First thing you need to do is run a DMX cable from the controller to a light, and another DMX cable from one light to the next. Ideally you would put a termintor in the open socket of the last light on the daisy chain, but with this small a rig, you may not need it.
Next set you lights to workable DMX channels. If you want both Tri Phases to always do the same thing at the same time, set the Tri Phases in DMX mode and set their DMX channels to 1. [Note: you can't get them to act in master/slave mode using DMX.]
Now whenever FIXTURE button 1 is lit, sliders 1~4 will control all the lights set to DMX channel 1. [That is unless the CH.PAGE button is switched so that its sending signals on channels 9~16. Your Tri Phases will only accept signals on the first four channels of a DMX address.] So sliders 5~8 won't do anything. Neither sliders 129~136 because they are designed to work on dimmer packs.
If you want to control each light independently of the other, set one Tri Phase's DMX channel to 1 and the other to 17. Now when "FIXTURE" button 1 is one, the first Tri Phase will be controlled, and when "FIXTURE" button 2 is on the second light will be controlled by sliders 1~4).
[If you are interested, you could set up the sliders on the left (1~4) to control one light and the sliders on the right (129~132) to control the other - but that is another story and not really the way the controller was intended to be used.]
After you've got your lights under control, you will want to learn how to use the scene buttons.
