ACT 3 metre Serial 1:1 connection cable 25 pin D-sub male - 25 pin D-sub female

The ACT 3 metre Serial 1:1 connection cable provides a 25 pin D-sub male connector on one end and a 25 pin D-sub female connector on the other, delivering a straightforward 1:1 wiring configuration for serial communication. With a length of 3 metres and an ivory jacket, this cable is designed for connecting legacy parallel/serial equipment, industrial controllers, printers and other devices that use a standard 25-pin D-sub interface. The cable construction focuses on reliable signal continuity and straightforward installation where direct pin-to-pin mapping is required.

Advantages

This serial cable offers a full 25-pin D-sub male-to-female 1:1 connection, maintaining direct pin mapping for compatibility with equipment expecting standard wiring. The 3 metre length allows flexible placement between devices without the need for adapters or repeaters. Its neutral ivory colour and robust connectors support long-term use in office, laboratory or industrial settings while minimising visual distraction and cable clutter.

Suitable for

• Connecting legacy computers to parallel/serial peripheral devices
• Linking industrial controllers, PLCs and measurement instruments
• Printer interfaces that use a 25-pin D-sub connection
• Field service, testing and diagnostic setups requiring 1:1 pin mapping

Key specifications

• Connector A: 25-pin D-sub male
• Connector B: 25-pin D-sub female
• Cable length: 3 metres
• Wiring: 1:1 pin-to-pin configuration
• Colour: ivory
• Typical use: serial/parallel signal transmission between devices with 25-pin D-sub interfaces

How to use

Ensure both devices are powered off before connecting to avoid unintended signals. Align the male and female 25-pin D-sub connectors, gently insert the male into the female receptacle and secure any thumb screws or fastening hardware to prevent accidental disconnection. After fastening, power on the devices and verify communication settings such as baud rate, parity and handshaking on both ends if applicable. For removal, power down devices and loosen the connector screws before withdrawing the plug.

Recommendations

For reliable operation, route the cable away from high-voltage lines and sources of strong electromagnetic interference. Avoid sharp bends and excessive pulling force on the connectors; secure the cable near connection points if equipment will be moved. If long-term outdoors or high-moisture exposure is expected, consider additional environmental protection or a cable suited for those conditions.
