A frame rig uses a complex set of coprocessors linked with a high-bandwidth datjack to interface with a complete, powered external armor, usually a frame or combat suit. These enhancements are required to fully comprehend and 'pilot' most rigged suits and armor; however, larger, more complex suits even require a greater series of cyberware.
This rig enables the cyber to interface with ultralight and light frames (exoskeletal body armor). Rigging is also necessary in effectively piloting a frame.
They are all neurolink technology and very expensive to outfit someone.
