[USRP-users] auto start for e313

[liu Jong via USRP-users]

Hi all,
We have two pieces of E313,the difference of them is one of them insert sg1
imges and another insert sg3 image.
When we take DC power supply(12V) for e313,the  sg1's e313 would  auto
start,but for the sg3's e313,we must press power button,then e313 power on.
Is it normal?How could make auto start for sg3's e313?

Re: [USRP-users] SYNC For N310

[liu Jong via USRP-users]

Hi Marcus,
1.yes,we read it.But we could not find about a external devices.It is
possible that one of tx port of N310 as external LO when achieve 4 channels
sync receive?

2.From here:

http://files.ettus.com/manual/page_usrp_n3xx.html#n3xx_
getting_started_connectivity
we know that the SFP+ (sfp0, sfp1) ports are configured with static
addresses 192.168.10.2/24 and 192.168.20.2/24 respectively.

So i think we can connect to n310 with a SFP+ to RJ45 Adapter in sfp0.

but in fact,we even could not ping 192.168.10.2.

best regards
Jon

[USRP-users] DC power supply for E313

[liu Jong via USRP-users]

Hi all,
We know that when we insert network cable to e313,the e313 will power on
and press power button is not needed. Now,we take DC power supply(12V) for
e313,and we must press power button of e310 and then power on.
It is normal?How can we achieve power on and no press power button with DC
power supply for e313?

We plan to use 4 number of X310 for 8X8MIMO, and now we want to use the

on a x310 for processing?. Because the collected data comes from different
