Serial Cable ALLNET ALL4500_COM Black DB-9 Male

The ALLNET ALL4500_COM Black DB-9 Male serial cable is a compact, lightweight connection cable designed for reliable serial data transmission between devices with DB-9 serial ports. With a slim profile and straightforward single-piece design, it provides a stable physical link for configuration, diagnostics, and communication tasks where a standard 9-pin D-sub male interface is required.

Advantages

This serial cable offers consistent signal transfer with minimal interference thanks to its shielded construction and precise DB-9 male connector. At approximately 20 g, it is easy to handle and transport, and the robust connector housing ensures a secure fit and long service life. The single-piece package simplifies procurement and inventory management for small-scale installations and field service kits.

Suitable for

• Connecting legacy industrial equipment and controllers to laptops or terminals
• Serial console access to networking devices, routers and switches
• Configuring embedded systems, PLCs and instrumentation with DB-9 ports
• Field diagnostics, maintenance tasks and firmware updates via RS-232 interfaces

Key specifications

• Connector type: DB-9 (9-pin) male
• Color: Black
• Weight: approximately 20 g
• Configuration: single-piece cable, ready for direct serial connection
• Intended interface: standard RS-232 serial communication

How to use

Insert the DB-9 male connector firmly into the corresponding DB-9 female port on the target device or adapter until the connector seats securely. If the device includes thumbscrews or retention hardware, fasten them to prevent accidental disconnection. Use standard serial communication settings on your host equipment (baud rate, parity, data bits, stop bits) according to the target device’s documentation. After use, disconnect by loosening any retention screws and gently withdrawing the connector.

Recommendations

Use the cable within typical indoor operating conditions and avoid sharp bends or strain on the connector. For long-term installations or in electrically noisy environments, verify grounding and consider additional shielding or ferrite cores to maintain signal integrity. Store the cable coiled without kinks to preserve connector and cable life.
