Chapter 1. Introduction Overview The ALTUSEN 16-Port LCD Console KVM Switch offers a highly efficient network management solution. Custom designed high-density CPU connectors allow a 16-port KVM switch to fit into a 1U high rack space. Additional ALTUSEN switches can be daisy chained to the KL0116, allowing up to 512 computers to be controlled from its LCD console.
You can easily access to any computer on the installation either by entering Hotkey combinations from the keyboard, or by using the powerful menu driven OSD system. A convenient Auto Scan feature also permits automatic scanning and one-by-one monitoring of the activities of selected computers.
Features The main features of the KL0116 are as follows: w A single slide-out console integrated with the KVM switch controls up to 16 computers directly w Slide-out console features a 15" LCD monitor that can tilt back to a 30 viewing angle.
Benefits The KL0116 saves time and money by allowing a single console to manage all of your computers.
Cables Substandard cables may damage the connected devices or degrade overall performance. For optimum signal integrity and to simplify the layout, we strongly recommend that you use the high quality CS Custom Cable sets described below: Function CS Part Number KVM Switch to KVM Switch (Daisy Chaining) KL1700 - 0.6 m KL1701 - 1.8 m KVM Switch to Computer KL5201P - 1.2 m KL5202P - 1.8 m KL5203P - 3.0 m KC1700 / KC1701 KC5201P / KC5202P / KC5203P Note: 1.

Daisy Chain Port When Daisy Chaining Units, the Daisy Chain cable plugs in here. 4. CPU Port Section The KVM cables that link to the computers plug in here. Because of the connector shape, only cables designed to work with this switch (see p. 5) can plug in.
5. Remote Console Port The KL0116 can be operated from a remote console up to 500 feet (150 meters) away with the optional purchase of a KA9250 Console Extender Module. If the Extender Module is used, its cable plugs into this RJ-45 connector. See the Remote Console Operation chapter (p. 45) and the LCD Operation section (p. 50) for details about remote console operation. 6. Firmware Upgrade Port The KL0116’s firmware can be upgraded.
Chapter 2. Installation 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. Use KVM cable sets (as described in the Cables section on p. 5), to connect any available CPU Port to the Keyboard, Video and Mouse ports of the computer you are installing. Note: Disregard the Daisy Chain Port at this time. It is only used for daisy chaining a KH0116 switch to the KL0116.
Daisy Chaining To control even more computers, up to 31 additional ALTUSEN KVM switches can be daisy chained down from the KL0116. Note: KH0116 switches are used for daisy chaining, since there is no need for consoles on the chained switches. The KH0116 is similar to the KL0116, except that it comes in a standard housing without the slide-out console. Tables showing the relation between the number of computers and the number of switches needed to control them are provided on p. 47.
3. For additional KH0116 switches, use daisy chain cable sets to connect the Chain Out port of the parent KH0116 to the Chain In port of the child (Second Station Out to Third Station In, Third Station Out to Fourth Station In, etc.). 4. Use KVM cable sets (described in the Cables section, p. 5), to connect any available CPU Port to the Keyboard, Video and Mouse ports of the computers you are installing. 5. Power up the installation as follows: a. Power on the First Station. b.
Hot Plugging The KL0116 supports hot plugging. You can remove or add components on the installation by unplugging their cables from the ports without shutting the unit down. In order for hot plugging to work properly, you must follow these procedures: Switching Station Positions: You can switch KVM 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.
Port ID Numbering Each CPU port on the KVM installation is assigned a unique Port ID. The Port ID is made up of two parts: a Station Number, and a Port Number: M The Station Number is a two digit number that reflects the switch’s position in the daisy chain sequence. M The Port Number - is a two digit number which reflects the port on the Station that the computer is connected to. M The Station Number precedes the Port Number.

Chapter 3. Hotkey Operation Hotkey Port Access Hotkey Port Access allows you to provide KVM focus to a particular computer directly from the keyboard. The KL0116 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. Press and release the minus key; 3.
