I just purchased a used colorstar 3000 to replace a 2000. I am familiar with the 2000 but have no idea how to hook the 3000 to my enlarger so I can use it as a timer also. There is no recepticle for a plug in this unit. It has a recepticle for the sensor and another for a footswitch or other accessory the power cord and another large cord with 5 prongs on the end. It was used on a Super Chromega enlarger or so I was told. Where would or how would I plug into my LPL 6700 enlarger. It only has the power cord to the enlarger head and nothing else. I used the 2000 which has a recepticle for the power cord from the enlarger but this 3000 has none and that is a bit confusing to me. Do I need some other adapter or something in order to hook the enlarger into it? I purchased this unit for the extra features over the 2000 but if I can't use it to time the exposure then it is kind of a waste. Anyone have one of these units and can you tell me how your enlarger is hooked up to it. Thanks for any help since this is really driving me nuts.
