Long-distance transmission, stable signal
Serial port to Ethernet cable transmission requires two components, using a pure copper CAT5/6 or higher pure copper twisted pair cable to transmit serial port signals over distances up to 20 meters.
✅ Product DescriptionThe DB9 to RJ45 Serial Adapter is a convenient solution for extending RS232 serial signals over Ethernet cabling. Designed to work in pairs, this adapter allows DB9 signals to be transmitted through standard CAT5 or CAT6 cables up to 20 meters, providing reliable and stable communication.
Featuring male-to-female DB9 connectors and RJ45 interface, this adapter supports a wide range of RS232 devices, including modems, industrial controllers, network switches, and communication systems.
Its zinc-alloy thickened terminals reduce resistance, minimize signal loss, and ensure long-lasting durability. With resistance to oxidation and corrosion, this adapter is built for heavy-duty and long-term applications.
Installation is plug-and-play, requiring no drivers or additional setup. Simply connect two adapters with a network cable to achieve extended RS232 signal transmission. Perfect for data centers, industrial environments, and communication setups requiring stable long-distance serial connectivity.
