## Summary description

InLine B-12224 is a 3 m null-modem serial cable with 9-pin female connectors on both ends for direct RS-232 device-to-device communication. Designed to cross transmit and receive lines, it enables data exchange between computers, industrial equipment, legacy peripherals and serial consoles. Useful for configuration, diagnostics and low-speed data transfer.

## Long description

InLine B-12224 is a 3 m null-modem serial cable with 9-pin female connectors on both ends, designed for direct RS-232 device-to-device communication. The cable crosses transmit and receive lines to allow two DTE devices to exchange data without a modem or other intermediary. It is intended for configuration, diagnostics and low-speed data transfer between computers, industrial controllers, legacy peripherals and serial consoles.
Advantages
This null-modem cable provides simple, reliable wiring for RS-232 connections between two devices with DB9 female ports. The 3 m length offers flexibility to connect equipment across racks or workbenches while keeping signal attenuation low. The fixed crossover wiring eliminates the need to reconfigure ports or use adapters, and the standard 9-pin female connectors ensure compatibility with a wide range of legacy and industrial hardware.
Suitable for
 Connecting two PCs or laptops with serial ports for direct communication
 Linking industrial controllers and PLCs for configuration and diagnostics
 Interfacing with serial consoles on routers, switches and network devices
 Connecting legacy peripherals such as serial printers, modems or instrumentation
 Laboratory and workshop environments requiring simple RS-232 data exchange
Key specifications
 Cable type: null-modem (crossover) serial cable
 Connector type: 9-pin female (DB9) on both ends
 Length: 3 metres
 Signal standard: RS-232
 Wiring: transmit and receive lines crossed for DTE-to-DTE communication
 Shielding: braided or foil shield (manufacturer standard)
How to use
Plug each 9-pin female connector into the corresponding male serial port of the two devices you want to connect. Ensure both devices are powered off or their serial ports are inactive during connection to avoid unintended signals. Configure serial port parameters (baud rate, parity, data bits, stop bits and flow control) on both devices to match prior to data exchange. Use terminal software or device-specific configuration tools to perform diagnostics, transfer data or adjust settings over the RS-232 link.
Usage recommendations
Position the cable away from heavy electrical interference sources such as large motors or mains transformers to reduce noise. For longer-term installations in industrial settings, verify connector retention and consider strain relief to avoid mechanical stress. If higher data rates or longer distances are required, evaluate alternative interfaces or signal repeaters.
