you also want to consider that computers are not as reliable as light boards, if you are considering using this to run a show on. Also, you can get the free
DMX control software, but the actual hardware is VERY expensive. 3000+. The hardware runs in USB to
DMX conversion, external
DMX conversion boxes, and then the in-the-back-of-your-computer PC cards. All are pricey, although Chauvet, a more dance lighting company, sells a <1000$ external
DMX box, although I dont know how good that is, although I have never worked with I, but I do know that Chauvet is a reliable company with good products.
hope this help you, or anyone else interested
