Extron 232/6 (part number 26-433-03) — a 6 ft (1.8 m) 9-pin D male-to-female RS-232 control cable from the Extron 232 Series.

Six feet is the longest length Extron still measures neck to neck, between the strain reliefs rather than tip to tip, and it is the most-specified size in the series for a reason: it reaches from a rack shelf to almost anywhere else in the same rack. Serial is still how a MediaLink Controller, an IP Link interface or a third-party processor drives Extron switchers, scalers and audio hardware, and this cable carries that traffic on a straight-through pinout — transmit on 2, receive on 3, ground on 5, with all remaining pins passed. The jacket is NEC CM rated for non-plenum spaces.

Key Capabilities

• 6 ft (1.8 m) finished length, measured neck to neck between the strain reliefs.
• 9-pin D male on one end, 9-pin D female on the other.
• All nine pins passed straight through with no null-modem 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, for fast tracing.
• NEC CM rated non-plenum jacket.

Where It Is Used

Rack-internal serial runs of moderate length: control processor to a matrix switcher at the other end of the bay, room controller to a projector interface plate, DSP to codec. Common in university lecture halls, corporate boardrooms, houses of worship, broadcast support racks and clinical video systems.
