How will it work with a homebrew QSD/QSE, probably like the softroc's?
I may eventually want to control one of the analog devices DDS boards
over the serial interface?<br>
I'd assume that hacking the code will be possible .. .<br>

Thanks & 73,<br>

Joe - thanks for the kind words on my code -- some clarifications in

Hi all,
I am currently working with Phil Harman on writing a manual on how
to operate the Janus/Ozy combo with the SDR-1000. Because of all the
discussions going on on the reflector about FPGAs, CPLDs, EEPROMs,
JTAG and what have you I (and I assume other mere mortals like me)
was expecting a separate initialization procedure would be required,
not to mention special cables. NOT SO!

For cables one will need a 25 pin male male straight thru cable to go
from Ozy to SDR 1K, 2x 1/8 stereo patch cables for IQ in and out
(assuming one connects mic and speakers direct to Janus). For the 25
pin male-male cable I'm currently using a 1 foot long home made
ribbon cable with IDC connectors - may not be ideal in a hi RF
environment. For the audio interconnect I'm using Radio Shack
#42-2497 (

<pre wrap="">Through our various back and forths on text etc I discovered that
Bill Tracey and he have really simplified it. Just to make sure that
anyone considering buying Janus/Ozy to work with the SDR-1000, but
holding off is not doing so due to wrong assumptions I thought I'd
share it with the group here.
Janus will be shipped with its CPLD pre-programmed, as will Ozy with
its EEPROM (someone correct me if I'm wrong). Ozy is connected to
the PC via a USB cable. All the relevant audio connections are made
to/from Janus and the SDR-1000, etc and for control a parallel cable
between Ozy and SDR-1000. Then just select Janus as you would any
other sound card in PowerSDR. That's it. Ozy's FPGA is then
automatically loaded through the USB and you're ready to roll.
Future updates to Janus's CPLD and Ozy's FPGA will all occur through
Ozy's USB connection.

The CPLD will be pre programmed, as will the Ozy EEPROM, however the
programming in the Ozy EEPROM will only be for self test - the Ozy
FPGA is configured over USB when we bring the device up for use with
PowerSDR.
There will actually be 2 selections/configurations one has to do in
PowerSDR -- one to select Janus/Ozy as the audio device and 1 to
select it as the control device. This is to allow one to use the
audio section without using the control section. I've not tested
using just the control section and not the audio section so that
configuration may or may not work.
Updating the CPLD via USB is a bit of code still to be written. I
believe it is doable, but the code (FX2, Ozy FPGA, PC side utility)
remains to be written

<pre wrap="">If you think about it, it's even simpler than installing a sound
card, as there is no driver to install, no mixer to deal with,
nothing. Just hook up and run.

One will need to install the libusb drivers to talk to Ozy. Not
quite hook it up and run but close.
