Serial cable DeLOCK 87837 1.8m DB9 male to DB9 male

The DeLOCK 87837 serial cable is a 1.8 metre DB9 male to DB9 male cable designed for reliable point-to-point serial communication. It connects devices that use standard 9-pin RS-232 ports, supporting stable data transfer between computers, industrial controllers, printers and other serial peripherals. The cable features conventional DB9 male housings on both ends and a flexible jacket suitable for office, workshop or equipment-rack installations.

Advantages

This DB9 male to DB9 male cable provides a straightforward, durable connection for serial devices. Its 1.8 m length offers a balance between reach and signal integrity for typical desktop and equipment-rack layouts. The compatible 9-pin connectors ensure simple plug-and-play operation with devices that implement standard RS-232 signaling. The cable construction aims to minimise signal loss and mechanical wear during repeated connection cycles.

Suitable for

• Connecting desktop PCs to serial printers and modems
• Linking industrial controllers and PLCs with monitoring equipment
• Establishing serial communication between measuring instruments and data loggers
• Connecting legacy hardware with DB9 serial ports to modern systems or converters

Key specifications

• Cable length: 1.8 m
• Connector type: DB9 male to DB9 male (9-pin)
• Interface standard: RS-232 compatible
• Cable jacket: flexible insulated sheath suitable for indoor use
• Typical applications: serial data transfer, device configuration and diagnostics

How to use

Connect one DB9 male connector to the serial port of the first device and the other DB9 male connector to the second device. Ensure both devices are powered off before connecting to prevent signal or hardware issues, then power them on and select the appropriate serial settings (baud rate, parity, data bits, stop bits, flow control) in the communicating applications or device firmware. If needed, verify pinout compatibility and signal direction for particular hardware configurations.

Recommendations

For optimal performance, route the cable away from sources of strong electromagnetic interference such as large motors, high-current power lines or unshielded network cables. Avoid tight bends and excessive pulling; secure the cable with gentle fasteners and allow some slack for device movement. Use dedicated RS-232 ports or suitable converters when adapting to USB or other interface types.
