Hey all, Just after some things to try and troubleshoot as my DMX items are not working. I used this stuff 2 years ago (missed last year) and it worked then. Dongle showing data going out, board showing it's receiving data, but lights not working. Checked polarity of lights and for boards with test function lights ok when test run. Using Vixen 3, but went back to Vixen 2 to do simple testing - no go on either. 2 dongles - ADV & Lynx - neither work. So far just trying 2 different boards - AVD 48DC and 27 channel from Ray Wu. Set start channel ok. About the only thing I haven't tried since they last worked is that it's a new computer. Do the dongles need drivers? When I connect them you get the little ding dong of a device connected, so figured it wasn't necessary. Anything else to check or try? Thanks heaps.
