(Abbr. for console) The user console (CON module) receives the KVM information at the console. Learn more >>

The controller card manages the system’s central administration, monitoring and control. Learn more >>

(Abbr. for Central Processing Unit); Computer connection module, which taps the computer’s KVM signals and transmits them to the matrix switch. Learn more >>

CrossDisplay-Switching makes it easy to switch between computers using the mouse (TradeSwitch function required).

A screen switch or display switch is a device that makes it possible to connect several video sources to one or more screens. However, it differs from a KVM switch in terms of functionality and scope. Learn more >>

A DisplayPort switch enables multiple video sources to be connected to a monitor with a DisplayPort connection.

A monitor’s EDID information (Extended Display Information Data) inform the graphics card of a connected computer about the monitor’s various technical features.

An HDMI KVM extender is a special device that makes it possible to transmit HDMI video and KVM signals (keyboard, video, mouse) over greater distances than with conventional cabling. Learn more >>

HID stands for "Human Interface Device" and refers to input devices such as keyboards, mice, joysticks, game pads, trackballs, touchpads or touchscreens that are used to enable human interaction with computers or other electronic devices. HID is a standard for communication between input devices and computers or other devices.

The KVM Matrix-Grid™ enables bidirectional communication between digital KVM matrix switches. It is ideal for applications where bidirectional access between two or more matrix central units is required. Learn more >>

The KVM network switch is similar in function to a KVM matrix system, but is not the same; it does offer some network functions, but does not have the extended scalability and multi-user functions of a fully-fledged KVM matrix. Learn more >>

A KVM-over-IP switch is a state-of-the-art device that allows users to remotely control multiple computers or servers over an IP network. Since a KVM-over-IP matrix offers the same functions, the term "KVM-over-IP switch" is often only used as a synonym. Learn more >>

KVM switches are often the basis for building redundant systems in different control room applications.
Operate multiple computers with only one mouse, one keyboard and up to four screens and make your workplace more efficient and ergonomic. Switching between computers is done via buttons on the front panel, configurable key combinations or a serial device.

Multi-channel modules are used to implement multi-video computers or multi-monitor workplaces.

Mirror mode refers to the ability to display the same video content simultaneously on multiple output devices, such as monitors or video walls. Learn more >>

By definition, Modbus is a communication protocol that was developed by Gould-Modicon in 1979. It enables simple, reliable and fast data transmission between automation and field devices. Learn more >>

The push-get function optimizes collaboration in the control room and allows users to "push" the image on their monitor to the display of another workplace or a large-screen projection, or to "get" it from there. This solution also improves communication, flexibility and speed within the team, as employees can now complete tasks together.

IP-Control-API enables the external control of a matrix switch (e.g. switching over a TCP/IP connection). Learn more >>

Remote KVM is a technology that allows users to control one or more computers or servers remotely as if they were physically on site. Normally, this remote control is done via a network that uses the Internet. KVM-over-IP matrix systems, for example, are used to deploy remote KVM extensively. Learn more >>

The Real Time Streaming Protocol (RTSP) is a network control protocol that is used to control the data transfer of video and audio files in real time between server and client. It enables the playback of media-based content without having to download it completely. Learn more >>

Scenario switching lets you store the switching condition of one or multiple workplaces or even of the entire system. The selected switching states are saved in a script in the matrix system and can be accessed and executed via the OSD of workplaces assigned with the required rights. Learn more >>

Simple Network Management Protocol. Devices with SNMP support offer extensive possibilities to set up automatisms and active alarm notifications. Tools for SNMP management offer options for issuing critical system statuses as alarms via e-mail or SMS.  Learn more >>

Switching ON and OFF or „moving“ a switching component the CPU modules remain unaffected preventing the „freezing“ of computers whilst connection is inactive.
Learn more >>

The switch card is the central unit containing the switching logic of the matrix switch. Learn more >>

Syslog (System Logging Protocol) is a proven protocol for transmitting log data within a network. It supports the centralized management of event logs generated by various network devices such as servers, firewalls and routers. Learn more >>

A TCP (Transmission Control Protocol) connection is a connection between two endpoints in a computer network based on the TCP protocol. Unlike the UDP connection, TCP uses a three-way handshake mechanism to establish a connection between the endpoints before data is transmitted. This mechanism ensures that both endpoints are ready to send and receive data before the transmission begins.

During data transmission, TCP constantly monitors the connection and detects and corrects errors such as lost data packets or congestion. TCP ensures that all data packets are received in the correct order and, if necessary, requests missing packets to ensure that all data is received in full. Learn more >>

TCP is a reliable transport layer protocol of the Internet Protocol (IP) and ensures that data is transferred between endpoints reliably and in the correct order. Learn more >>

TLS (Transport Layer Security) is a cryptographic protocol that enables secure communication over a computer network. It is often used to ensure the privacy and integrity of data between communication partners, for example with HTTPS connections on the Internet. Transport Layer Security is the successor to SSL (Secure Sockets Layer) and offers improved security mechanisms. Learn more >>

The TradeSwitch function operates multiple computers via one keyboard and mouse. The TradeSwitch function includes CrossDisplay-Switching. Learn more >>

UDP (User Datagram Protocol) is a communication protocol of the Internet Protocol (IP) and is often used in IT communication. Unlike TCP (Transmission Control Protocol), UDP provides a non-reliable, connectionless link. A UDP connection allows a sender to send datagrams to a receiver without first establishing a connection or verifying that the receiver is ready to receive data. This connection is not reliable because data can be sent without confirmation or retransmission, which means that some data packets may be lost or arrive in the wrong order. Learn more >>

Unicast is a network communication method in which a single source sends data to a single destination address. In this process, a data packet is sent from the source to a specific IP address and received by a single receiving device. Unicast is often used when direct and private communication between two devices is required, such as when transmitting email or retrieving web pages. Learn more >>
