Linux Installation - WinSDR

[pastor...@gmail.com]

Larry, I have specific questions for you if possible

Today I saw something that I hadn't seen before.  I went to the basement and noticed the Led wasn't flashing, but out.  So, I pulled the serial cable and the light began to flash again.  

1.  What specifically does the flashing Led tell me?

I have another usb to serial cable, and plugged it in, and the Led continued to flash as normal.  Not sure if the original cable is bad now.  May be some insight as to the functionality of the Led will help.  I can see the usb to serial cable with no problem, and do a loopback test with it and it's fine.  

2.  Using Minicom, are there any commands I can send from the terminal to get a response back from the a/d board?   I have a ver 2.7 as stated on the pc board.  It would be nice to see if I can communicate with the device from a terminal.  I have looked for documentation for this, but couldn't find anything. 

3.  I seem to remember seeing a schematic for the boards but can't find them now.  Is that something you would be willing to share with me so I can do some troubleshooting.  I now apparently have two bad a/d boards.  I have the gear to test if there is a schematic.  

As far as Linux.  I Have done all that I know to do to make sure this is working well.  com1 is mapped to /dev/ttyUSB0 in wine.  

And here are some things I have checked:

Any assistance would be incredibly helpful

Thanks Jeff

Hi,

There's a lot of fake serial to usb chips in many devices. This applies to older devices mostly. Since the manufacture changed the driver in such away that the driver does not work on the fake chips to deal with this problem. You can get a pci-express serial card for any new computer or a serial card for pci bus if your computer has that. Those work a lot better than a usb to serial connector if your WinSDR digitizer is a serial one.

Best regards,
Jón Frímann
