A short 50 cm assembly with a 2.5 mm male stereo jack at one end and a DB9 female connector at the other. It is the kind of lead used to bring a compact jack-based interface — a headset, a radio programming port or a hand-held device — onto a D-sub connector, or the reverse.
Because a 2.5 mm jack and a DB9 are rarely found on the same equipment, this cable is built to order. Tell us how the pins should map and we will wire it to suit.

Two notes. A 2.5 mm stereo jack is the compact jack used on headsets, older phones, GPS units and some hand-held radios; a DB9 is normally a serial or multi-signal connector. Combining the two usually means a purpose-built adapter lead, so the pinout matters — confirm what each contact should carry. And check the jack: a 2.5 mm plug is smaller than the 3.5 mm used on most audio gear.
Typical applications
