Extron 232/10 (part number 26-433-05) — a 10 ft (3.0 m) 9-pin D male-to-female RS-232 control cable from the Extron 232 Series. Extron has retired this part number.

Ten feet is the length that gets a serial link out of the rack and across a credenza or under a table. Extron measures this size tip to tip, connectors included, so the number on the label is the real span. The wiring is a straight-through 9-pin D pinout rather than a null modem: transmit sits on pin 2, receive on pin 3, ground on pin 5, and every other pin is carried end to end, which matters for equipment that watches the handshake lines. Behind it all is an NEC CM rated non-plenum jacket for ordinary room and rack pathways.

Key Capabilities

• 10 ft (3.0 m) finished length, measured tip to tip including the connectors.
• 9-pin D male to 9-pin D female termination.
• All nine pins passed straight through with no crossover.
• Pin 2 transmit, pin 3 receive, pin 5 ground per Extron's cable guide.
• Color-coded conductors, brown on pin 1 through black on pin 9.
• NEC CM rated non-plenum jacket.
• Retired Extron part number — useful for matching an existing installed system.

Where It Is Used

Serial control that leaves the rack: processor to a display or projector at the front of the room, controller to a lectern device, rack to a nearby wall box. Typical in classrooms, training rooms, courtrooms, worship platforms and clinical reading rooms.
