The Black Box FA755 is a passive adapter kit designed to bridge the gap between legacy serial interfaces and modern network cabling. It allows you to terminate a DB9 male connector onto an RJ45 female port, enabling the use of standard Cat5e/Cat6 Ethernet cable for serial data transmission over longer distances than traditional serial cables permit. This is particularly useful in industrial automation, point-of-sale systems, or any environment where existing serial devices need to be integrated with new network infrastructure without replacing the serial hardware itself. The FA755 model facilitates this conversion for serial data streams.
This adapter is designed for use with any device featuring a standard DB9 male serial port and any network infrastructure terminating in an RJ45 female connector. It is compatible with serial communication protocols that operate over RS-232, RS-422, or RS-485 interfaces, provided the pinout is correctly mapped on both ends of the RJ45 connection. It is commonly used with industrial controllers, legacy diagnostic equipment, and certain types of network-attached serial device servers.
Installation involves connecting the DB9 male end to the serial port of your device and then using standard RJ45 modular connectors (e.g., Keystone jacks or patch panel ports) for the RJ45 female termination. Ensure proper pinout mapping is followed for the specific serial protocol (RS-232, RS-422, RS-485) being used. Incorrect wiring will result in no communication or data errors. This adapter is passive and does not require external power.