When Hotkey Mode is active: w The Caps Lock, and Scroll Lock LEDs flash in succession. They stop flashing after you exit Hotkey Mode. w A command line displays on the monitor screen. The command line prompt is the word Hotkey: in yellow text on a blue background. Text that you key in displays on the command line after the prompt. w Ordinary keyboard and mouse functions are suspended. You can only input Hotkey compliant keystrokes and mouse clicks (as described in the sections that follow).
Auto Scanning Auto Scan automatically switches among all the active CPU Ports that are accessible to the currently logged on User at regular intervals, allowing him to monitor their activity automatically. (See Scan/Skip Mode of the OSD F3 SET function, p. 30 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. 29).
Invoking Auto Scan: To start Auto Scanning, key in the following Hotkey combination: 1. Invoke Hotkey Mode (see p. 17). 2. Press [A]. After you press A, you automatically exit Hotkey Mode; enter Auto Scan Mode; and Auto Scanning begins. w While you are in Auto Scan Mode, you can pause the scanning operation in order to keep the focus on a particular computer by pressing P or with a Left Click of the mouse. While Auto Scanning is paused, the Command Line displays: Auto Scan: Paused.
Skip Mode Skip Mode allows you to switch between computers in order to monitor them manually. You can dwell on a particular port for as long as you like - as opposed to Auto Scanning, which automatically switches after a fixed interval. To invoke Skip Mode, key in the following Hotkey combination: 1. Invoke Hotkey Mode (see p. 17). 2. Press [Arrow] Where [Arrow] refers to one of the Arrow keys.
Hotkey Summary Table The following table summarizes the KL0116’s Hotkey operations: [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 1 - 255. [A] Invokes Auto Scan Mode. When Auto Scan Mode is in effect, [P] or Left Click pauses Auto Scanning. When Auto Scanning is paused, pressing Any Key or another Left Click resumes Auto Scanning.
Chapter 4. OSD Operation OSD Overview The On Screen Display (OSD) is a menu driven method to set up the KL0116’s working environment and to control port switching operations. The OSD also provides security features for the KVM installation. For example, the administrator can assign access rights to the computers for each User on a port-by-port basis. All procedures start from the OSD Main Screen. To bring up the Main Screen, tap the [Scroll Lock] key twice.
Note: 1. The diagram depicts the Administrator’s Main Screen. The F4 and F6 functions are reserved for the Administrator and do not appear on the Users’ Main Screen. 2. OSD always begins in LIST view, with the highlight bar at the same position it was in the last time the OSD was closed. 3. Only the ports that have been set accessible by the Administrator for the currently logged in User are visible (see SET ACCESSIBLE PORTS, p. 33, for details).
OSD Main Screen Headings The following table describes the OSD’s Main Screen Headings: Heading Explanation SN-PN This column lists the Port ID numbers (Station Number - Port Number) for all the CPU ports on the installation. The simplest method to access a particular computer is move the Highlight Bar to it, then press Enter. QV If a port has selected for Quick View scanning (see Set Quick View Ports, p. 33), an arrowhead displays in this column to indicate so.
F1 GOTO: GOTO allows you to switch directly to a port either by keying in the port’s Name, or its Port ID. The bar at the bottom of the OSD screen prompts you to make a selection. ESC : ENTER : SELECT ADMINISTRATOR F1 : GOTO SN-PN QV 01-01 01-02 01-03 01-04 01-05 01-06 01-07 01-08 GOTO NAME MELODY 1. NAME 2. PORT (1) w To use the Name method, key in 1; key in the port’s NAME; then press [Enter]. w To use the Port ID method, key in 2; key in the port’s Port ID; then press [Enter].
F2 LIST: Many OSD functions only operate on the computers that the OSD lists (displays) on the Main Screen. The LIST function lets set the scope of which ports are listed. ESC : EXIT ENTER : SELECT ADMINISTRATOR F2 : LIST : UP : DOWN ALL QUICK VIEW POWERED ON QUICK VIEW + POWERED The LIST choices and their meanings are given in the table below: Choice Meaning ALL Lists all of the ports on the installation. POWERED ON Lists only the ports that have their attached computers Powered On.
