Extron 232/12 (part number 26-433-06) — a 12 ft (3.6 m) 9-pin D male-to-female RS-232 control cable from the Extron 232 Series.

Twelve feet covers the distance most rooms actually need between a control processor and the device it drives: rack to lectern, rack to a wall-mounted display, rack to a ceiling projector's serial port. Because Extron measures this length tip to tip, the connectors are inside the 12 ft, so the pull can be planned exactly. The wiring is straight through on all nine pins with transmit on 2, receive on 3 and ground on 5, so equipment expecting flow-control lines still sees them. The jacket carries an NEC CM rating for non-plenum pathways.

Key Capabilities

• 12 ft (3.6 m) finished length, measured tip to tip including the connectors.

Where It Is Used
