At the start of the next DMX packet, 350-018 there is a Break, and this is then followed by the Mark After Break, this followed in turn by the Start Code and this again followed by the Mark Time Between Frames which is followed by the Channel Data, which is finally followed by the Mark Time Between Packets.
DMX can be transferred through various cable types, the three most common, are XLR5, XLR3 and RJ45 ethernet. Originally the standard was XLR5, as whilst DMX only utilised 3 wires, there were two extra cores, to allow for 640-801 possible expansion, and also seperate DMX cable, from microphone cable. However more recently, many manufacturers have started using XLR3 connectors as it allows the utilisation of microphone cable, which is often more easily available. RJ45 ethernet connectors began to be used, as it allowed the networking of all DMX devices, as both lighting desks, dimmers and some newer intelligent fixtures began to 640-816 have networking capability, a feature which could be found extremely useful in larger theatres.
More information regarding DMX, can be found on the U.S. Institute of Theatre Technology's website, as DMX512 is based on their standards
