Dial Home Device

[Anissa T]

Built by the Ancients as a companion component to the Stargate. The DHD is the control mechanism for the Stargate; it enables a traveler to dial a destination Stargate address and request activation of the wormhole. The DHD directs the Stargate's inner ring to spin to the desired coordinates and assures that the address is valid and that all conditions are acceptable before allowing the wormhole to engage. If those conditions are satisfied, the DHD sends a power signal to the Stargate, causing the Stargate to use its stored energy to open the wormhole.
