problem with UBX-40

[sonichxl]

At first I used NI USRP 2920,replace Wbx-40 with Ubx-40,program and working properly。When I run the same program In Ettus N210 add Ubx-40,it report error as:niUSRP Initiate.viA runtime or configuration error occurred. Code: 2410 Details : LookupError:Path not found in tree:/mboards/0/dboards/A/rx_frontends/0/sensors/lo_locked. How can I avoid this error? The software is LabVIEW 2015 and USRP 16.0. Thanks for your advice！
