Profile: Goddard Design Co. offers lighting data display and verification systems. The MiniDMXter4 is a handheld DMX tester. It is powered by 2 AA batteries; & battery eliminator is available. It is very easy to use. The 7 button interface provides improved menu navigation, and the 40 character backlit display provides clear, plain language prompts. The MiniDMXter4's receive input is properly terminated at all times. The user may turn on the transmitter during reception to allow for loop thru mode (excluding pins 4 and 5). Both input and output support DMX512-A and RDM topologies. The MiniDMXter4 displays received levels in numeric or graphic format. The new, larger display allows for 4 slot levels to be shown numerically, or 32 slot levels to be shown graphically. DMX512 text reception is also supported. Recognizing the need for a handheld tester that handles basic RDM, we have included RDM responder address settings and basic configuration routines in the MiniDMXter4. The Smart Merge 4:2 takes four DMX512 universes and merges them into one or two Universes out. Most merges only allow a one to one merge, slot one of Universe one is always merged with slot one of Universe two, and so on. The house light dimmers may well live at slot 400 on the second Universe, and the slots needed to control with that effects controller may well start at slot 36. With most companies merges, such a product is a custom order .With the Smart Merge 4:2 it a matter of setting the front panel switches.
