A DB25 male to RJ45 adapter is a device that allows you to convert a serial connection from a DB25 (also known as a DE-25) connector to an RJ45 connector, commonly used in Ethernet networking. It enables the connection between devices that utilize different types of connectors.Specifications:Product name: DB25 male to RJ45 female moduleShell material: ABSWire: 1007 # 26 tinned copper wireRequires no external powerRJ45 Pin Outs: 1-Blue, 2-Orange, 3-Black, 4-Red, 5-Green, 6-Yellow, 7-Gray, and 8-WhiteDB25 Pin Definition: 1.SHIELD(Shield Ground); 2.TxD(Transmitted Data); 3.RxD(Received Data); 4.…
Key Features
- Transmit signals between your RS232 ports over CAT5, CAT5E, and CAT5 network cables. Transmits signals up to 100FT.
- RJ45 Pin Outs: 1-Blue, 2-Orange, 3-Black, 4-Red, 5-Green, 6-Yellow, 7-Gray, and 8-White.

- High quality alloy transmission port reduce the transmission impedance and interference, environmentally ABS material, super wear-resistant.
- The DB25 male to RJ45 adapter converts the pin configuration of the DB25 connector into the appropriate wiring scheme for an RJ45 connector, allowing you to establish a connection between devices that use these different interfaces. It is often used in scenarios where legacy serial devices need to be connected to a network infrastructure using Ethernet technologies.
