I have a KLS scanner. The DMX dipswitches go by 1, 2, 4, 8, 16, 32, 64, 128, 256, (Also a pan invert, tilt invert, and 10% lamp saver). They have a gobo wheel, color wheel, pan, tilt, and lamp intensity. So that would be a 5 channel scanner? I assumed if 128, you just flip 128 up only. If you want 133, you would flip 128, 4, and 1? Basically I am trying to figure out how to connect these to an Ion ETC light board and have had no luck. I was dimming/turning on/off every channel on the light board to see if the lights would respond and nothing happened. I also got a volt meter and the DMX signal was changing with the channel intensities changing. Is it ABSOLUTELY necesary to have a terminator? Even if termination was needed, wouldn't the first light work, and only the last light not? These are KLS SE204 scanners. I can't find any documentation. Thanks abunch for the time! Marshall
