Hi AllDoes anyone have experience or more information on the zetlight products www.zetlight.com with specific reference to the z2500 product where the one light can control the others in a master slave config via a Ethernet cable between the units.Does anyone have more info on this product, what type of signal is sent on the cable, is it 0~10v???Reason for asking.... If I can find out what this signal is the I can possible interface it with my GHL profilux aquarium computer that can control lighting...
