[USRP-users] Problem accessing E310 via network

Hello James,

By default the E310 is intended to have the signal processing done locally
on the device. If you want to use it from a remote host then you need to
recompile UHD with E310 network mode support and run the the network mode
daemon on the device.

http://files.ettus.com/manual/page_usrp_e3x0.html#e3x0_network_mode

The bandwidth available in this mode is very limited, perhaps 4 MSPS.

Regards,
Derek
