On a separate note, I assume you have 30-50dB of attenuation inserted into the lines between the TX and RX?Sure, screenshot of flowgraph is included. GRC version is 3.8, UHD is 4.1.0.
The E310 is being used in networking mode for some very basic testing. I have an E312 set up as to transmit a sine wave output (USRP Sink), which is connected over SMA to the E310 Rx ports (USRP Source). This works fine with a single Rx channel, and I can split the output of the transmitter and feed it to two different E310s, which works just fine as well. However, if I try to receive them both on the same E310, I get an error.

Could you perhaps share the flow-graph with the list, and which version of UHD, Gnu Radio you're using? Are you running on the E310 itself, or usingI tried both options; "A:A A:B" was invalid; it seems to accept "A:0 A:1", except that it gives me the same error message: "Runtime Error: port number 1 exceeds max of 0."Everything works fine with a single receive channel. I have also tried streaming a single receive channel from two different E310s, which works just fine as well. As soon as I try to add a second Rx channel, the flowgraph stops working.
"network mode" ?
