BlackBox KV0424A-R2 ServSwitch CX (1) analog, 4 users, 24 CPUs, max. resolution 1900 x 1440, range 50 m (max. 300 m), flash-update capable, On-Screen Menu content_copy

The ServSwitch CX (1) from BlackBox is an analogue KVM switch designed for central control of up to 24 computers by four users. The device enables management of multiple systems via a shared keyboard, monitor, and mouse, with a maximum resolution of 1900 x 1440 pixels. The range is up to 50 metres, while the maximum transmission distance is 300 metres. Control is performed via an on-screen menu displayed directly on the monitor, and the device is suitable for flash updates to install firmware changes or improvements later.

KVM-Switch
The ServSwitch CX (1) functions as a central interface between multiple computers and one or more user workstations. It allows switching between up to 24 connected computers using a single input device set — consisting of keyboard, mouse, and monitor. Support for four users means that four separate workstations can be connected to the device simultaneously, with each user having individual access to the connected systems. Analogue signal transmission ensures a direct, cable-based connection without digital encoding, making it particularly suitable for stable and lag-free control.

Applications
This device is designed for environments where multiple servers or workstations must be centrally managed, such as in data centres, IT departments, or during technical maintenance work. The ability to control up to 24 CPUs via a KVM switch makes it a solution for medium to large system landscapes. The maximum range of 300 metres allows flexible placement of connected devices, even over greater distances, with a maximum resolution of 1900 x 1440 pixels guaranteed at 50 metres distance. Typical use cases include server rooms or network equipment maintenance, as users can access all systems from a central point.

Functions and Equipment in Detail
The ServSwitch CX (1) features an on-screen menu that enables control and configuration of the device directly on the monitor. This menu is intended for navigating through various settings and selecting connected systems. The flash update capability allows updating the device’s firmware via an update procedure without requiring physical replacement or complex network installation. This is particularly useful for maintenance and adapting to new requirements or security standards.

Technology Explained Simply
Analogue signal transmission means that signals from keyboard, mouse, and monitor are transmitted unchanged over the cable without digital conversion. This results in low latency and high signal quality, especially over short distances. The maximum resolution of 1900 x 1440 pixels at a distance of 50 metres is sufficient for most applications, while a range of up to 300 metres is possible with reduced resolution or signal quality. Support for four users requires a corresponding number of input devices and monitors, each connected to the device.

Compatibility and Accessories
The ServSwitch CX (1) is designed for use with analogue KVM systems and does not require special protocols or digital interfaces. Compatibility with up to 24 computers makes it a scalable solution for larger systems. Standard KVM cables are required, with cable length and quality affecting range and signal quality.

Installation and Mounting
Installation involves connecting the computers to the appropriate ports on the ServSwitch CX (1). User workstations are connected via input devices (keyboard, mouse, monitor) to the device. Configuration is performed via the on-screen menu, visible on the connected monitors. Firmware updates can be carried out via the flash update procedure, with exact steps described in the user manual.

Operational Advantages
Central control of up to 24 computers by four users reduces the number of required input devices and monitors, making the workspace tidier and more organised. Analogue signal transmission ensures stable and lag-free control, which is especially important during system maintenance. The flash update capability enables easy maintenance and firmware adaptation without requiring the device to be removed or fully reconfigured. The maximum range of 300 metres offers flexibility in placing connected systems, with optimal signal quality maintained at shorter distances.
