The InLine B-12222 serial null modem cable is a reliable solution designed for establishing secure point-to-point communication between legacy serial devices and computer peripherals. Spanning a length of 2 meters, this cable features a neutral beige colour and an outer cable diameter of 5.4 mm, ensuring it blends discreetly into professional and industrial environments. Equipped with DB-9 female connectors on both ends, it facilitates direct data transmission without requiring complex configuration. The connectors are encapsulated with knurl-thumb screws for secure attachment and stable operation during continuous use.

Advantages

This serial null modem cable provides dependable data transmission for equipment that relies on standard serial interfaces. The durable construction and quality shielding help maintain signal integrity over the 2-meter distance. Featuring standardized DB-9 female connections on each end, the cable ensures broad compatibility with various older hardware systems, industrial machinery, and networking peripherals. The inclusion of knurl-thumb screws allows for manual tightening without tools, ensuring the connections remain firmly in place even in vibration-prone settings.

Suitable for

• Connecting legacy serial devices and computer peripherals
• Point-to-point data communication in industrial setups
• Direct installation and maintenance work at customer sites

This cable may not be suitable for modern computers and devices that lack traditional 9-pin serial ports, as it requires appropriate adapters for newer USB-only interfaces. It is also not designed for high-speed network data transfers typical of Ethernet cables.

Key specifications

• Cable length: 2 m
• Connector 1: DB-9 female
• Connector 2: DB-9 female
• Cable diameter: 5.4 mm
• Wire size: 28 AWG
• Colour: Beige

To use the serial null modem cable, ensure that both connected devices are powered off before plugging the cable into the respective DB-9 serial ports. Secure the connections on both ends by tightening the integrated knurl-thumb screws manually to prevent accidental disconnection. Once the physical connection is secured, power on the devices and configure the communication parameters within your operating system or control software.

What to consider before purchase

• Verify that both of your devices feature standard 9-pin DB-9 serial ports
• Confirm that a 2-meter cable length is sufficient for your setup distance
• Ensure your application requires a null modem crossover pin configuration rather than a straight-through cable

Usage recommendations: Handle the cable with care by gripping the connector housings rather than pulling directly on the wire when disconnecting. Store the cable in a dry environment away from excessive heat and sharp bends to maintain optimal performance and longevity.
