If you've been in chat or have had trouble getting a dongle or E1.31 bridge talking and have posted into the forum you've probably been linked to da_dmx and/or da_e131 which are 2 of the test apps that our very own David_AVD has created for us blinky heads over the years. These are free apps but there is a "donate " button on the pages if you feel like thanking David with a few dollars. The 2 bits of software should just about be the 1st thing you fire up for testing any new hardware in my humble opinion. They're so easy to use and take the sequencer setup out of the equation when testing new stuff for the 1st time. da_e131 takes almost nothing to get it going as it pumps out multicast data which "most" every E1.31 board should receive fine. All you need to do is select universe/s and channels and then use the faders. da_dmx is almost as simple. The app will detect either an open dmx or dmx pro usb dongle if it's attached. Go into View>Settings. Select the universe the dongle is going to control, the channel range that you want to control and then click "Open Port". You're now ready to use the faders, chasers etc. Click "Close Port" when done. You can change the repeat time which is how often packets get sent out and a few other things but most users will never need to play with these. da_dmx can control LOR dongles for controlling LOR boards in dmx mode. http://www.da-share.com/software/da_e131/ http://www.da-share.com/software/da_dmx/ These apps are so great that barely a day goes by that they aren't referred to in chat and/or a forum post. I personally use them for all testing and I also felt that they were "must have" apps so they were added to the latest ACL 101 revision.
