[edit] dialing

i have a question about the DHDs dialing...i am always curious on how does the SGC teams know what to dial for earth?? since the symbols (i presume that its the constellations of that place) are different....thx! 70.70.209.80 17:48, 27 Apr 2005 (UTC)

That is one of the main differences between the Stargate movie and the series, in the movie the symbols on each stargate/DHD were unique, in both Stargate series the symbols on all gates/DHD's are the identical. In the movie a team would have to figure out the address. In the series the address of a Stargate is alot like a phone number able to be dialed from anywhere, with the exception of the point of origin (Chevron #7) which would be a unique from each stargate. --Silver86 21:05, 5 May 2005 (UTC)

In the episode Solitudes, Carter makes an explicit reference to this; she looks at the DHD of the new gate she and O'Neill have been inadvertantly routed to and, pointing to one symbol, says that since she's never seen that symbol before it must be the origin symbol for the planet they're on. (since that planet was Earth, this suggests that origin symbols actually uniquely identify the gate itself. That also fits in with the fact that you can put a gate on a starship and still use it at other locations.) Bryan 02:11, 6 May 2005 (UTC)
This is an issue with continuity as well as common sense. In some episodes 6 symbols are dialed with the center crystal acting as the point of origin. In others it acts as an "enter key". However, if the gate is spinning and is stopped on the final symbol it should activate without the need for the center crystal. Not only that but the DHD contains only 38 of the 39 symbols. This means that the P.o.O. symbol simply could not fit. -- Aarlin81 01:25, 3 May 2006 (UTC)
Interesting! I didn't know there were only 38 symbol keys on a DHD. It does make sense, though. Do you know of any images lying around that show a complete view of a DHD keyboard? That'd be something worth referencing in the article, IMO, provided it can be verified. And I'll have another look at the Solitudes scene at some point to see if I misinterpreted it. Bryan 01:44, 3 May 2006 (UTC)
Yes in fact I do. Here you go. Just click the images to enlarge. To save you from counting the glyphs on the inner and outer circles it's 19 and 19. Sorry but I couldn't find pics of the Pegasus gates and DHD (36 symbols instead of 39). I have editted the main article to note this. Perhaps a trivia section mentioning how 7 symbols are sometimes dialed as well as the PoO symbol in the season one episode Solitudes should be included. -- Aarlin81 04:43, 3 May 2006 (UTC)
Alright my head hurts. The more information I try to find on this the worse it gets. It seems that glyphs are often removed from the DHD to show a point of origin symbol (though it isn't really logical). The picture I linked to above shows the Abydos symbol but does not include Aquila. If this is to show dialing 7 symbols then the center button acts as an enter button. However, this seems only to make sense because the gates no longer spin (quick dialing). However, why would the gate not spin. What prompts the DHD to quick dial and not make the gate spin? Perhaps I shouldn't think about it too much. I'm afraid the more question I raise the less I'll be able to actually sit back and enjoy the show. Aarlin81 17:08, 4 May 2006 (UTC)
Most things in Stargate are consistant and make sense, however, this is not one of them. There are various valid contrdictions raised in the conversation above. I love thinking of Stargate as real sometimes, and thinking that there could be a stargate program happening in the world, (and im sure that you all do) but there is a point where we have to realize that it is fictional no matter how much we don't want it to be; and that the writers are not perfect. I and various people I know who over-analize the show find all sorts of inconsistencies. Some may be put in by mistake, others purposely to make the show better. Whatever the reason, they're there wheather we like them or not. Tobyk777 06:15, 17 May 2006 (UTC)
Ok, I've made some pretty big changes to the article, including a paragraph highlighing the contradictions of the central hemipshere. Aarlin81 17:47, 15 June 2006 (UTC)

