Figure 8- Connections grouped by port number

Please note: If the switches are being cascaded (such as that illustrated in Fig. 5 on page 5 under “Cascading”), make note of which port each of the CPUs is connected to on each slave and which port each slave is connected to on the master.

•The ports on the slave connected to the port 1 port on the master would be numbered 01-04 with multiple KEEMUX-P4s, the ports on the slave connected to port 2 would be numbered 05-08 (with multiple KEEMUX-P8s they would be 01-08, and 09-16, etc.)

•A connection to a CPU from the keyboard would be achieved by typing the appropriate port number. (See Fig. 6 on page 6.)

•No programming of the KEEMUX is necessary to achieve this control.

•When cascading, if not all of the ports are used on each slave attached to your system, THE PORT NUMBER(S) ASSOCIATED WITH THE UNUSED PORT(S) WILL NOT BE ACCESSIBLE when trying to control the switches connected to the system. (I.e. if ports 7 and 8 are not used on the first slave and an attempt is made to connect to ports 7 or 8 while in Command Mode, the KEEMUX will ignore the attempt. )

Scan Mode

When in Scan Mode the KEEMUX scans each port with a CPU powered-ON. (The SCAN LED on the front panel will illuminate and remain ON while in Scan Mode.) The port with the CPU powered-ON remains active while in use. When the switch becomes idle for the configured time-out period (default time-out period is 5 seconds) the switch will connect to the next powered-ON CPU port. See Command Mode section above for configuring the scan time-out period.

FYI: The keyboard and mouse must remain idle for the full scan time-out period before the switch will connect to the next active port.

Broadcast Mode

(Use with extreme caution or commands intended for one CPU will be sent to all CPUs)

Broadcast Mode allows the operator to send keystrokes to all active CPUs simultaneously. However, Broadcast Mode has some critical requirements.

•BROADCAST LED must be OFF when booting any attached CPUs.

•BROADCAST LED must be ON and COMMAND LED must be OFF for keystrokes to reach attached CPUs.

Note: The user must type somewhat slowly when in Broadcast Mode (less than 20 wpm) and cannot use the <Backspace> key.

Normal Mode

When all of the KEEMUX mode LEDs are OFF the user is in Normal Mode, controlling the CPU to which the user is connected through the KEEMUX.

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.
