First a little background info: I am working with an ETC Ion and a variety of martin fixtures on the second universe and an MSI dimmer rack on the first. As far as I can tell everything is addressed correctly on actual fixtures and on the patch in the console. The problem: When I go to change the settings of any of the shutters whether it be to strobe or pulse or anything of that nature I find it will work for a few seconds and then the fixture or fixtures I am adjusting will reset themselves. That being said all of the other fixtures continue to work flawlessly(including shutter effects on any of the non mac300 fixtures) Any ideas as to what is causing this problem I have not had much time to investigate but I was wondering if anyone had any thoughts on possible causes or solutions. I know that that the 300's can work in 4 modes using anywhere from 9 to 13 channels. I believe they are in mode 4 using all 13 channels however I did not get a chance to double check that today, I will tomorrow. They are setup to run in mode 4 on the board. I am hoping that is my problem and a simple adjustment on the fixture will solve my problems, does my problem sound like a possible symptom to an incorrectly set mode?
