Extron 232/25 (part number 26-433-07) — a 25 ft (7.6 m) 9-pin D male-to-female RS-232 control cable from the Extron 232 Series.

At 25 ft the serial link stops being a rack accessory and becomes part of the room's infrastructure — rack to a far wall, rack to a ceiling-mounted projector, rack to a podium on the other side of a classroom. Extron measures this size tip to tip, connectors included, so the stated length is what you get to work with. All nine pins run straight through, transmit on pin 2 and receive on pin 3 with ground on pin 5, keeping full compatibility with devices that expect the auxiliary lines present. NEC CM rated, non-plenum.
