great. Thank you!

You can probably find better information in the Real Time Measurement and Control message board, but here is what I've been able to find out.  It used to be possible to change this, but has been disabled in recent versions of NI-RIO.  Unfortunately there really doesn't seem to be a work-around to change this on the cRIO, but maybe you can do it externally.

I have reposted the question on the Real-Time forum here:

Thanks David for your response, I just want to be as sure as possible before going another route.
