Overview
The Eaton Tripp Lite P440-89FM is a DB9-to-RJ45 modular serial adapter designed to connect equipment with a DB9 serial interface to twisted-pair Cat5e or Cat6 cabling. It converts a DB9 male connection to an RJ45 female connection and is intended for customized RS-232, RS-422, and RS-485 serial connections.
The adapter can be used with terminals, serial printers, modems, point-of-sale equipment, and other compatible serial devices. It provides a modular connection method that allows supported serial signals to be carried over readily available twisted-pair patch cabling.
Connectivity
The P440-89FM has a 9-pin DB9 male serial connector on one end and an 8-position RJ45 female connector on the other. The RJ45 connection is intended for twisted-pair Cat5e or Cat6 cabling as part of a compatible serial wiring configuration.
This is a modular serial adapter rather than a standard Ethernet network adapter. The RJ45 connector is used as the physical interface for compatible RS-232, RS-422, or RS-485 serial wiring and should not be treated as providing Ethernet functionality.
Configuration and Installation
The adapter is designed for customized serial cable configurations. Its color-coded wiring helps identify the individual conductors when building or troubleshooting a compatible serial connection. Slotted, knurled thumbscrews provide a secure attachment to the DB9 interface without requiring a separate screwdriver.
Applications
The P440-89FM can be used to connect compatible DB9 serial equipment to twisted-pair cabling in installations involving terminals, serial printers, modems, POS equipment, and other serial devices. It can also be used where a customized RS-232, RS-422, or RS-485 connection is required.
Key Features

DC Supplies Product Note
The RJ45 connector on the P440-89FM is used for serial signaling and does not make this adapter an Ethernet networking device. Before installation, verify the required RS-232, RS-422, or RS-485 pinout and wiring configuration for the equipment being connected.
