9 Chapter 1. Introduction his chapter introduces you to the ACS-1208A / ACS-1216A KVM Switch. Its Tpurpose, features and benefits are presented, and its front and back panel components are described. Overview The Master View ACS-1208A and ACS-1216A KVM Switches are control units that allow access to multiple computers from a single console (keyboard, mouse, and monitor). Before the development of the Master View, the only way to control multiple computer configurations from a single console was through a complex and costly network system. Now, with the ACS-1208A / ACS-1216A, you can easily access multiple computers in a cost effective manner. A single Master View can control up to eight (ACS-1208A) or 16 (ACS-1216A) computers. As many as 31 additional switches can be added in a daisy chain configuration, allowing up to 512 computers to be controlled from a single keyboard-monitor-mouse console. An auto-sensing function recognizes the position of each station (switch) on the chain, eliminating the need to manually set the position with DIP switches. A seven segment front panel LED displays each Station s position for easy identification. The ACS-1208A / ACS-1216A improves on previous models and similar switches commonly found on the market with a custom ASIC (patent pending) for increased reliability and enhanced performance, and high density 15 pin CPU port connectors instead of the usual 25 pin connectors. This space-saving innovation allows a full, 16 port switch, to be installed in a 1U system rack. 1-1

10 Your ACS-1208A / ACS-1216A investment is protected by an included Firmware Upgrade Utility. You can stay current with the latest improvements in functionality by downloading the latest firmware files from our website and using the utility to quickly and conveniently perform the upgrade. Setup is fast and easy; plugging cables into their respective ports is all that is entailed. The ACS-1208A / ACS-1216A intercepts keyboard input directly, which means that there is no software to configure, no complex installation routines, and no need to be concerned with incompatibility problems. Access to any computer on the installation is easily accomplished either by entering Hotkey combinations from the keyboard, or by means of a powerful menu driven OSD (On Screen Display) system. A convenient Auto Scan feature also permits automatic scanning and monitoring of the activities of all computers running on the installation one by one. There is no better way to save time and money than with a Master View ACS-1208A / ACS-1216A installation. By allowing a single console to manage all of the attached computers, an ACS-1208A / ACS-1216A installation: (1) eliminates the expense of having to purchase a separate keyboard, monitor, and mouse for each computer; (2) saves all the space those extra components would take up; (3) saves on energy costs; and (4) eliminates the inconvenience and wasted effort involved in constantly moving from one computer to another. 1-2

21 Chapter 2. Installation his chapter explains how to connect up your installation from a basic single Tstage arrangement to a complete daisy chained configuration. Before you Begin 1. Make sure that power to all the devices you will be connecting up have been turned off. You must unplug the power cords of any computers that have the Keyboard Power On function. Otherwise, the switch will still receive power from the computers. 2. To prevent damage to your equipment, make sure that all devices on the installation are properly grounded. Single Stage Installation In a Single Stage installation, there are no additional switches daisy chained down from the first unit. To set up a single stage installation do the following: 1. Plug your keyboard, mouse, and monitor into the unit s Console Ports. 2. Use KVM cable sets (as described in the Cables section on p. 1-5), to connect any available CPU Port to the Keyboard, Video and Mouse ports of the computer you are installing. Note: Ignore the Daisy Chain Ports at this time. They are only used when daisy chaining additional Master View units. Daisy chaining is described in the next section. 2-1

22 3. Plug the power adapter cable into the Master View s Power Jack, then plug the power adapter into an AC power source. 4. Turn on the power to the computers. Daisy Chaining To control even more computers, up to 31 additional switches can be daisy chained down from the first unit. As many as 512 computers can be controlled from a single console in a complete installation. Tables showing the relation between the number of computers and the number of Master View ACS-1208A / ACS-1216A units needed to control them are provided on p. A-1 in the Appendix. To set up a daisy chained installation, do the following: 1. Make sure that power to all the devices you will be connecting up has been turned off. 2-2

23 Installation 2. Use a daisy chain cable set (described in the Cables section, p. 1-5), to connect the Chain Out port of the parent switch to the Chain In port of the child switch (First Station Out to Second Station In, Second Station Out to Third Station In, etc.). Note: You cannot use the Chain In port of the First Station Master View, since it is the highest level parent. 3. Use KVM cable sets (described in the Cables section, p. 1-5), to connect any available CPU Port on the ACS-1208A / ACS-1216A installation to the Keyboard, Video and Mouse ports of the computers you are installing. 4. Repeat the above steps for any additional ACS-1208A / ACS-1216A units you wish to add to the chain. 5. Power up the installation according to the following procedure: a) Plug in the power adapter for the First Station. Wait for the unit to ascertain its Station ID and display it on the Station ID LED. (The Station ID for the First Stage unit is 01, the ID for the Second Stage unit is 02, the ID for the Third Stage unit is 03, etc.). b) Plug in the power adapters for each Station on the installation in turn (Second Station, then Third Station, etc.). In each case, wait for the Station ID to be ascertained and displayed on the current Station before plugging in the next one. c) After all the Stations are up, power on the computers. 2-3

