You only need one do or one led for 2dof.A remote has one led, but most of the time they flash.If you have a webcam or other digital camera you can check this.If it flashes you can try it with freetrack but I doubt that it will give you the tracking you want.
That IR emitter led via the PL 2.5mm connector, I expect that it only gives ir-light when some ir-led is shining on it.It will do the same as what is shining on it.
