	The '''DF11 Communications Line Adapter''' performs two functions for [[serial line]] communication [[interface]]s on [[PDP-11]] computers: i) converts from [[transistor-transistor logic\|TTL]] signal levels to the [[voltage]]s, etc needed by a given serial line standard, and ii) produces the physical connector needed for that standard.

	A DF11 usually involves two [[DEC card form factor\|single-width]] cards, one holding the circuitry needed, and the other providing, sometimes with a cable plugged into a [[Berg connector]], the interface connector. At least one dual-width adapter (the DF11-B) existed, though.
