Extron 232/75 (part number 26-433-09) — a 75 ft (22.8 m) 9-pin D male-to-female RS-232 control cable from the Extron 232 Series. Extron has retired this part number.

Seventy-five feet is the second-longest cable Extron built in this family, and it exists for the jobs where a serial device simply is not close to the rack: a projector at the back of a large hall, a display on the far side of a lobby, a processor in a closet two rooms away. The length is measured tip to tip, connectors included. All nine conductors run straight through with transmit on pin 2, receive on pin 3 and ground on pin 5, so nothing in the interface is dropped over the distance. The jacket carries an NEC CM rating for non-plenum pathways.
