Code emitted by an SG team member's G.D.O. Also called an "iris deactivation code" or "I.D.C.," the code is transmitted to the S.G.C. computer, instructing the iris to open and granting safe passage back to Earth. The code is a sequence of number that must be manually entered into the G.D.O. once a wormhole to Earth has been established. If necessary, iris codes can be locked out from the main computer. KEY EPISODE(S) - A Matter of Time - The gravity field of a black hole prevents SG-10's iris code from transmitting on a recognizable wavelength.  |
