Looking for some help.
Keithr and I each have a newly assembled DMX Dongle 2.0 -- In my case I've gotten a PCB from RJ, and ordered Mouser parts. Keith on the other had obtained his parts from another form member.
I successfully programmed and verified the PICs for each of our units.
I installed the FTDI 2.8.14.0 driver. And I also installed Vixen 2.1.1.0.
Here are the problems:
I configure Steve's dongle for COM5... using the test feature in Vixen I try to turn on and off the channels -- all 512, and selectively on my DMX device. The lights continue unaffected, the lights continue to go through the controller's test sequence as if the cable was not connected.
I configure Keith's dongle for COM6... using the same feature I try to turn on and off the channels in the same way. In this case Vixen acts non-responsive, sometimes sluggish, but the channels and slider eventually move. The lights continue with the controller's test sequence without change.
I ALSO have a DMX programming cable from Harrison/David Moore... I connect that via COM4 and the same lights. This DOES work to change the light colors and intensity.
From all of this I assume that
1) the Vixen software is installed properly (proven by the programming cable)
2) Steve's dongle is broken on one way
3) Keith's dongle is broken in another
I've not done anything to alter Keith's dongle.
I HAVE attempted to remelt solder over each of the connections. I see no hint of a shorted circuit.
I did compare the parts on my dongle to Keith's and also to the pictures. The part IDs are the same for each dongle, and there is no observable difference from the pictures.
Any idea on what might be happening??
I'm going to start swapping out the USB cable now.
Thanks!
