A DB25 25-pin serial female to female cable (1.5 meters) is designed to connect devices that both have DB25 female connectors. These cables are used for serial communication and are typically seen in industrial applications, legacy computer systems, and other serial devices requiring a 25-pin connection.

Key Features:

DB25 Female to DB25 Female: Both ends of the cable have female connectors.

Cable Length: 1.5 meters (approximately 5 feet).

RS-232 Communication: Most commonly used for serial communication with older devices.

Common Uses:

Connecting two serial devices that both have DB25 female ports (e.g., connecting a computer with a serial port to a peripheral like a modem or printer).

Data transmission between legacy equipment such as industrial controllers, data acquisition systems, or older printers.

Longer serial connections when a direct connection is needed between two devices with female DB25 ports.

DB25 Pinout Overview:

The pinout configuration for a DB25 serial cable is typically the same on both ends of the cable, as it's a straight-through connection.
