Our DB9 Male to RJ45 Female Adaptor provides a cost-effective and flexible way to run serial data over long distances using standard Cat5, Cat5e, or Cat6 Ethernet cabling. This modular connector is essential for technicians and engineers who need to create custom RS-232, RS-422, or RS-485 serial links without the high cost of custom-molded serial cables.
Fully Customizable Pinout: Comes with un-terminated, color-coded flying leads, allowing you to manually configure the pinout to match the specific requirements of your hardware.
Modular RJ45 Interface: Features a standard 8P8C RJ45 female port that accepts any standard Ethernet patch cable for easy signal routing through existing building infrastructure.
Easy Snap-In Assembly: Designed for quick, tool-less installation; simply push the pre-crimped pins into the desired positions on the DB9 block until they lock.
Industrial-Grade Securement: Integrated knurled thumbscrews ensure a tight, vibration-resistant connection to your serial ports, maintaining signal stability in high-traffic environments.
Rugged Modular Housing: The durable beige PVC shell protects internal wiring connections and provides excellent strain relief for the attached network cable.
Connector A: DB9 (RS-232) Male.
Connector B: RJ45 (8P8C) Female.
Internal Wiring: 9 Pre-crimped, color-coded flying leads.
Hardware: Dual knurled steel thumbscrews.
Housing Color: Standard Industrial Beige.
Network Device Management: Connect your workstation to the serial console ports of routers, switches, and server hardware over long distances.
Industrial Control Systems: Bridge connections between a central PC and remote PLC units or diagnostic equipment in manufacturing environments.
Retail & POS Connectivity: Link point-of-sale terminals to remote receipt printers or customer displays using inexpensive twisted-pair cabling.
AV System Integration: Extend serial control signals to professional projectors, matrix switchers, and commercial displays.
How do I know which wire goes into which pin? Because serial pinouts vary by device, you should refer to your equipment's manual. Use the color-coded leads to keep track of your RX, TX, and Ground signals during the snap-in process.
Can I move the pins once they are snapped in? While the pins are designed to lock securely, they can be removed using a specialized pin extraction tool or a very small precision screwdriver if you need to reconfigure your pinout.
Does this convert my serial port into an Ethernet port? No. This is a physical adapter only. It allows serial signals to travel over Ethernet cables, but it does not convert serial data into TCP/IP network packets.
