you might try disabling and removing the existing com driver, and installing the FTDI driver.

the current driver is later than that described in the wiki. 2.08.14

what is the correct baud rate?

Post by: caretaker on March 05, 2012,

Correct Baud rate with the Lynx Dongle is 115200 either DMX or Pixelnet.  Because RJ designed a dongle that uses it's own processor instead of your computers it can support the high baud rates between the computer and itself.


Edited to add the 115200 is for either DMX or Pixelnet

would that still be 115200 for dmx as well?

Yes.  The PC is sending out the same data to the dongle so the comm rate is the same.

I thought Pixelnet was 1M baudrate?

The baud rate is ignored with the USB module it sends data as fast as it can over the usb port. It just needs this since it fakes a standard port for software to see.

RJ, thanks for enlightening me as I did not know that. That's what I love about this site is you learn so much cool stuff here.