The article was wrong on how the SGC dials the gate. I corrected it with info from '48 Hours'. Specifically, this quote: "In order to overcome the lack of a DHD we have to create the proper interface between the Gate and our computer. We generated a series of instructions based on electrical impulses to which the Gate crystals would respond. Now these were found mostly by trial and error over a great deal of time."208.228.100.69 20:09, 12 August 2006 (UTC)

When dialling from a DHD, you enter 7 coordinates and the center button acts as the 'enter' key. In an episode of SGA, mckay is dialling a stargate back to atlantis, and you can hear him counting as he dials the symbols (1-7) and then he presses the middle button. Also, i wanted to bring up what Aarlin81 said about the gate spinning. When dialling a stargate with a dhd, the stargate doesnt spin, the chevrons simply light up in sequence (a quick-dial as you put it) the stargate only spins when someone is dialling manually (or like the SGC, with a dialling computer, which is just a computerised way to dial the gate manually)--Zoobz19 (talk) 18:13, 21 February 2008 (UTC)
Oh and also i will mention that sometimes in the early episodes of the show, the stargate would spin when dialing with a DHD, and sometimes even when recieving an incoming wormhole, but this is more than likely just a continuity error, it was early in the show and they were probably still working everything out.--Zoobz19 (talk) 04:03, 7 April 2008 (UTC)

[edit] Picture

Erm, that's O'Neill, not the SGC computer dialing Abydos. LD 19:17, 26 September 2005 (UTC)

Fixed. An incorrect image had been uploaded with the same name, replacing the earlier one. I just reverted it. Bryan 04:23, 27 September 2005 (UTC)

[edit] A newer pic?

Shouldn't someone find a pic of the current dialing computer instead of the one from season 1?

[edit] Picture deleted

The picture has been deleted [1]. Should an alternative be used? — George C 16:24, 8 May 2007 (UTC)

Yes, I think so.

Vala M 20:33, 8 May 2007 (UTC)

Easier to just undelete it and add a fair use rationale, lack of which was the reason why it was deleted in the first place. Bryan Derksen 08:09, 9 May 2007 (UTC)

[edit] See Also Section

Do we really need that first lump of articles in the See Also? Most have noting to do with the actual DHD, and there's already that nicely formatted chart at the bottom. Revert? Opinions? It's popping up in other Stargate articles as well. --GaidinBDJ 14:50, 6 December 2005 (UTC)

Yeah, it's ludicrously huge. I'm taking it out, and I've noticed other people removing it from other Stargate-related articles as well. I say shoot on sight. Bryan 00:42, 7 December 2005 (UTC)

[edit] Center Button

In the episode "Allegiance" during the Tok'ra funeral, the Tok'ra don't dial anywhere. They just press the DHD's central button(is there a better term?), and the kawoosh happens, but then the gate shuts down. Thinktank

[edit] Earth's DHDs

What about the puddle jumper dhd?

  • shrug* I'm curious though, and where does it tell the fate of the Antarctic DHD? 217.159.163.207 14:30, 10 April 2007 (UTC)

[edit] Dialing computer

Since when does the dialing computer manage motors that turn the gate? I believe someone's mixed up the in show explanation and the real world one. I thought that when the gate receieves enough power, the inner ring unlocks and spins. In the real world, it is done by motors. Vala M 13:24, 17 April 2007 (UTC)

The dialling computer effectively manages a manual dial of the Stargate. The inner ring does not spin when the Stargate is dialled by a DHD. When the Stargate is supplied with sufficient power the inner ring unlocks and manual dialling can begin. The dialling computer then dials the Stargate by rotating the inner ring via motors. That's where all the steam coming from the Stargate machinery attached to the Stargate is coming from. I will forgo restoring my edits while this is discussed, but I am sure about this. Hermiod 10:04, 18 April 2007 (UTC)

Then please cite a source where this was mentioned as I do not remember it. That is how it's done production wise, but as for an in-show explanation, I don't think it is. Vala M 18:03, 18 April 2007 (UTC)

To be honest, I can ask you to do the same thing. It's quite clear how it works from actually watching the episodes. Watch what happens when the Stargate is dialled by the Dialling Computer - the inner ring moves. Watch what happens when it is dialled by a DHD. It doesn't move. Hermiod 20:00, 18 April 2007 (UTC)

From what I heard/understood. The capacitors feed energy to the gate until it gets enough and the inner ring unlocks and spins, then they lower the level of energy fed and it stops spinning, engages the chevrons and so on.

