Hi Folks, A few months ago I wrote a program for myself to better understand how the dmx string works and to try out visual basic 2008 express. With the help of Keith Tarpley with some beta testing and features were added to the program. Recently Phil asked for a tiger mode to correctly set the start address. I called it StartPattern, It will send the start address to Lynx/Tiger DMX controllers (not the LE) and it has some light patterns to test you lights and setup so you don't have to run Vixen or LSP while setting up your show. For Tiger mode just uncheck the Lynx mode checkbox. LOL I already see a change needed. To have the program "remember" which mode. It detects the dongle and shows the com port. At the moment if you have multi dongles or other boards using the FTDI drivers it only grabs the first one it finds which may or may not be the correct dongle port. This is good and possibility bad that future versions will have to fix. Like it will only "see" the first dongle and is limited to 512 channels Requires: .net framework 3.5, Microsoft PowerPack (I use that to create "lights" in the pattern mode to show the brightness level) along with FTDI drivers installed. If you don't have .net 3.5 or PowerPack it will grab them from Microsoft's website and install. Note: Powerpack is used in the pattern mode to show what condition the lights should be (off/on/dimming) I have a url link which the program will check for any updates and a zip file which will not check for updates http://mysite.verizon.net/vzepy09v/Start2/publish.htm Hope that makes sense and the program is useful Cheers Rick R. P.S. Just to let everyone know. I am not a professional programmer, I just enjoy writing small programs as a hobby. Most of my other programs were for the locksmith shop (former job) using Best IC cores pining.