25 Installation Hot Plugging The ACS-1208A / ACS-1216A supports hot plugging - components can be removed and added back into the installation by unplugging their cables from the ports without the need to shut the unit down. In order for hot plugging to work properly, however, the procedures described below must be followed: Switching Station Positions: You can switch station positions by simply unplugging from the old parent and plugging into a new one. After you do, in order for the OSD menus to correspond to the change, you must reset the Station IDs in the OSD. See RESET STATION IDS, p. 4-11, for details. Hot Plugging CPU Ports: In order for the OSD menus to correspond to a CPU port change, you must manually reconfigure the OSD to reflect the new port information. See SCAN/SKIP MODE under the F3 SET function (p. 4-6), and the two Set Port selections under the F4 ADM function (p. 4-8), for details. Note: If the computer s Operating System does not support hot plugging, this function may not work properly. Hot Plugging Console Ports: The keyboard, monitor, and mouse can all be hot plugged. When hot plugging the mouse: a) You may unplug and replug the mouse (to reset the mouse, for example), as long as you use the same mouse. b) If you plug in a different mouse, all the stations and all the computers on the installation must be shut down for 10 seconds, then restarted following the Power Up Sequence described under Step 5 on p. 2-3.) Note: If, after hot plugging there is no response to keyboard and/or mouse input, perform a Keyboard and Mouse Reset by pressing in the Reset button (see p. 1-8). 2-5

26 Port ID Numbering Each CPU port on a Master View installation is assigned a unique Port ID. The Port ID is made up of two parts: a two-digit Station Number, and a two-digit Port Number: w The Station Number - reflects the switch s position in the daisy chain sequence. This corresponds to the number displayed on the front panel Station ID LED. w The Port Number - reflects the port on the Station that the computer is connected to. w The Station Number precedes the Port Number. w Station and Port numbers from 1-9 are padded with a preceding zero, so they become For example, a computer attached to Port 6 of Station 12 would have a Port ID of: Powering Off and Restarting If it becomes necessary to Power Off one of the switches, unplug its power adapter cable from the power jack. Before starting it back up you must do the following: 1. Shut down all the computers that are attached to it. Note: Unplug the power cords of any computers that have the Keyboard Power On function. Otherwise, the switch will still receive power from the computers. 2. Wait 10 seconds, then plug the Master View back in. 3. After the ACS-1208A / ACS-1216A is up, Power On the computers. Note: If you have shut down more than one Station, power up the highest Station first and work your way down to the lowest one. 2-6

27 Chapter 3. Hotkey Operation his chapter details the concepts and procedures involved in the Hotkey operation Tof your ACS-1208A / ACS-1216A installation. Hotkey Port Access Hotkey port access allows you to provide KVM focus to a particular computer directly from the keyboard. The Master View ACS-1208A / ACS-1216A provides the following Hotkey port access features: w Selecting the Active Port w Auto Scanning w Skip Mode Switching Invoking Hotkey Mode All Hotkey operations begin by invoking Hotkey Mode. Invoking Hotkey Mode takes three steps: 1. Hold down the Num Lock key; 2. While the Num Lock key is down, press and release the asterisk or the minus key; 3. Release the Num Lock key: or: [Num Lock] + [*]; [Num Lock] + [-]; Note: The asterisk or minus key must be released within one half second, otherwise Hotkey invokation is cancelled. 3-1

28 When Hotkey Mode is active: w The Caps Lock and Scroll Lock LEDs flash in succession. They stop flashing and revert to normal status when you exit Hotkey Mode. w A Command Line appears on the monitor s screen. The command line prompt is the word Hotkey: and appears in yellow text on a blue background. Subsequent Hotkey information that you key in displays on this line, as well. w Ordinary keyboard and mouse functions are suspended - only Hotkey compliant keystrokes and mouse clicks (described in the sections that follow), can be input. Pressing [Esc] exits Hotkey Mode. Selecting the Active Port Each CPU port is assigned a Port ID (see Port ID Numbering, p. 2-6). You can directly access any computer on the installation with a Hotkey that specifies the Port ID of the CPU Port that it is connected to. The steps involved are: 1. Invoke Hotkey Mode (see p. 3-1). 2. Key in the Port ID The Port ID numbers display on the Command Line as you key them in. If you make a mistake, use [Backspace] to erase the wrong number. 3. Press [Enter] The KVM focus switches to the designated computer and you automatically exit Hotkey Mode. 3-2

29 Hotkey Operation Auto Scanning Auto Scan automatically switches among all accessible CPU Ports at regular intervals, so that the operator can monitor their activity without having to switch among them manually. (See Scan/Skip Mode of the OSD F3 SET function, p. 4-7 for information regarding accessible ports.) Setting the Scan Interval: The amount of time Auto Scan dwells on each port is set with the Scan Duration setting of the OSD F3 SET function (see p. 4-7). This setting can be changed before activating Hotkey Auto Scanning with the following combination: 1. Invoke Hotkey Mode (see p. 3-1). 2. Key in [T] [n] Where [T] is the letter T, and [n] is a number from that represents the number of seconds for the dwell time. The letter T, and the numbers display on the Command Line as you key them in. If you make a mistake, use [Backspace] to erase the wrong number. 3. Press [Enter] You automatically exit Hotkey Mode, and are ready to invoke Auto Scanning. 3-3

