InLine B-12224 Serial Cable DB-9 Null Modem 3 m Beige

The InLine B-12224 Serial Cable DB-9 Null Modem 3 m Beige is a reliable connection solution designed for secure serial communication between compatible devices. With a length of 3 meters and a standard beige color, this null modem cable is built to facilitate efficient data transmission in various technical environments. The cable features female DB-9 connectors on both ends with integrated knurl-thumb screws for a secure and stable connection during operation. Supplied in an environmentally friendly bulk pack of 35 pieces, it offers an economical choice for setups requiring multiple serial connections.

Advantages

This serial cable provides a dependable physical link for legacy and specialized hardware that relies on serial communication protocols. The null modem configuration allows two DTE devices to communicate directly without requiring a standard modem in between. Encapsulated connectors with thumb screws ensure that connections remain secure and resist accidental disconnection. The 3-meter length offers sufficient reach for connecting equipment placed at a moderate distance from one another. Additionally, the bulk packaging reduces excess waste while delivering standard InLine quality for professional and personal applications.

Suitable for

• Connecting serial printers and legacy terminal equipment
• Data exchange between older computers or industrial control systems
• IT service and maintenance setups requiring multiple null modem cables
• Direct device-to-device serial communication configurations

When it may not be suitable

This product is not suitable for modern consumer devices that lack serial DB-9 ports, such as standard modern laptops or home desktop computers without a dedicated serial expansion card. It will also not function as a standard straight-through serial extension cable due to its cross-wired null modem pinout configuration.

Key specifications

• Cable length: 3 m
• Connector 1: DB-9 female
• Connector 2: DB-9 female
• Wire gauge: 28 AWG
• Cable diameter: 5.4 mm
• Color: Beige
• Quantity per pack: 35 pieces

How to use

Before connecting the cable, ensure that both devices are powered off to prevent potential electrical damage to the serial ports. Align the DB-9 female connector of the InLine null modem cable with the corresponding male serial port on the first device, ensuring correct pin orientation. Push the connector gently into place and tighten the integrated knurl-thumb screws securely with your fingers. 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 configure the communication software settings as required for serial data transfer.

What to consider before purchase

• Verify that both of your devices feature compatible 9-pin DB-9 serial interfaces
• Confirm that your application specifically requires a null modem cross-wired pinout rather than a straight-through connection
• Evaluate whether the 3-meter length is appropriate for the physical layout of your equipment
• Assess if the 35-piece bulk pack quantity meets your installation or operational requirements

Usage recommendations: Handle the cable with care during installation to avoid sharp bends near the connector junctions. Store unused cables in a dry environment protected from moisture to maintain the integrity of the 28 AWG wiring and internal shielding.
