The extension cable from BlackBox enables the extension of existing parallel or serial connections over a length of up to 7.6 metres. It is specifically designed for use in IT and electronics environments where stable and reliable data transmission over longer distances is required. The cable features a DB25 plug at one end and a DB25 socket at the other, with a 1:1 pin assignment to ensure signal integrity. The construction with fully potted connectors provides high mechanical stability and improves the cable's longevity. The connectors are equipped with knurled screws, which allow for a secure and firm connection with the connected devices.

Applications
This cable is suitable for use in environments where parallel or serial interfaces are used, for example with older printers, industrial controls, or legacy systems. The maximum length of 7.6 metres provides sufficient flexibility to connect devices that are spatially separated, without requiring additional amplifiers or converters. Use in offices, workshops, or industrial facilities is possible, provided the environmental conditions meet the requirements for mechanical strength and signal quality.

Functions and Features in Detail
The connectors are fully potted, providing high mechanical stability and protection against mechanical stress. The knurled screws on the connectors allow for manual, precise locking, preventing accidental disconnection or loosening of the connection. The 1:1 pin assignment ensures that each signal is transmitted directly, without rerouting or conversion, which is essential for compatibility with existing systems. The cable is shielded to minimise electromagnetic interference and maintain signal quality over the entire length.

Technology Explained Simply
The shielding of the cable protects the internal conductors from external electromagnetic influences that could cause signal interference or data loss. The fully potted connectors prevent contact displacement and increase the cable's lifespan. The knurled screws provide a mechanical lock, which is particularly useful in environments with vibrations or movement. The 1:1 pin assignment means signals are transmitted directly from one device to another, without requiring additional logic or conversion.

Compatibility and Accessories
The cable is designed for parallel and serial interfaces that use the DB25 connector set. It is compatible with devices featuring a DB25 plug or socket, such as older printers, terminal devices, or industrial controls. It can be used as a direct replacement for shorter extension cables or to extend existing connections. No additional accessories or adapters are required, as the connection is made directly via the DB25 interface.

Installation and Mounting
Installation is performed by simply inserting the plug into the corresponding socket and then tightening the knurled screws to ensure a secure connection. The cable connection should be positioned to avoid mechanical stress or bending strain on the connectors. The maximum length of 7.6 metres requires careful planning of the cabling to ensure signal quality is not compromised. No special tools or additional components are required for installation.

Operational Advantages
The cable provides a reliable and stable connection over a length of up to 7.6 metres, increasing flexibility in device placement. The knurled screws ensure a secure connection that remains intact even under mechanical stress. The shielding protects signals from interference, which is particularly important in environments with high electromagnetic noise. The fully potted connectors increase lifespan and reduce the risk of contact issues due to wear or contamination.
