Hi all,
Thanks for playing with the software!
Yes, you must install both to the same directory - I made a note about this
on the installer's wizard page where you select the destination directory,
but then again who reads that when you can just click Next :) Fixing that
properly is on the to-do...
Tides,
1.1.1 looks rather old now, you may wish to download the latest version
<http://wiki.spench.net/wiki/ExtIO_USRP>. This won't fix the issue you're
having, however. To do that, please download the official UHD installer for
Windows (grab the latest unstable):
http://code.ettus.com/redmine/ettus/projects/uhd/wiki/UHD_Windows
and use the N-series burner utility to update the FW/FPGA on your device.
E.g.
http://files.ettus.com/uhd_docs/doxymanual/html/page_usrp2.html#usrp2_loadflash
Then you'll be able to use it with the ExtIO.
Kind regards,
Balint

Subject: [USRP-users] USRP B2xx Transport Control for low-bandwidth
signals
Message-ID:
<CAC52AkD=go5enwx10frajpkycsbjpbw69gubx4qvehhaphg...@mail.gmail.com>
Content-Type: text/plain; charset="utf-8"
Hello,
I am experiencing frequent underflows with the B210 and ran into a few
questions regarding UHD USB flow control.
I am using a rate limited source (Audio Source) and generating a
low-bandwidth signal (256kS/s) and sending to the USRP. I notice a large
number of underflows (and LED flickering) on the B210 using this
configuration. If I interpolate and use a larger sample rate (1024kS/s) the
problem is greatly reduced. At 4096kS/s it is effectively gone. This
unfortunately doesn?t work well for what I need (the host cannot keep up
with this rate over USB and the necessary filtering to produce a suitably
clean interpolated signal) so I am hoping you can give me some help here.
As another data point the application works fine at 256kS/s on the B100 on
a non-disadvantaged platform but exhibits the same behavior using the B210.
Based on the UHD Transport Application Notes Ettus page, it looks like
there are 4 parameters that can be tweaked to modify behavior of the USB
transport mechanism. These do not appear to have much of an impact, if any
but I don?t quite understand which set I should modify for transmit
applications. I also noticed on the Ettus page regarding latency, there is
a note that the B100 has a ?flush timer? that also impacts the USB latency.
1. If I am attempting to transmit low bandwidth signals, which parameters
should be changed?
2. Does the flush timer note impact the B2xx and can this be set from the
gr-uhd interface (and if so, how)?
3. Am I overlooking something?
Thanks for the help,
Jacob

Hi Dan,
Would you be willing to release the CAD drawings for endplates that fit the
Hammond case? We can do our own milling, but if you've already adapted Ettus'
Takachi drawings to the Hammond case, it would save us (and other users) some
work.
Dan/Ettus - can you provide info (i.e., part numbers or dimensions) on light
pipes that would redirect LEDs to the panels? The Ettus plate drawings show
2.4mm diameter pipes but I don't know the length or standoff height. (EDIT:
found this thread that provides a link to a part number:
http://lists.ettus.com/pipermail/usrp-users_lists.ettus.com/2014-April/009372.html)
Thanks!

Hey guys,
Just wanted to let you know I am almost done with the CAD drawings for cutting
out the end caps on the Hammond
<http://www.digikey.com/product-detail/en/1455L1601/HM896-ND/1090708>
1455L1601<http://www.digikey.com/product-detail/en/1455L1601/HM896-ND/1090708>
metal enclosure (Hammond Schematics are
here<http://www.hammondmfg.com/pdf/1455L1601.pdf>). I am able and willing to do
the machining for a small price if you so desire. I have this case myself and
it looks great. Let m/e know if you are interested and I'll give you more
details.
For you Ettus employees, somebody mentioned an enclosure coming out a while
back - I don't know if you have made any progress on that, but if you are
interested in me doing some mass production or even some customized cases,
please feel free to contact me directly.
Sincerely,
- Dan
