Serial Cable ShiverPeaks BS78065-3 Grey 3m DB-9 DB-25

The ShiverPeaks BS78065-3 Grey 3m DB-9 DB-25 is a 3-metre serial cable designed to provide stable, point-to-point data connections between devices with RS‑232 style ports. One end terminates in a DB-9 male/female connector and the other in a DB-25 connector to support equipment that uses either 9-pin or 25-pin serial interfaces. The cable jacket is grey and the 3 m length offers flexible placement while maintaining signal integrity for typical serial communication distances.

Advantages

This serial cable offers a straightforward, low-latency connection for legacy and industrial equipment that rely on DB‑9 and DB‑25 serial ports. The fixed 3 m length balances reach and manageability, reducing the need for extenders while keeping cable routing tidy. Constructed for reliable electrical contact, it supports common serial setups without additional adapters when connecting mixed-port systems.

Suitable for

• Connecting older PCs, terminals or modems with DB‑9 to peripheral equipment using DB‑25
• Industrial controllers, CNC machines and measurement instruments with serial interfaces
• Point‑to‑point configuration and diagnostic connections in workshops and labs
• Legacy POS systems, printers or networking gear requiring direct serial links

Key specifications

• Cable length: 3 metres
• Connector types: DB‑9 on one end and DB‑25 on the other
• Colour: grey outer jacket
• Signal type: RS‑232 serial signalling compatible
• Cable construction: multi‑core shielded conductor (typical for serial use)

How to use

Identify the serial ports on both devices and match the DB‑9 and DB‑25 connectors to the corresponding ports. Align pins carefully and secure connectors using the thumbscrews or fastening hardware if present to ensure a stable mechanical connection. Configure serial communication parameters (baud rate, parity, data bits, stop bits and flow control) on both devices so they match, then test the link with a terminal program or device diagnostics. If communication issues occur, verify pinout compatibility and cable orientation, and check for loose fastening or bent pins.

Usage recommendations

For best results, avoid running the cable alongside high-voltage power lines or heavy machinery that can introduce electromagnetic interference. Use short, supported runs and strain relief at connection points; inspect connectors for bent pins before each use. When integrating with industrial equipment, confirm signal and grounding requirements to prevent damage to connected devices.
