Built my first DMX Dongle, having a little trouble, and could use some help.
I built a V2 Dongle, had the PIC programmed, installed the CDM20600 driver, plugged in the dongle (came up initially as COM port 5), downloaded and installed Vixen, set up the Enttec DMX Usb Pro Add-in as COM5 at 115k, and when I tried to run a sequence I got the message "Access to the port 'COM5' is denied. Any ideas? I have attached pics of the dongle for reference...any help would be appreciated.
The picture shows that I have the test jumper in place...but I also tried it without the test jumper with the same result. Also, none of the LED's are on (should they be?). Also, I have not connected anything via the ethernet port.
