What do the USRP2 LED lights indicate?

Hi,
I just got my USRP2 + WBX module.

I must say, for a new user, documentation is lacking for the hardware.

I searched the web for some info on setting up the hardware, just in
case, but found none, so opened it up and installed the card. A single
page getting started guide would have been useful, and improve first
impressions about the product.

I have a few questions:

a. What does the USRP2 LED lights indicate?

b. What is the difference between the WBX TX/RX and the RX2 connection?

c. If I wanted to test the system out quickly to receive FM broadcast
signals, to which connection on the WBX board should I connect the SMA
cable to?

The Ettus website has absolutely no user documentation for the hardware,
and it is not readily apparent to a new user that you can find
additional information about the hardware on GNU Radio.

E and F are the boot indicators for the hardware. The rest are unused.

b. What is the difference between the WBX TX/RX and the RX2 connection?

Either antenna for the UHD depending upon your selection.

For the gnuradio usrp2 driver, antenna TX/RX is always selected in a
receive only application. RX2 is selected for receive in a full duplex
application.

Much documentation is actually on gnuradio.org, here is a starting point

Thanks for the pointer. I just scrolled down to

http://gnuradio.org/redmine/wiki/gnuradio/USRP2GenFAQ

and saw the info on the LED lights. It would have been good if this was
put into a quick start guide for the USRP2.

I actually landed on the FAQ a couple of hours ago, but just glanced
through it, since I was looking for something to get me quickly up and
running, and missed out the part with the LEDS.

I’m trying to build GNU Radio from the git sources on Mac OS X 10.6.4
right now, and will try GRC shortly.
