Tripp Lite P440-825FM DB25 to RJ45 Modular Serial Adapter, Male to Female, RS-232 RS-422

Save time and extend the life of legacy serial equipment with the Eaton Tripp Lite P440-825FM DB25 to RJ45 Modular Serial Adapter. This compact data transfer adapter converts a male DB25 serial port to an RJ45 female interface, allowing RS-232, RS-422 and RS-485 signals to run over standard Cat5e/Cat6 twisted-pair cabling. Ideal for security, surveillance and monitoring applications, the adapter lets you connect terminals, serial printers, POS devices and modems to centralized patch panels or network MUXs without costly hardware replacements. Color-coded twisted-pair leads simplify wiring and troubleshooting, while slotted, knurled thumbscrews deliver a reliable, tool-free attachment for mission-critical deployments. RoHS-compliant and backed by Tripp Lite’s lifetime limited warranty, the P440-825FM offers a low-cost, high-reliability solution for IT and physical security teams migrating or consolidating cabling infrastructure. Use it to streamline cabling in CCTV control rooms, access control stations or industrial monitoring racks—order now to integrate legacy serial devices into modern networked environments.
