Black Box 10ft RS232 Shielded DB9 Female to Female Null Modem Cable (Gray)

The Black Box EYN257T-0010-FF is a 10-foot RS232 shielded null modem cable designed to connect two devices with DB9 female ports for direct serial communication. It is built to facilitate reliable AT-to-AT file transfers and other serial data exchanges by crossing the necessary pins to meet RS-232 standards. This cable is especially useful in environments where stable and interference-free serial connections are critical, such as IT departments, industrial setups, or legacy system maintenance.

Constructed with a gray PVC jacket and metal EMI/RFI hoods, the cable offers strong protection against electromagnetic and radio frequency interference, ensuring data integrity over longer distances. Its 115-ohm nominal impedance at frequencies of 1 MHz and above makes it suitable for high-frequency data transfer applications. Whether you are setting up new equipment or replacing an old cable, this null modem cable provides a dependable connection that supports consistent performance in demanding serial communication tasks.

This cable is ideal for technicians, engineers, and anyone working with serial devices that require a female-to-female DB9 connection, such as modems, routers, or industrial controllers. Its length and shielding make it a practical choice for both office and industrial environments where signal quality and durability matter.
