In my space I have an Ion, RPU, and RVI, all running 1.96 software. My console is set up as back up and my RPU is backstage as Master. Strangly enough right in the middle of a show, both my RPU and Ion lost control. I have had intermittent issues such as this but never with my console losing complete control, only with the RPU losing control, after which the Ion would take control as Master. My console is networked to my RPU through a switch and my RPU is plugged in to my DMX ports backstage. So in simple terms, my RPU which is run directly to DMX theortically should never drop control...right? Just thought I would see what other people's thoughts are...could this be an ION related issue?(Also my dimmers are not networked; they are CD80's). Thanks.
