I need advice setting up a master/slave configuration

Hi I hsve got 3 ADJ Dynasty Scans, I want to do the same, just link them with DMX cables, master to slave, but it wont work.I have checked out this link, but dtill cant work them.

This isnt working for you?
"Master-Slave Operation (Sound Active): This function will allow
you to link units together and operate without a controller. The units
will be sound activated. In Master-Slave operation one unit will act
as the controlling unit and the others will react to the controlling units
programs. Any unit can act as a Master or as a Slave.
1. Using standard XLR microphone cables, daisy chain your units
together via the XLR connector on the rear of the units. Remember
the Male XLR connector is the input and the Female XLR
connector is the output. The first unit in the chain (master) will use
the female XLR connector only - The last unit in the chain will use
the male XLR connector only. For longer cable runs we suggest a
terminator at the last fixture.
2. Master: Tap the “LEFT” or “RIGHT” arrow buttons until AUDIO is
displayed, then press either the “UP” or “DOWN” buttons to enter
the submenu.
3. Press either the “UP” or “DOWN” arrow buttons to select either
“On” or “Off”. Once you have decided, press the either the
“RIGHT” or “LEFT” arrow buttons to exit the submenu. The Slave
units will follow the Master once the Master has been programmed.
3. You may invert the pan and tilt functions by in the system menu
by following the directions on page 8."

Just a couple of things:

1: Your FIRST fixture(the one you don't use the DMX IN connection) needs to be your master while the rest MUST be set as slaves. It has to be that way. It can't be in the middle, it has to be at the begginning of the chain. So, do pay attention to how you're connecting these toegether, as it does make a lot of difference.

Related note: ADJ puts recommendations as to how many slave units you can hang off one master. This number varies by model, so do read the manual to get those numbers. Worse case is too many slaves and unpredictable operation but no damage.

2: While Jingles recommends standard XLR microphone cables, which will work, it's a better idea to use DMX cables. If you're just doing short runs, you're probably best off just using relatively short XLR microphone cables(say, 10 feet or less). I admit to running DMX-512 down 200-feet of XLR cable(single run) and then patching INTO that run from the controller to a an XLR to 1/4" TRS cable into a patch panel, that then went down that 200' run, which then went onto at least another 100' of XLR microphone cable, and didn't have any issues. I did this for 2 years, and never once had an issue, even without a DMX terminator. I however DO NOT recommend you replicate this.

3: A DMX terminator is never a bad thing, but it is generally recomended for any runs totalling more than a combined 100' of cabling when using DMX signalling. I have not seen any recommendations or requirements for a DMX terminator in a master/slave configuration though, so I'm going to suspect that it's not necessary. It shouldn't hurt. They are cheap to make provided you don't lose them. They are also a good thing to have in the tool box. When you get ready to use DMX, you're already prepared.
