Monoprice 100444 15ft DB9 Serial Extension Cable Male/Female

The Monoprice 100444 15ft DB9 Serial Extension Cable is a practical solution for anyone who needs to extend a serial RS-232 connection between devices. Featuring a DB9 male connector on one end and a DB9 female connector on the other, it functions as a straight-through extension—simply plug it between your existing serial cable and the target device to add 15 feet of reach. This is especially useful in server rooms, industrial settings, and retail environments where serial-connected equipment like managed switches, PLCs, or point-of-sale terminals may be positioned farther from the controlling workstation than a standard cable allows.

The cable's molded connectors provide solid strain relief at the junction points where cables most commonly fail, helping to extend the working life of the connection. At 15 feet, the cable stays well within the RS-232 specification's reliable operating distance for standard baud rates, so signal integrity is not a concern under normal conditions. As a Monoprice product, it offers a cost-effective alternative to name-brand serial cables while maintaining the basic build quality needed for dependable everyday use in commercial and industrial applications.
