CHAPTER 5: Operation

5.4 Things to Keep in Mind About the Keyboards and Mice

PC bootup sequence: When your PC CPUs are powered on, they communicate with any attached keyboards and mice and load the setup parameters required by their particular operating systems. It is necessary for the Extender to be attached and powered on during this sequence so that it can give the CPUs the required responses and keep track of all the modes and settings requested by each of the connected CPUs.

Mouse characteristics: Do not unplug a PS/2 mouse connection from a CPU while the CPU is on. Because of the way PS/2 mice communicate, the CPU will lose mouse function and you will have to reboot the CPU to regain normal operation. Unplugging a shared PS/2 mouse from the Extender will have no immediate effect, but the PC will lose mouse function as soon as you plug the mouse back in. (RS-232 mice can usually be freely unplugged and replugged, provided that an RS-232 mouse was connected when the operating system initially booted.) The Extender has a PS/2 mouse-recovery system which allows you to disconnect and reconnect the mouse without powering down the system, but we recommend using this only when absolutely necessary. See Section 5.6 for details.

Keyboard- and mouse-mode handling during CPU switching: The Extender keeps a log of the keyboard and mouse modes and resolution settings requested by each of the connected CPUs, including the keyboard Num Lock, Caps Lock, and Scroll Lock states. These settings are automatically restored to the primary keyboard and mouse when you switch to the other CPU, as well as when the Extender is returned from configuration, password-lockout, or control-lockout mode to normal operation, ensuring maximum software compatibility.

This makes them ideal for installations where the source and display devices cannot be placed in close proximity. The units support a wide range of resolutions, accommodating 1080p, 4K, and even 3D video formats, ensuring that users can achieve top-tier visual quality.

In terms of connectivity, the ACU5011A and ACU5010A offer multiple input and output options, including HDMI and VGA ports, to accommodate various av devices. The ACU5011A model specializes in HDMI, while the ACU5010A emphasizes VGA connectivity. This flexibility allows users to connect different types of devices seamlessly, promoting versatility in different applications.

Both models incorporate advanced signal compression and balancing technologies, reducing the risk of signal degradation and maintaining the integrity of audio and video signals over long distances. Furthermore, they feature built-in equalization and hot plug detection, ensuring that the signals are automatically optimized for the highest quality output upon connection.

Another notable characteristic of the ACU5011A and ACU5010A is their ease of installation and user-friendly design. They come with clear indicators for power and signal status, allowing users to troubleshoot issues quickly and efficiently. Additionally, the compact form factor allows for easy integration into existing systems without the need for extensive modifications.

In summary, the Black Box ACU5011A and ACU5010A represent cutting-edge solutions for audio and video signal management. Their longevity of signal transmission, solid compatibility with multiple devices, and sophisticated signal processing capabilities make them excellent choices for high-demand environments. With their focus on quality, reliability, and ease of use, these models stand out as top contenders in the field of AV distribution technology.
