Description

Black Box FA043 AT Adapter - DB9 Female TO RJ45

Overview

The Black Box FA043 adapter converts a standard DB9 serial port to an RJ45 Ethernet connector. This allows you to extend serial device connections over standard Cat5e/Cat6 cabling, ideal for integrating legacy serial equipment into modern IP-based infrastructure or for extending serial data transmission distances beyond the limitations of RS-232. Its compact form factor and passive operation simplify deployment in tight spaces or when running new cabling is impractical. The FA043 is TAA and GSA compliant, meeting government procurement requirements.

Compatibility

This adapter is designed for use with any device featuring a standard DB9 male serial port, such as industrial controllers, network switches, routers, modems, and console servers. It facilitates connection to devices with an RJ45 serial port or to other adapters that convert RJ45 back to DB9. It is compatible with standard serial communication protocols and requires no drivers or software, functioning as a passive physical interface converter.

Installation Notes

Connect the DB9 female end to the male DB9 port on your serial device. Connect a standard Cat5e or Cat6 Ethernet cable to the RJ45 port on the adapter. The other end of the Ethernet cable should connect to a corresponding RJ45-to-DB9 adapter or directly to an RJ45 serial port on another device. Ensure the pinout of the RJ45 connection matches the serial device requirements; this adapter typically follows standard serial-to-Ethernet pinout conventions.
