InLine B-12210 Serial Extension Cable 9-pin, 10 m Length

InLine B-12210 is a 9-pin serial extension cable with a 10 m length designed to extend RS-232 connections between devices. The cable preserves the standard 9-pin DE-9 connector format to maintain compatibility with existing serial ports, allowing peripherals to be positioned further from host equipment without modifying interfaces. Its straightforward wired design supports basic serial communication needs in environments where a reliable physical connection is required.

Advantages

The extension cable offers a simple plug-and-play solution for extending RS-232 links while retaining the original connector format and signal wiring. At 10 meters, it provides increased installation flexibility for connecting modems, industrial controllers, POS terminals and other legacy serial hardware. The fixed-length construction reduces the need for custom cabling and helps maintain signal integrity over the extended run when used within standard serial communication distances.

Suitable for

• Extending RS-232 serial connections between computers and peripherals
• Connecting point-of-sale (POS) devices to host systems
• Linking industrial controllers, PLCs and serial sensors
• Extending connections for modems, label printers and barcode scanners
• Temporary or permanent installations requiring a reliable wired serial link

Key specifications

• Connector type: 9-pin DE-9 male to 9-pin DE-9 female connector configuration
• Cable length: 10 m
• Interface standard: RS-232 serial communication
• Wiring: standard 9-pin serial pinout preserving transmit, receive and ground lines
• Construction: shielded cable designed for reduced interference in typical environments

How to use

Plug the male end of the extension cable into the serial port of the host device and attach the female end to the peripheral's serial cable or device port. Ensure connectors are firmly seated and, if applicable, secure any thumbscrews to maintain a stable mechanical connection. Configure serial communication settings (baud rate, parity, data bits, stop bits, flow control) on both devices to match the peripheral requirements before initiating data transfer.

Recommendations

For reliable operation, use the cable within standard RS-232 distance limitations and avoid routing near strong electromagnetic sources or high-voltage power lines. If longer runs or higher noise immunity are required, consider alternative solutions such as signal repeaters, differential converters (e.g., RS-422/RS-485) or fiber-based extenders. Regularly inspect connectors for corrosion or damage and replace the cable if physical wear is observed.
