Black Box Modular Adapter Kit DB25 Female to RJ45 Female (Black)

The Black Box FA4525F-BK is a modular adapter kit that converts a DB25 female RS-232 port to an RJ45 female modular jack. It arrives unassembled, giving you full control over the wiring layout so you can match the exact pinout of your devices. You can build it in 6-, 8-, or 10-wire form, making the same kit suitable for anything from simple control signals to more fully populated serial connections.

Installation is straightforward. The included thumbscrews let you secure the adapter to rack-mounted gear, desktop equipment, or test benches without reaching for extra tools. Because the housing is black, technicians who color-code their cabling systems will find it easy to identify and route the adapter in busy racks or patch panels.

In daily use, the kit is a practical bridge between legacy serial hardware and modern structured cabling. Network administrators can run console lines through existing Cat-5 or Cat-6 runs, field service engineers can assemble the adapter on site to match unexpected pinouts, and lab technicians can keep a few kits on hand to reconfigure test setups quickly.

If you maintain equipment that still relies on DB25 serial ports but prefer the convenience of RJ45 patch cables, this adapter offers a clean, dependable solution that you can tailor to each job.
