Depends what exactly you are trying to do. Looks to need 15 channels of
DMX control. How many do you have? As far as controllers go, you could go with a PC based solution (plenty of free software on the web), you would just need a
dongle to convert your USB port to
DMX output. The other way would be to
pick up a simple controller from Chauvet or ADJ, they start around $100. Cables depend on if you have a 5 pin device or a 3 pin device. Plenty on Ebay. True
DMX is 5 pins, but pins 4 and 5 were never given purpose. Therefore, there are a lot of 3 pin cables out there using standard
XLR mic connectors. For your purpose, either is fine, just make sure it is "
DMX" cable as compared to mic cable. Although mic cable often works fine on very simple rigs, you can run into some odd problems especially if you expand later. FYI - The first 3 pins on either 3 pin or 5 pin are wired the same. Also, 3 to 5 and 5 to 3 adapters are sold on Ebay and many other places if you end up with one thing using 3 and another thing using 5.
