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

The InLine B-12226 null modem serial cable provides a reliable solution for connecting serial devices over extended distances. With a generous length of 10 meters, this cable allows flexible placement of hardware in professional and industrial environments. It features durable DB-9 female connectors on both ends, designed to ensure secure attachment and stable signal transmission. The cable is finished in a neutral beige color and features a slim 5.4 mm diameter, making it suitable for discreet routing along walls or through cable management systems. Each unit is supplied as a bulk pack containing 15 individual cables, providing a cost-effective option for larger installations or ongoing maintenance needs.

Advantages

This null modem serial cable is engineered to deliver consistent and stable data transfer between compatible serial devices. The 10-meter reach eliminates the need for additional extensions, reducing potential points of failure in the signal path. Encapsulated connectors equipped with knurl-thumb screws ensure a firm and secure connection that resists accidental disconnection during operation. The inclusion of integrated shielding helps minimize electromagnetic interference, maintaining data integrity even in electrically noisy environments. Delivered in a bulk pack format, the product offers a practical and economical choice for commercial deployments, reducing excessive packaging waste while maintaining high manufacturing standards.

Suitable for

• Connecting legacy serial equipment over long distances
• Industrial automation and control system setups
• Professional IT and networking installations requiring direct device communication
• Bulk deployment for technical workshops and service centers

When it may not be suitable

This cable is not designed for connecting devices that require standard straight-through serial connections, as it specifically utilizes a null modem pinout for cross-communication. Additionally, it is unsuitable for connecting to modern computers or peripherals that lack traditional 9-pin serial ports, unless appropriate hardware adapters are used.

Key specifications

• Cable length: 10 m
• Connector 1: DB-9 female
• Connector 2: DB-9 female
• Cable diameter: 5.4 mm
• Wire size: 28 AWG
• Color: Beige
• Quantity per pack: 15 pieces

How to use

To use the InLine B-12226 null modem serial cable, ensure that both connected devices are powered off before making any physical connections. Align the DB-9 female connector with the serial port on the first device and push it firmly into place. Secure the connection by tightening the integrated knurl-thumb screws manually until snug. Repeat the same procedure for the second device at the opposite end of the cable. Once securely attached, power on your equipment and verify that communication is established through your operating system or device management software. Avoid sharply bending the cable or placing heavy objects on it to maintain optimal performance and longevity.

What to consider before purchase

• Verify that your devices feature standard 9-pin DB-9 serial interfaces
• Confirm that your application specifically requires a null modem crossover pinout rather than a standard straight-through cable
• Ensure the 10-meter length is appropriate for your physical layout without creating excessive slack

Usage recommendations: Store unused cables in a cool, dry place away from direct sunlight and moisture. When routing the cable, avoid sharp corners and pinching to prevent internal wire damage. Ensure that thumb screws are tightened only by hand to avoid damaging the connector threads on your equipment.
