README : About the Perseus support in Spectrum Lab
-------------------------------------------------------

Recommended: Instead of using the possibly outdated "built-in" support
for Perseus (see "OLD DESCRIPTION" below), you should use the 
Winrad-compatible ExtIO-DLL for Perseus from the Perseus website.
This used to be at http://www.microtelecom.it/perseus/software.html ,
look for "ExtIO DLL for Winrad", for example ExtIO_perseus2v3b.zip .
Unpack the entire content of the zipped archive into the directory
where Spectrum Lab has been installed (precisely: the folder where
'SpecLab.exe' is located).
This way, SL can always use the latest FPGA data available from
the manufacturer of Perseus.

OLD DESCRIPTION - USED WITHOUT THE WINRAD-COMPATIBLE "ExtIO"-DLL :

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -


To use Spectrum Lab "directly" with Perseus (without a Virtual Audio Cable),
you need to copy at least the following files into this directory :

perseus125k24v21.sbs - Perseus receiver FPGA configuration data (125 kS/s)
perseus250k24v21.sbs - Perseus receiver FPGA configuration data (250 kS/s)
perseus500k24v21.sbs - Perseus receiver FPGA configuration data (500 kS/s)
perseus1m24v21.sbs   - Perseus receiver FPGA configuration data (1 MS/s)
perseus2m24v21.sbs   - Perseus receiver FPGA configuration data (2 MS/s)
perseususb.dll (*)   - interface between the application (here: Spectrum Lab)
                       and the Perseus USB drivers .

 (*) Note:  PERSEUSUSB.DLL is not the USB driver for Perseus itself !
            The USB driver(s) -now WinUSB- must be installed from the 
            CDROM provided by Microtelecom, or from the Perseus website.
     When changing from the old Cypress USB drivers to WinUSB,
     don't forget to overwrite perseususb.dll with the newer version !

In Perseus V3.0, the following FPGA files with 'soundcard compatible' sampling rates
were added. Spectrum Lab can also use them. The lower sampling rates greatly reduce
the CPU load, so use one of these if you don't need a broadband display:
perseus48k24v31.sbs  - Perseus receiver FPGA configuration data for 48 kS/s
perseus96k24v31.sbs  - Perseus receiver FPGA configuration data for 96 kS/s
perseus192k24v31.sbs - Perseus receiver FPGA configuration data for 192 kS/s .

SpecLab will first try to load the above files. 
If they don't exist, the program will try one of the "older" files below:

perseus125k24v11.sbs - older Perseus FPGA configuration data (125 kS/s)
perseus250k24v11.sbs - older Perseus FPGA configuration data (250 kS/s)
perseus500k24v11.sbs - older Perseus FPGA configuration data (500 kS/s)
perseus1m24v20.sbs   - older Perseus FPGA configuration data (1 MS/s)
perseus2m24v20.sbs   - older Perseus FPGA configuration data (2 MS/s)


You will find these files in the directory of original PERSEUS software 
 by Microtelecom. It is on the CDROM you received together with the radio.
 Make sure your PERSEUS software is not older than V1.1b (08/2008) .
 The 2 MS/s setting may be too fast for the real-time audio filters in SpecLab,
 but it *may* work for the spectrum analyser if your PC is fast enough .
 Don't try to rename the FPGA configuration files if the names have changed
 in future versions of the PERSEUS software - this won't work !
 Instead, the old files (which have been tested with Spectrum Lab) may
 still be available on the Microtelecom site in the Perseus DLL for Winrad.


The USB drivers (required to communicate with the PERSEUS receiver)
must be installed on your system. If not already done, please install
the original PERSEUS software (c) Microtelecom, read the disclaimer 
and the release notes, check if everything works with the original 
PERSEUS software, and *after that* try to get Spectrum Lab running
with PERSEUS . 

Again, Spectrum Lab won't run with Perseus if you didn't install
the drivers from the original Perseus software.

For copyright reasons, and to make sure you always use up-to-date drivers,
neither the PERSEUS USB drivers, nor the interface DLL, nor the 
FPGA configuration data    are included in the Spectrum Lab installation file.

To use Perseus as the input device for Spectrum Lab, select in the main menu:
  "Options"..."Audio Settings". Open the combo list under "Audio Input Device",
  and select "PERSEUS". 
Or select one of the preconfigured settings for Perseus, like this:
   "Quick Settings"..."Image cancelling DC receivers (I/Q)"..."PERSEUS" . 

More information about how to control and use PERSEUS in Spectrum Lab
is in the SL help system, see ..\html\perseus.htm  .

Many thanks to Nico Palermo for his assistance, and for providing the SDRDK .

Now enjoy your Perseus, and don't miss the Nico's "original" Perseus software,
which is easier to use if you don't need Spectrum Lab's "special" processing.
