Serial cable DELOCK 84391 D-Sub 25 pin, beige, 3 m

DELOCK 84391 is a 3 m serial cable with 25‑pin D‑Sub connectors on both ends, supplied in beige. It is designed for RS‑232 and other legacy serial interfaces that use a full 25‑pin D‑Sub connector. The cable provides a direct wired connection for data transfer, device communication and configuration between computers, industrial equipment, instrumentation and peripherals that require a DB‑25 interface.

Advantages

The cable offers reliable point‑to‑point serial communication over a three‑meter length, making it suitable for typical desk‑to‑equipment or rack‑to‑device connections. With standardized 25‑pin D‑Sub connectors on each end it ensures compatibility with equipment that requires the full set of signals carried by a DB‑25 interface. The beige jacket and molded connector shells provide a conventional appearance and easy visual matching in mixed cabling environments.

Suitable for

• Connecting computers or terminals to serial printers and modems
• Linking industrial controllers, PLCs or measurement instruments to host systems
• Device configuration, firmware updates and direct serial console access
• Legacy equipment interfacing in laboratory or factory environments

Key specifications

• Cable length: 3 m
• Connector type: 25‑pin D‑Sub (DB‑25) male/female or as specified by device mating
• Purpose: RS‑232 and other 25‑pin serial interfaces
• Colour: beige jacket and connector housings
• Cable usage: point‑to‑point serial data and control signal transmission

How to use

Identify the DB‑25 serial ports on the devices to be connected and align the 25‑pin D‑Sub connector orientation with the port. Insert the connectors fully and secure any retaining screws or fasteners to ensure a stable mechanical and electrical connection. Use the cable to transmit RS‑232 serial signals for communication, configuration or data transfer; verify serial settings (baud rate, parity, stop bits, handshake) on both ends prior to operation.

Recommendations

For reliable communication, avoid routing the cable near high‑power or high‑frequency sources that may introduce interference. Use the 3 m length for typical equipment-to-equipment connections; for longer runs consider using appropriate repeaters or alternative interfaces. Inspect connector pins and housings for damage before use and tighten connector screws to prevent intermittent connections.