Vala M 20:29, 18 April 2007 (UTC)

Which episode was that process described in ? Hermiod 12:03, 19 April 2007 (UTC)

[edit] Maybe it is covered and I didn't notice but...

Can't Ascended beings access the stargate without a dialing device (Shifu (SG1 "Absolute Power") and Chaya (Atlantis "Sanctuary") WookMuff (talk) 10:20, 18 November 2007 (UTC)

Maybe fully ascended but not someone who is partially ascended like Anubis, remember in Lockdown that Anubis needed to take over someone's body in order to dial the gate.

Vala M (talk) 15:14, 18 November 2007 (UTC)

[edit] bothering me

In the section 'Milky Way DHDs' it discusses how the DHDs lack a glyph. What bothers me is this: "The glyph that is hidden under the pedestal of the Stargate, unseen along with the two chevrons, cannot be dialed by that DHD." Can someone tell me where this is mentioned in the show? When a gate is in a pedestal/ramp etc covering the two lowest chevrons, more than 1 glyph is obscured. Its the same on the stargate page too. --Zoobz19 (talk) 16:09, 8 January 2008 (UTC)

Thanks for pointing that out. That was a bit of inaccurate info and I removed it.

Vala M (talk) 17:18, 8 January 2008 (UTC)


Another thing that bothers me is that an explanation is never offered for why they couldn't just take a DHD from a world that's not using it. Even though each is missing a glyph, there's a 1/39 chance that any given DHD will be the same as Earth's originals. —Preceding unsigned comment added by 24.148.46.105 (talk) 09:15, 29 March 2008 (UTC)

There are several reasons. In the episode Avengers 2.0, a virus is uploaded to a DHD to put it offline. But then the DHDs auto update to all other DHDs, all gates with DHDs unoperational. Earth is the only planet that can still use their gate. Besides, where would the show be without "Chevron seven encoded. Chevron seven locked." --S II 087 (talk) 15:52, 4 May 2008 (UTC)

Would you stop posting these stupid copyright-related messages!? I had uploaded a few perfectly good, hi quality pictures, took time to fill out the 'rationales', only to find out that my material eventually got deleted. -- J7n

[edit] The name of the device

Here's one more inconsistency. How come the whole galaxy calls this device a "dial home" as if from the Tau'ri POV? The Stargate is a common mean of transportation to most other races. It is even possible that one's "home" cannot be reached by it. -- J7n —Preceding unsigned comment added by 83.99.184.75 (talk) 11:26, 15 April 2008 (UTC)

[edit] Missing Notability?

I came from the Stargate project main page, where it says this article is DHD is Missing Notability. Anyone care to elaborate?--S II 087 (talk) 15:55, 4 May 2008 (UTC)

Read WP:Notability (fiction). An IP removed the notability template without explanation this morning, I have added it back. – sgeureka t•c 17:28, 4 May 2008 (UTC)

Well I say the DHDs should be considered notable, they appear in every Stargate SG-1 episode I've seen, & I've seen approximately 50% of them. —Preceding unsigned comment added by 124.186.0.152 (talk) 11:43, 12 May 2008 (UTC)

The blast doors in the gateroom also appear in almost every episode, but that doesn't mean they need their own article. What both the blast doors and the DHD need is real-world information like how these props were produced and what their impact was on the real-world (e.g. reception, awards, spoofs in other shows, see WP:FICT), but I doubt that such information exists. If you have proof of the contrary, great, add it! That's why the template is there in the first place. – sgeureka t•c 12:11, 12 May 2008 (UTC)
