So my high school has a old AAS system from etc which was put on a possibly older dimmer rack (Analog Address System - Electronic Theatre Controls). the cards are breaking left and right, but that is a different issue.
Recently we were using the dmx input and the bypass function on it to control it through an entec usb pro. this works flawlessly, but one day i hook it up and the system just decides to not listen to dmx anymore, but the anolog control station still works. we are getting an oscilliscope on Thursday and i wanted to know is it safe to hook up to the dmx output on the dongle (i dont want to short anything), in order to see if the dongle broke or did the board break. did anyone ever even hear of dmx breaking on the board, or is it most likely the dongle. (i tested the dmx cord with a ohm-meter and a paper clip, and there is continuity in all the leads, although was surprised to find the input and output crossed.
with the osciliscope should i ground it on the ground in cable or the ground on board in the ASS, or the DATA - pin?
my other question is; is it possible to buy an anolog 8 channel board for this system, or does it just not exist anymore. we could really use the board to set up scenes and just 'take control' and have it fade to that scene
