[Discuss-gnuradio] 16 digital I/O lines to control external devices like antenna switches

[Harley Myler]

Hi all,

Now that I have the USRP2 playing the university NPR station in my office, it is now time to get down to serious work.

Could someone please, in a nutshell, explain one of the features of the WBX (as one of the transceiver series) daughterboard that states:

16 digital I/O lines to control external devices like antenna switches

I would greatly appreciate just a nudge in the right direction, such as, where are these (connector?)?

How are they accessed (Python script, FPGA re-write, etc.)?

What I need to do is cycle through a set of receiving antennas, sampling signal from each one in a scan operation. If anyone has already done this I would dearly love to know your process.

TIA,

Harley Myler