F3 SET: SET allows the Administrator and each User to set up his own working environment. A separate profile for each is stored by the OSD and is activated according to the Username that was entered during Login. ESC : EXIT ENTER : SELECT ADMINISTRATOR F3 : SET : UP : DOWN OSD HOTKEY PORT ID DISPLAY PORT ID DISPLAY DURATION PORT ID DISPLAY MODE SCAN DURATION: 5 SEC SCAN/SKIP MODE SCREEN BLANKER: 10 HOTKEY COMMAND MODE To change a setting: 1.
Setting OSD HOTKEY Function Selects which Hotkey activates the OSD function: [Scroll Lock] [Scroll Lock] or [Ctrl] [Ctrl]. Since the Ctrl key combination may conflict with programs running on the computers, the default is the Scroll Lock combination. If you choose the Ctrl key combination, the keys both must be on the same side (both left, or both right). PORT ID DISPLAY POSITION Allows you to position where the Port ID display appears on the monitor.
(F3 SET: continued) Setting SCAN/SKIP MODE Function Selects which computers will be accessed under Skip Mode and Auto Scan Mode. (See F5 SKP, p. 34, and F7 SCAN, p. 36.) Choices are: ALL - All the Ports which have been set as Accessible (see SET ACCESSIBLE PORTS, p. 33); POWERED ON - Only those Ports which have been set as Accessible and are Powered On; QUICK VIEW - Only those Ports which have been set as Accessible and have been selected as Quick View Ports (see SET QUICK VIEW PORTS, p.
F4 ADM: F4 allows the Administrator to configure and control the overall operation of the OSD. After you select an item from the ADM menu, a submenu with further choices appears. An icon indicates which choice is currently selected .
(F4 ADM: continued) Setting SET LOGOUT TIMEOUT Function If there is no input from the console for the amount of time specified with this function, the currently logged in User is automatically logged out. A login is necessary before the console can be used again. This enables other Users to access the computers when the original User is no longer accessing them, but has not logged out. To set the timeout value, key in a number from 1 - 180 minutes, then press [Enter].
(F4 ADM: continued) Setting Function ACTIVATE BEEPER When activated, the beeper sounds whenever a Port is changed; when the Auto Scan function is activated (see F7 SCAN, p. 36); or an invalid entry is made on an OSD menu. Choices are: Y (to activate the beeper), or N (to disable the beeper). The default is Y (activated). SET QUICK VIEW PORTS This function lets the Administrator select which Ports to include as Quick View Ports.
(F4 ADM: continued) Setting RESET STATION IDS Function If you change the position of one of the Stations in the daisy chain, the OSD will no longer correspond to the new configuration. This function rescans the installation’s Station positions and updates the OSD. Note: Only the Station Numbers are updated. Except for the Port Names, you must redo all Administrator settings (such as Set Accessible Ports, Set Quick View Ports, etc.), for all of the KVM stations affected by the change.
F6 BRC: Broadcast Mode (BRC) is an Administrator only function. Under Broadcast Mode, commands sent from the console are broadcast to to all available computers on the installation. This function is particularly useful for performing operations on multiple computers, such as performing a system wide shutdown, or installing/upgrading software. BRC works in conjunction with the F2 LIST function (see p. 27).
F7 SCAN: The SCAN function (Auto Scanning) automatically switches the KVM focus among User-selected computers at regular intervals in order to monitor their activity without having to switch manually. w The selection of computers to be included for Auto Scanning is made with the Scan/Skip Mode setting under the F3 SET function (see p. 30). w The amount of time that the focus stays on each Port is set with the Scan Duration setting under the F3 SET function (see p. 29).
F8 LOUT: LOUT logs you out of OSD control of the computers, and blanks the Console screen. This is different from simply pressing [Esc] when you are at the Main Screen to deactivate the OSD. After using this function, you must log in all over again to regain access to the OSD, whereas with [Esc], all you have to do to reenter the OSD is tap the OSD Hotkey. Note: 1. When you reenter the OSD after logging out, you must input your username and password before you can continue. 2.
