NTI KEEMUX Series PS/2 KVM Switch

Keyboard Control

Keyboard control of the KEEMUX can be achieved using either of two methods:

Basic Command Mode- operated strictly by using keyboard commands as instructed below. Basic Command Mode is only applicable if the OSD option is not built into the switch.

OSD Command Mode (optional)- operated using the keyboard and mouse in conjunction with On Screen Display (OSD) menus superimposed onto the monitor. If OSD is built in, use the menus as instructed on page 12.

By pressing <Ctrl> + <`> (accent key), the user can enter Command Mode (either Basic, or OSD). Once in Command Mode, typing a series of commands will cause the KEEMUX to connect the user to any one CPU to which the KEEMUX is attached. Once finished, pressing the <Esc> key will exit Command Mode.

Basic Command Mode

In order to control the KEEMUX with the keyboard, Command Mode must be enabled. To enter Command Mode from the

keyboard:

NOTE: IF THE OSD FEATURE HAS BEEN INSTALLED, PROCEED DIRECTLY TO “OSD CONTROL” ON PAGE 10. If not, continue with the instructions for controlling the KEEMUX as detailed below.

When the COMMAND LED is illuminated, all 3 status lights on the keyboard will illuminate to indicate that Command Mode is enabled and the following functions are available: (NOTE: The user must exit Command Mode in order to type to a CPU. To exit Command Mode, press <Esc>.)

PS/2 KVM specifications

Network Technologies PS/2 KVM switches are essential devices that enable users to control multiple computers from a single set of keyboard, video, and mouse (KVM) peripherals. These devices are particularly advantageous in server rooms, data centers, and environments where space-saving is crucial, as they streamline the management and minimize the clutter of multiple keyboards and monitors.

A key feature of PS/2 KVM switches is their compatibility with the PS/2 interface, which has been a standard for connecting keyboards and mice for many years. This ensures reliable communication and seamless performance when managing various systems. The switch typically supports a wide range of resolutions, allowing users to connect to different video outputs without sacrificing image quality. Most PS/2 KVM setups can handle resolutions up to 1920x1200, making them suitable for high-definition applications.

One of the primary technologies utilized in PS/2 KVM switches is multi-platform support. This allows users to connect and control computers running different operating systems simultaneously, including Windows, Linux, and UNIX. This versatility is essential in environments with varied system requirements and contributes to improved operational efficiency.

In terms of scalability, many PS/2 KVM switches support daisy chaining and cascading, enabling the connection of multiple switches for managing even larger numbers of servers. This is particularly helpful for administrators who need to manage extensive infrastructures without the hassle of additional hardware.

PS/2 KVM switches also come with features such as hotkey switching, which allows users to switch between computers using keyboard shortcuts. This functionality enhances workflow efficiency, as users can quickly access different systems without the need for manual intervention. Additionally, they often include LED indicators that simplify status monitoring, ensuring users are aware of which systems are currently active.

Security is another critical aspect. Many PS/2 KVM switches offer the option to implement password protection and encryption protocols, safeguarding sensitive data during operations.

In summary, Network Technologies PS/2 KVM switches provide a robust and effective solution for managing multiple computers in various settings. Their combination of compatibility, resolution support, scalability, and security features makes them a valuable asset for IT professionals looking to enhance productivity and streamline operations.
