    Chapter 2: Overview 2. Overview 2.1 Introduction There are four versions of the four-way ServSwitch Wizard™ VGA (USB), each of which allows a single operator to control up to four computer systems and share peripherals among them in a very flexible manner. The KV3004A can support one video head per channel, whereas the slightly larger KV3204A, KV3304A and KV3404A units support two, three and four video heads per channel, respectively. In addition to impressive VGA video performance, these units offer more than just straight switching between four systems. The KVM, speakers and two separate USB devices attached to the ServSwitch Wizard VGA (USB) units can either be switched in uni- son, as normal, or you can mix your peripherals between any of the systems to suit your current tasks. For instance, you could be creating emails on one system, listening to a soundtrack from another while a third is sending documents to your printer and a fourth performing another task with a different USB peripheral. The ServSwitch Wizard VGA (USB) front panels make it straight- forward to control which peripherals should connect to each system. The ServSwitch Wizard VGA (USB) units feature True Emulation (see Appendix A for more details) which ensures that the full characteristics of the connected keyboard and mouse are passed to every system. Multiple switching Multiscreen versions The attached peripheral devices can be switched The ServSwitch Wizard VGA collectively to any computer (USB) range system, or can be linked to includes separate separate systems to achieve models to multiple tasks in parallel. Multiple switching can be support one, two, three or controlled from the on- screen menu or using the four video heads per channel.

    ServSwitch Wizard VGA (USB) 2.2 Features Multiscreen Versions The ServSwitch Wizard VGA (USB) includes separate models to support one, two, three, or four video heads per channel. Multiple Switching The attached peripheral devices can be switched collectively to any computer system, or they can be linked to separate systems to achieve multiple tasks in parallel. Multiple switching can be controlled from the on-screen menu or using the front-panel buttons. Analog Video The ServSwitch Wizard VGA (USB) uses VGA connectors throughout for full compatibility with legacy analog systems. True Emulation Earlier USB KVM switches relied upon standard keyboard and mouse templates to tell each computer system how to deal with the connected peripherals. The ServSwitch Wizard VGA (USB) range gathers the true identities of the connected keyboard and mouse and presents those “real” profiles concurrently to every system. Thus, specialized keyboards and mice can be fully support- Intelligent Display Information The ServSwitch Wizard VGA (USB) uses an EDID emulation feature to ensure that all computers are supplied with the correct information about each connected video display. USB Remote Wakeup The ServSwitch Wizard VGA (USB) fully supports the USB Remote Wakeup feature. Any connected computer can go into sleep mode and be awakened (when its channel is selected) as soon as you press a key or move the mouse. Note that the computer and peripherals must also support the USB Remote Wakeup feature. 2.3 What‘s Included Your package should include the following items.

  • Page 21: Synchronizing Multiple Units

    Chapter 3: Installation 3.2.5 Synchronizing multiple units ServSwitch Wizard VGA (USB) units can be connected together so that they operate in a synchronized manner. Thus, two KV3004A units can be made to switch two video heads in a similar manner to an KV3204A. Additionally, two KV3204A units could be made to resemble an KV3404A, while two KV3404A units could be combined in order to switch up to eight video heads simultaneously. Whenever an ServSwitch Wizard VGA (USB) channel is switched, it sends an RS232 command out on its serial interface (marked on the rear panel). A ServSwitch Wizard VGA (USB) unit will switch its channel if it receives the same command on its OPTIONS serial interface. Consequently, by linking the serial interfaces, a master unit may be made to automatically switch one or more slave units as shown in Figure 3-15. It should be noted that the synchronization cable deliberately does not have the transmit pin of the Slave End connector linked to the receive pin of the Master End connector. To do so would cause the Slave unit to be able to switch the Master unit. This would setup an endless cyclical switching sequence that would prevent the ServSwitch Wizard VGA (USB) devices from operating cor- rectly.

    Chapter 5: Operation 5.1.2 Selecting a computer using hotkeys Using hotkey combinations, you can quickly switch the keyboard, video monitor(s), mouse and speakers and USB peripherals to any computer channel. There are two mains ways to use hotkeys: Standard and Additional. To use standard hotkey press combinations The standard hotkey press combinations allow you to change channels with the minimum of keypresses: 1 Simultaneously press and hold CTRL and ALT (or other hotkeys, if altered). 2 While still holding CTRL and ALT, press the number key of the required channel address (or the TAB key), then release all of the keys. Note: The numbers on your keyboard’s numeric keypad are not valid, use only the numeral keys above the QWERTY section. The ports (KVM, audio and/or USB) that are switched using this method depend upon the switching mode that is currently set using the front panel buttons.