30 Invoking Auto Scan: To start Auto Scanning, key in the following Hotkey combination: 1. Invoke Hotkey Mode (see p. 3-1). 2. Press [A]. You automatically exit Hotkey Mode, and enter Auto Scan Mode. The KVM focus switches among the accessible computers at regular intervals. While you are in Auto Scan Mode, note the following: w You can pause the scanning in order to keep the focus on a particular computer either by pressing P or with a Left Click of the mouse. During the time that Auto Scanning is paused, the Command Line displays the message: Auto Scan: Paused. Pausing when you want to keep the focus on a particular computer is more convenient than Exiting Auto Scan Mode because when you resume scanning, you start from where you left off, instead of starting over from the very first computer on the installation. To resume Auto Scanning, press any key or Left Click. w While Auto Scan Mode is in effect, ordinary keyboard and mouse functions are suspended - only Auto Scan Mode compliant keystrokes and mouse clicks can be input. You must exit Auto Scan Mode in order to regain normal control of the console. 3. To exit Auto Scan Mode press [Esc] or [Spacebar]. Auto Scanning stops when you exit Auto Scan Mode. 3-4

31 Hotkey Operation Skip Mode Skip Mode allows you to switch between computers in order to monitor them manually. Unlike Auto Scanning, which automatically switches after a fixed interval, you can dwell on a particular port for as long or as little as you like. To invoke Skip Mode, key in the following Hotkey combination: 1. Invoke Hotkey Mode (see p. 3-1). 2. Key in [Arrow] Where [Arrow] refers to one of the Arrow keys. After you press [Arrow], you automatically exit Hotkey Mode, and enter Skip Mode where you can switch ports as follows: Skips from the current port to the first accessible port previous to it. (See Scan/Skip Mode, p. 4-7, for information regarding accessible ports.) Skips from the current port to the next accessible port. Skips from the current port to the last accessible port of the previous Station. Skips from the current port to the first accessible port of the next Station. While you are in Skip Mode, note the following: w You can keep on skipping by pressing the Arrow keys. You don t have to invoke Hotkey mode each time you want to skip. w While Skip Mode is in effect, ordinary keyboard and mouse functions are suspended - only Skip Mode compliant keystrokes can be input. You must exit Skip Mode in order to regain normal control of the console. 1. To exit Skip Mode, press [Esc] or [Spacebar]. 3-5

32 Hotkey Beeper Control The Beeper (see Activate Beeper, p. 4-9) can be Hotkey toggled On and Off. To toggle the Beeper, key in the following Hotkey combination: 1. Invoke Hotkey Mode (see p. 3-1). 2. Press [B] After you press B, the Beeper toggles On or Off. The Command Line displays Beeper On or Beeper Off for one second; then the message disappears and you automatically exit Hotkey Mode. Hotkey Summary Table [Num Lock] + [*] or [Num Lock] + [-] [Port ID] [Enter] Switches access to the computer that corresponds to that Port ID. [T] [n] [Enter] Sets the Auto Scan interval to n seconds - where n is a number from [A] Invokes Auto Scan Mode. When Auto Scan Mode is in effect, [P] or Left Click pauses Auto Scanning. Pressing Any Key or another Left Click resumes Auto Scanning. [ ] [ ] [ ] [ ] [B] Invokes Skip Mode and Skips from the current port to the first accessible port previous to it. Invokes Skip Mode and Skips from the current port to the next accessible port. Invokes Skip Mode and Skips from the current port to the last accessible port of the previous Station. Invokes Skip Mode and Skips from the current port to the first accessible port of the next Station. Toggles the Beeper On or Off. 3-6

33 Chapter 4. OSD Operation his chapter provides a complete description of the procedures involved in the OSD T(On Screen Display) operation of your ACS-1208A / ACS-1216A installation. OSD Operation OSD Overview The On Screen Display (OSD) is a menu driven method to handle computer control and switching operations. All procedures start from the OSD Main Screen. To pop up the Main Screen, tap the [Scroll Lock] key twice. Note: You can optionally change the Hotkey to the Ctrl key, in which case you would tap [Ctrl] twice (see OSD HOTKEY, p. 4-6). With this method, the [Ctrl] keys must be on the same side (both left, or both right). The OSD incorporates a two level (Administrator / User) password system. Before the OSD Main Screen comes up, a dialog box appears that asks you to provide your password. If the password function has been set, you must provide the password in order to access the OSD Main Screen. If this is the first time that the OSD is being run, or if the password function has not been set, simply press [Enter]. The OSD Main Screen comes up in Administrator Mode. In this mode, you have Administrator privileges, with access to all Administrator and User functions, and can set up operations (including password authorization for the future), as you would like. 4-1
