While watching some of the episodes of the Stargate Series, I have been wondering in what fashion the DHD interacts with the stargate itself.
I've have read some of the various questions and answers here on the science fiction stack exchange here, but only a few mention the possible workings of the DHD, and only this [question]: Why did The Ancients not include the remote dialing feature in the Milky Way Stargates? suggests that the DHD communicates wirelessly.
However, in all of the episodes, since the DHD is mounted on a pedestal and the "legs" of the DHD are buried within the ground, wouldn't it make more sense for the DHD to be physically wired to the gate, or for that matter any hardware trying to automate the dialing process?
