Is there a difference between an A4000 and an ATX Power supply?

the a3000 does and there is a jumper on the mobo that you can set to have the mobo produce the tick instead of the psu. i dont know about the 4000 though, but there may be a jumper like that. ill check my links to find 4000 jumpers

genlocks use the tick
as far as i can tell there is no tick jumper on the 4000, so you will have to use the pcb project to produce it.  on the 3000 if you set the jumper everything that uses tick works like normal, presumably with that project the 4000 will have similar capability
this and similar are the most complete 4000 jumper docs i could findhere
