Hi there. I am fairly new to using ILDA and QuickShow. My question is regarding extending the cable(s) so I can place my lasers on a truss. I am sure one cable or the other is better recommended to prevent line losses. From reading some of the posts, I see there are actually 2 different DB25 cables, one specific to ILDA. So, for all you purists out there, should I use a say 35' USB cable with a built-in repeater, or should I use a 35' DB25 extension cable ? I have purchased many different cables from mycablemart.com as I have found them to be very reliable, and inexpensive, and would like to get one or the other ordered quickly. Thanks very much !!
