Product Overview

DB9 RS232 SERIAL NULL MODEM - F/F

Expert Overview

The Rocstor Y10C880-B1 is a 2-meter (6.56-foot) null modem cable designed for serial data transfer between two DTE (Data Terminal Equipment) devices. This cable features a DB9 female connector on both ends, facilitating direct connection without the need for a modem. It is suitable for IT professionals and businesses requiring a reliable solution for tasks such as direct computer-to-computer communication, data transfer between older serial devices, or configuring network hardware via a console port where a null modem configuration is necessary. The black cable is engineered to reverse the transmit and receive lines, enabling two DTE devices to communicate effectively. This product addresses the need for a straightforward, dedicated serial connection in environments where standard straight-through serial cables would not suffice for DTE-to-DTE communication.
