Greetings all. We own an inventory of 10 Apollo ColorSmart 7.25" color scrollers. Lately we've run into a few issues, some of which are directly related to the power supply (PSU150w). However, we have seen another issue, and was wondering if anyone might have experienced this or knows of a corrective measure.
Situation is, we have 5 scrollers on a single 150w power supply, which is listed as being within tolerance of the power supply. There is about 125ft total of 4-pin DMX that connects the entire sequence, and the end of the chain is properly terminated at the power supply. We know we have some weak power issues because a rapid movement of all the scrollers on the line results in at least one dropping enough power that it forces it to reset. However, lately we have seen one in the sequence start to 'lag' behind the others. If all the others are set at a specific position on the string, this one is just slightly behind, straddling a line between an earlier part of the gel string and the one it's supposed to be on. Resetting this scroller has not solved the issue. Scrollers which are after this one in the chain do not lag.
This problem could be related to just that scroller. Given the production schedule, there has been no chance to test the connection system to see if another scroller put at that specific point in the cable chain would show the same symptoms. However, I can say that this particular scroller has never shown this tendency to 'lag' like this. I can also say that I have tested all the 4-pin dmx cabling in our inventory, and have not found any resistance or shorting which might lead to bad data.
So, brainstorming. Would this likely be related to the power supply, or is this a data loss issue at the scroller itself? It should be noted that the scroller which demonstrated this issue is also the scroller most likely along the chain to reset itself in the event of a large move of all the scrollers in that chain. Given the number of upcoming shows in January and February that we are going to be using our scrollers for, any direction that can be pointed as to what might be the issue would be extremely helpful.
Thanks as always!
