DMX is the primary method for linking controllers, dimmers, advanced fixtures and special effects devices such as foggers and moving lights. A DMX controller is connected to fixtures or devices in a daisy-chain link.

If you have read the the What is DMX? But I am sure that most users use the 3-pin DMX cabling system. I know I do and infact I do not have any fixtures that are 5-pin. Please also be aware that some lighting fixtures require 5-pin cables to operate properly, these are some of the most expensive fixtures around and the extra 2 cables are used for a variety of reasons, some use them as power lines, some use them as spare data lines and some use them for their own proprietry reasons. Have spares, you will be supreised how easy it is to loose these.

Recent Martin Professional fixtures are fitted with a set of jumpers on the main PCB that allow you to reconfigure the pinout of the data connectors. If you have read the the What is DMX?

DMX is a standard for digital communication networks that are commonly used to control lighting and effects. It was originally intended as a standardized method for controlling stage lighting dimmers, which, prior to DMX, had employed various incompatible proprietary protocols. It quickly became the primary method for linking controllers such as a lighting console to dimmers and special effects devices such as fog machines and intelligent lights. DMX has also expanded to uses in non-theatrical interior and architectural lighting, at scales ranging from strings of Christmas lights to electronic billboards and stadium or arena concerts. It can now be used to control almost anything, reflecting its popularity in all types of venues.

In general, the final, empty, DMX out connector should have a DMX terminating plug attached into it, which is simply a ohm resistor joining pins 2 and 3 of the connector. Can be done with a Multi-meter but that is not as easy as plugging in a DMX tester. Data are sent with 1 start bit and 2 stop bits, LSB first. Please consult your user manual to see if your fixture has this option, and for instructions on how to change the settings. Terminating sometimes resolves this problem. Can be done with a Multi-meter but that is not as easy as plugging in a DMX tester. You do not have to connect you fixtures in address order they can be in any order you like and if you use a DMX splitter the same applies to that as long as they are on the same universe. DMX is the primary method for linking controllers, dimmers, advanced fixtures and special effects devices such as foggers and moving lights. Up to bytes can be sent, and it is the job of the receiver to count the bytes to keep track of the channels. The start of a packet is signified by a break of at least 88 uS.

Pins 4 and 5 are originally intended for feeding diagnostic data back to the DMX controller. The connectors with the holes are the out, think of it like a power socket, you cannot would not put you fingers in the socket and the power comes out of it. It is just something to be aware of, if you are getting problems and all your cables are good and it is terminated check to see if any are running near power cables. Have spares, you will be supreised how easy it is to loose these. You do not have to connect you fixtures in address order they can be in any order you like and if you use a DMX splitter the same applies to that as long as they are on the same universe. When connecting your fixtures with cables try to use the shortest cable possible, but not so short that it is stretched. Modern DMX controllers have libraries of data about fixtures telling them how to map attributes to DMX channels.
