Serial Cable Deltaco DEL-34 Grey 3 m DB9 DB25

The Deltaco DEL-34 Grey 3 m DB9 DB25 is a serial cable designed for reliable RS-232 connections between devices with DB9 and DB25 ports. With a 3 metre length and a neutral grey jacket, the cable offers flexible placement options while maintaining a discreet appearance in office or industrial environments. The construction focuses on consistent signal transfer for serial communication over short to medium distances.

Advantages

The cable provides a direct wired connection between DB9 and DB25 serial interfaces, reducing latency and interference compared with wireless alternatives. Its 3 m length balances reach and signal integrity for typical desk-to-equipment setups. The grey outer jacket resists everyday wear and integrates well into mixed-cable installations. Connectors are configured to match standard serial pinouts for straightforward compatibility with legacy and current equipment that use RS-232 signalling.

Suitable for

• Connecting serial printers, modems or barcode scanners to control systems
• Linking computers and industrial equipment with DB9/DB25 ports
• Field service and maintenance tasks requiring a durable serial link
• Laboratory or testing setups where predictable RS-232 communication is needed

Key specifications

• Cable length: 3 metres
• Connector types: one DB9 male/female to one DB25 male/female configuration as required for standard serial connections
• Color: grey outer jacket
• Purpose: RS-232 serial data transmission
• Construction: shielded conductors to support stable signal transfer (typical for serial cables)

How to use

Identify the DB9 and DB25 ports on the devices to be connected and ensure both devices are powered off before insertion to prevent potential signal issues during hot-plugging. Align the connector pins with the corresponding port and tighten the thumbscrews or retaining screws to secure the connection. After both ends are connected, power on the devices and verify the serial communication settings such as baud rate, parity and stop bits in the device software or terminal application to match the communicating endpoints.

Usage recommendations

For reliable performance, avoid sharp bends and excessive tension along the cable. Route the cable away from high-voltage power lines or sources of electromagnetic interference where possible. Periodically inspect connector contacts for corrosion or deformation and replace the cable if physical damage or recurring connection errors are observed.