The password is not case sensitive and can be any combination of key strokes, including the function keys, but excluding the Num Lock, Caps Lock, Scroll Lock and Enter keys. If your keyboard has special media keys, these also cannot be used as part of the password. When you have typed in your password, press Enter to store it. Don’t worry if you type the password incorrectly, you can always re-enter configure mode and set the password again.

  • Page 34: Autoscanning

    ServSwitch Wizard VGA (USB) 5.3 Autoscanning When enabled, the autoscan mode switches between the connected computers in sequence. This is useful to allow you to sample activity among the connected computers. Two scanning modes are available: • Cycle all ports – This mode visits, in turn, to each connected computer. This mode should be used with care due to the reasons given in the warning below. To prepare for this autoscan mode, choose U 7 within the configuration menu. • Cycle only active ports – Only computer ports where an active computer is detected will be viewed. This mode avoids blank screens from being displayed and helps to prevent the viewing monitor from entering a power-down state on every scan cycle. Additionally, when this mode is selected, whenever you use either the mouse buttons or hot keys + tab to change channels, only computers that are active will be visited. To prepare for this autoscan mode, choose U 8 within the configuration menu. WARNING: Many monitors are fitted with automatic power saving relays that switch off after a few seconds when connected to an inactive computer.
  • Page 35 Chapter 5: Operation To start autoscanning • On the keyboard, press CTRL ALT X. Notes: During autoscanning, mouse switching, hot key + tab and interactivity with the computers are all disabled. During autoscanning, only the KVM and speaker ports are switched to each visited computer channel, the two USB device ports remain connected to their currently selected channels.

  • Page 36: Appendix A. What Is True Emulation

    ServSwitch Wizard VGA (USB) Appendix A. What is True Emulation? True Emulation represents a significant breakthrough in sharing USB devices between two or more computer systems. Until this point, the problem has been how to create a USB switch that provides all of the following: • Quick, transparent and reliable switching, • Accurate representation of the connected USB keyboard and mouse, • Switching control via the connected USB keyboard and/or mouse. The difficulty in achieving all of the above requirements has been due to the complexity of the USB standard. This has led to vari- ous problems that have spawned a number of possible solutions. A.1 Enumerated USB switching The earliest attempts to switch USB devices applied a relatively ‘hands off’ approach. Enumerated USB switches are the electronic equivalent of those old mechanical KVM switches with a large knob on the front. Enumerated switches are so called because a connected USB device will be required to perform a full initiation (a process called Enumeration) every time it is switched; just as if you had pulled out the plug and then reconnected it. Enumerated switches simply pass all signals straight through between the USB device and the computer, they do not attempt to interpret any data. For most devices, this offers an advantage because the switch just leaves them to get on with their jobs with- out any interference or any hit on performance. However, it means that a USB keyboard or mouse cannot be used to control the switching process - a quick and simple control method expected by most users. Reliability of switching is also an issue that has plagued enumerated switches, especially when used with certain USB devices and particular operating systems. A.2 Emulated USB switching The issues with interpreting the complex USB data streams and recreating (or Emulating) the identity of attached USB devices were eventually solved, leading to the creation of the Emulated USB switch. A neat side effect of the technique used is that each computer can be fooled into thinking that the USB device is permanently connected to it, even when the device is switched to another computer. This means that the enumeration process for the USB device takes place only once, during the first power on. After that, a computer merely sees a dormant version of the USB device whenever the device is actually connected to a different computer.
  • Page 37 Appendices True Emulation is not necessarily required by other USB devices, which is why you will also find two enumerated circuits included (shown in green within the block diagram) alongside the True Emulation feature (shown in blue). This allows those other USB devices to operate at their highest speeds, without any intervention. The enumerated circuits benefit greatly from the USB Hubs that are jointly used with the True Emulation system. Because they interface directly and permanently with each computer, they help to stabilize the dormant links, making errors during enumeration much less likely. The dual switching arrangement provides further flexibility because the True Emulation and enumerated sections can be switched in unison or independently of each other, as required. Thus, your various peripherals can operate with different computers at the same time. OTHER USB KEYBOARD MOUSE DEVICE HOST CONTROLLER EMULATION ENGINE Figure A-1. True Emulation functional block diagram. The emulated section of the switch is shown in blue and handles only the keyboard and mouse. The green enumerated section of the switch handles other USB devices and also uses the USB hubs to link with the computers. 724-746-5500 | blackbox.com Page 37 Download from Www.Somanuals.com.
