I am not really an N-series guy, so this probably won't be helpful.  Have you 
tried doing a uhd_usrp_probe on both devices and seen that the responses are 
consistent?

Subject: [USRP-users] Sequence Errors N200

Hi,
I am trying transmit using Ettus N200 (call it A) but getting this error 
message on the console

SSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSUSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

I looked for it on google and found these links
http://lists.ettus.com/pipermail/usrp-users_lists.ettus.com/2014-May/037495.html
http://lists.ettus.com/pipermail/usrp-users_lists.ettus.com/2012-July/032838.html

Both the links  suggested problem related to the gigabit port. Then I connected 
another USRP N200 (call it B) to the same laptop and tried transmitting using 
that as there were no such sequence error messages.

This makes me believe there is some problem with the first USRP, i.e., A.

Further I tried with different versions of UHD 3.11, UHD 3.15.. but its the 
same.

Receive is good only transmit is throwing error.

Not only with UHD, even in labview, when I transmit, I see nothing coming out 
from the N200 (A).

I am using SBXv2 daughter board.

Any clue!

Regards
