General Description

These are extender cables for any device which uses a DB-9 connector. They are available in a variety of lengths and genders. All nine pins are extended, and the wiring is straight-through (pin 1 to pin 1, 2 to 2, ...) including a foil shield around the cable and connecting the shells. The conductors are 28AWG wire. These cables are beige in color.

Optional Extra-Long Jack Screw Kit

Winford now offers extra-long jackscrews as an accessory that can be purchased separately if daisy-chaining cables is desired. The existing thumbscrews would be removed and the long jackscrews installed in their place, and secured with the included nuts and washers on the back of the cable. See photo on right for example or order below. The jack screws are designed to accept the thumbscrews on a mating cable, helping secure the cable firmly in place.
