InLine B-12226 Null Modem Serial Cable DB-9 Female to Female Beige 10 m

The InLine B-12226 Null Modem Serial Cable DB-9 Female to Female Beige 10 m is a dependable data transmission solution designed for seamless device connectivity. Featuring DB-9 female connectors on both ends and a generous length of 10 meters, this cable is engineered to meet standard serial communication requirements. The neutral beige color allows it to blend discreetly into various office and industrial environments, while the durable construction ensures stable and consistent performance for legacy hardware and specialized technical setups.

Advantages

This null modem cable offers a cost-effective and reliable way to link serial devices over extended distances without signal degradation. The inclusion of knurl-thumb screws ensures a secure, locked connection that prevents accidental disconnection during operation. Built with standardized pin assignments and encapsulated connectors, it provides dependable mechanical and electrical integrity. Furthermore, the bulk packaging approach minimizes excessive waste, making it an efficient choice for installations requiring multiple connections.

Suitable for

• Connecting legacy computers to older serial peripherals
• Industrial automation and machinery maintenance
• Networking and configuration of networking hardware via serial console ports
• Point-of-sale terminal setups and scientific instrument data logging

When it may not be suitable

This cable is not designed for high-speed modern consumer data transfers such as USB or HDMI applications, as it strictly supports RS-232 serial communication standards. Additionally, the 10-meter length may be excessive for simple desktop setups where shorter cables would prevent unnecessary cable clutter.

Key specifications

• Cable length: 10 meters
• Connector type: DB-9 female to DB-9 female
• Cable diameter: 5.4 mm
• Wire gauge: AWG 28
• Color: Beige
• Connector fastening: Encapsulated with knurl-thumb screws

How to use

To use the serial cable, ensure that both connected devices are powered off to prevent electrical damage during connection. Align the DB-9 female connector with the serial port on the first device, gently push it into place, and tighten the knurl-thumb screws securely. Repeat the process for the second device at the opposite end of the cable. Once both ends are firmly secured, power on your equipment and initiate serial communication through your software or terminal interface.

What to consider before purchase

• Verify that both of your devices feature standard 9-pin DB-9 serial ports and require a null modem crossover pin configuration.
• Measure the distance between your devices to ensure the 10-meter length is appropriate for your layout.
• Confirm that your hardware application supports RS-232 serial data protocols.

Ensure cable routing avoids sharp bends and heavy foot traffic areas to maintain optimal signal longevity and mechanical integrity over time.
