Extron 232/50 (part number 26-433-08) — a 50 ft (15.2 m) 9-pin D male-to-female RS-232 control cable from the Extron 232 Series.

Fifty feet is a building-scale serial run: equipment closet to an adjacent room, rack to a ceiling projector at the far end of an auditorium, control processor to a device on another wall entirely. Extron measures this length tip to tip with the connectors included, so there are no surprises when the cable is dressed into a raceway. Wiring stays straight through across all nine pins, with transmit on 2, receive on 3 and ground on 5, so devices that watch the auxiliary control lines still see them at this distance. The jacket is NEC CM rated for non-plenum spaces.
