Hi, I'm using a X310 with gnuradio with two 10-GbE interfaces. I'm trying to send and receive samples through a single SBX-120 If my project has a single USRP sink through the 10GbE interface 192.168.30.2, everything goes well. I can configure and send samples without much fuss. If my project has a single USRP source through the 10GbE interface 192.168.40.2, everything goes well too! :) I receive data and I'm able to plot it with gnu-radio. But... If my project has one USRP sink through the 10GbE interface 192.168.30.2 and one USRP source through the 10GbE interface 192.168.40.2, I'm getting the following error during configuration: ######################################### Generating: '/home/username/top_block.py' Executing: /usr/bin/python2 -u /home/username/top_block.py linux; GNU C++ version 5.3.1 20160413; Boost_105800; UHD_003.010.000.HEAD-0-g6e1ac3fc -- X300 initialization sequence... -- Determining maximum frame size... 8000 bytes. -- Setup basic communication... -- Loading values from EEPROM... -- Setup RF frontend clocking... -- Radio 1x clock:200 -- [DMA FIFO] Running BIST for FIFO 0... pass (Throughput: 1182.3MB/s) -- [DMA FIFO] Running BIST for FIFO 1... pass (Throughput: 1186.3MB/s) -- [RFNoC Radio] Performing register loopback test... pass -- [RFNoC Radio] Performing register loopback test... pass -- [RFNoC Radio] Performing register loopback test... pass -- [RFNoC Radio] Performing register loopback test... pass -- Performing timer loopback test... pass -- Performing timer loopback test... pass -- X300 initialization sequence... -- Determining maximum frame size... 8000 bytes. -- Setup basic communication... -- Loading values from EEPROM... -- Setup RF frontend clocking... -- Radio 1x clock:200 -- [DMA FIFO] Running BIST for FIFO 0... pass (Throughput: 1176.9MB/s) -- [DMA FIFO] Running BIST for FIFO 1... pass (Throughput: 1180.2MB/s) -- [RFNoC Radio] Performing register loopback test... pass -- [RFNoC Radio] Performing register loopback test... pass -- [RFNoC Radio] Performing register loopback test... pass -- [RFNoC Radio] Performing register loopback test... pass -- Performing timer loopback test... pass -- Performing timer loopback test... pass thread[thread-per-block[1]: <block gr uhd usrp sink (2)>]: EnvironmentError: IOError: Failed to sync DACs!

Hello, Specify both IP addresses in the arguments to both the source and sink blocks. GNU Radio and UHD are trying to create two separate connections to the same USRP which is causing the error.
