InLine B-12225 serial cable DB-9 female to female 5 m beige

The InLine B-12225 serial cable DB-9 female to female 5 m beige is a reliable null modem cable designed for secure data transfer and device connectivity. With a generous length of 5 meters, it allows for flexible placement between connected hardware, making it a practical choice for various setups. The cable features a 5.4 mm diameter and is finished in a neutral beige color, blending easily into office or industrial environments.

Advantages

This serial null modem cable provides a stable connection for legacy devices and serial communication setups. Encapsulated connectors with knurl-thumb screws ensure a secure hold and prevent accidental disconnection during operation. The inclusion of standard 9-pin Sub-D female connectors on both ends allows for straightforward compatibility with existing hardware interfaces. Built with durable wire and shielded construction, it maintains signal integrity over the full 5-meter length.

Suitable for

• Connecting legacy peripherals and serial devices
• Industrial equipment communication and data logging
• Networking and configuration tasks requiring a null modem connection

When it may not be suitable

This cable is not designed for high-speed modern consumer interfaces such as USB, HDMI, or Ethernet, and it will not function as a standard data transfer cable for modern computers without appropriate adapters. It is specifically built for RS-232 serial communication and null modem applications.

Key specifications

• Cable length: 5 m
• Connector type: DB-9 female to DB-9 female
• Cable diameter: 5.4 mm
• Wire size: 28 AWG
• Pin assignment: 1-7+8, 2-3, 3-2, 4-6, 5-5, 6-4, 7+8-1, shield-shield
• Color: Beige

How to use

Ensure that both devices are powered off before connecting the serial cable. Align the 9-pin Sub-D female connector with the serial port on the first device and push it gently into place. Secure the connection by tightening the knurl-thumb screws manually. Repeat the process for the second device at the other end of the cable. Once both ends are securely fastened, power on your equipment and initiate the communication software.

What to consider before purchase

• Verify that both of your devices feature a 9-pin serial port interface
• Confirm whether your application specifically requires a null modem crossover cable rather than a straight-through cable
• Check the required cable length to ensure the 5-meter distance is sufficient for your setup

Usage recommendations

For optimal performance, route the cable away from heavy power lines and sources of electromagnetic interference. Avoid sharp bends or excessive pulling pressure on the connectors to maintain long-term signal reliability.
