    Comments about VTG 3-Pin DMX Terminator:

    If you've gone to the trouble of getting proper DMX-512 cabling for your intelligent lighting, don't forget the terminator! It's almost like forgetting to put the gas cap back on your car after filling up...it could just lead to trouble on down the road.

    On a review of Chauvet's DMX-512 data cables, I got into the differences between them and standard mic cable. Basically, you're operating at frequencies over 10 times higher than audio. And once you get up in that range of frequencies, you have to be concerned with things like reflections on the line. And that's what a terminator is designed to take care of.

    Without getting too technical here, a relection occurs when a data pulse hits the end of an open line. With nothing to absorb the energy, it literally reflects back up the line in the wrong direction. This has the effect cancelling part of the data stream out (or changing the data packets). [Note: I know that some EE's out there are grimacing at my descriptions here, but I didn't think that a product review was the appropriate forum for wave theory. Cut me some slack.]

    So...this is where a terminator comes in. In reality, it's just a XLR connector with a 110 ohm resistor between pins 2 and 3. You could make them yourself if you wanted to. But Chauvet has made this one for what I consider a fair price, and it's labelled!!! In fact, I wish they would use similar connectors on the ends of their DMX data cables so the sound guys wouldn't take 'em.

    If you've ever seen your DMX controlled lights start acting weird, change on their own, or just quit then you're likely seeing the effects of data corruption. Having the end of the cable run terminated is just one less thing you have to worry about when you're trying to get your lights working 10 minutes before a show. And if you've got more than 20' of cable between your controller and the last fixture on the chain, do yourself a favor and get proper DMX-512 cables.

      Comments about VTG 3-Pin DMX Terminator:

      The shrink wrap on the terminator I recieved was in the bag it came with vs, on the terminator it self. It was however easy to slide it back on and warm it up to shrink it to hold the 'unscrewable' base on.
