DB-9 (Serial/RS-232) Female to Female Cable (Null Modem)

The DB-9 (Serial/RS-232) Female to Female Cable (Null Modem) is specifically designed for direct communication between two RS-232 serial devices, such as computers, modems, or industrial equipment, without the need for a modem. In a null modem configuration, certain data transmission lines are crossed (such as the transmit and receive lines), allowing data transfer between devices. This cable is perfect for file transfers, configuration, and direct communication between legacy systems.
