Where can I find documentation for using USRP 1.1 with the Ettus N210 device? The documentation that comes with USRP 1.1 has a tiny blurb on the N210 that points to the documentation for NI 292x devices for details. There, I find:
"For Ettus Research devices, use internal names to refer to the internal connectors inside the device case."
I'm trying to understand how to use the API to receive upon the LFRX-LF DC-50 MHz receiver daughter board. The two connectors on that board are labeled "RX-A" and "RX-B", but I can't get those names to work, nor can I get "RF1" or "RF2" to work (the names on the case).
Ultimately, I'd like to stream data from both connectors at the same time, if that's possible.
Support for the LFRX 0-30 MHz daughter board was just added to the NI-USRP driver in version 1.1 and documentation for this daught board is limited. While support for the LFRX is listed, I saw no mention to the LFRX-LF 0-50 MHz daughter board. I expect that your daughter board will work, but if not this may be part of the reason.
As far as the driver is concerned, the Ettus N210 and the NI-292x devices will be configured the same so there is not different documentation for the N210. I would try using RX1 and RX2 which are the names used for the other daughter boards.
