For a Show called Stargate, they sure don't dial the 'gate a lot...

For my latest project (read: insane piece of art...) I need to know how the Stargate in Atlantis works... what parts light up, what parts rotate...

I have seasons 2-4 here in Japan, but I cannot find an episode where we can actually see the dialing sequence. I've checked about 10 different episodes with no success, either they are already on the planet, or we just get the wormhole... I guess all the dialing sequences are in the 1st season?

I remember the clamp things light up as the chevrons are locked, but what is the sequence? Which one lights up first? Top? bottom-right?

Also, I think the part with the symbols did not rotate as the original Stargate did, but they lit up? Or something?

If anyone could point me to the right episode to look this up, or show me screencaps or a clip, or just explain it to me, I'd be very grateful.
