I have an issue with the 'DMX out' plug on a Design Spot 250. If I put any (I have tried several) lead into the DMX out of the DS250, I lose control of ALL the devices in the chain. I have 2 * DS250's, + 6 LED devices. They basically going into 'demo' mode & subsequently unusable for shows. It does not make any difference if the lead is connected to the next device, or not. There is no problems at all if I have nothing in the DMX out of the DS250. The DS250 is the last in the chain on the lighting bar of my church, but then goes on to the stage area, so I subsequently cannot use anything here. Any ideas !
