1. Introduction Thank you for purchasing the LINDY CPU Switch Dual MP. Your LINDY CPU Switch Dual MP is a very high performance Keyboard, Video monitor and Mouse (KVM) sharing device which supports a wide range of computer hardware and software platforms. The LINDY CPU Switch Dual MP supports multiple users and enables each user to independently access the connected computers.
LINDY explains: What does KVM stand for? Throughout this manual the abbreviation KVM is used to refer to the combination of a Keyboard, Video monitor and Mouse that is used to access a computer. A KVM console usually consists of a keyboard, monitor and mouse although sometimes only a keyboard and monitor may be used. Devices such as the LINDY CPU Switch Dual MP are generally known as KVM sharers or KVM switches.
1.1 Key features and benefits Enables many computers to be independently controlled by two users. Enables desktop and laptop PCs, Sun (USB), Sun (8-pin), Mac (USB), SGI, Alpha and RS/6000 computers to be controlled from a common KVM console. USB keyboard and mouse support enables KVM console devices to be chosen that are the most appropriate for multi-platform control (keyboards and mice for all the main computer types are available in USB format).
Support for up to 16 user access profiles and 512 named computers. The colours and position of the OSD menu may be changed by each user. OSD routing status window shows the computers that are currently being controlled by the KVM consoles. Supports three computer control modes - Exclusive, Shared and Video Only. Optional small-sized reminder banner permanently confirms the selected computer.
Standard colour-coded cable connections make installation easy and inexpensive. Auto-scan list feature enables scanning of selected computers. 1.2 LINDY CPU Switch Dual MP package contents LINDY CPU Switch Dual MP.

2. Installation LINDY explains: Flexible configuration The LINDY CPU Switch Dual MP has many ports for connection to computers, keyboards, mice and monitors. There are no restrictions placed upon which ports are connected to devices and you can leave any of the ports disconnected if you wish. You do not need to connect a keyboard, monitor and mouse to each user port if you do not wish to use all of these.
PC PS/2 or RS232 two button mouse driver (any manufacturer). - Microsoft mouse driver (including IntelliMouse). - Logitech mouse driver (including two button, three button and wheel mouse). - You may also need one or more of the following adapters. These adapters may be obtained from your LINDY CPU Switch Dual MP supplier and other good retailers. Video adapter - 13W3 male connector to 15 pin D-type connector (LINDY Part No.
(e.g. the Stop, Again, Props and Undo keys for Sun systems). Sun keyboards have more keys than standard PC keyboards which have more keys than Mac keyboards and so if you are controlling a mixture of computers that include any Suns you are recommended to use a Sun keyboard. A USB mouse. The LINDY CPU Switch supports most ‘Internet / scroll mice’ that are compatible with the Microsoft IntelliMouse and Sun and Mac mice. 2.
Figure 3 - LINDY CPU Switch Dual MP cables. See appendix A for part numbers and ordering information To connect PCs with serial mouse connections and AT style keyboard connections use the PC cable together with the adapters specified in appendix A. If you have an existing 6-pin mini-DIN to 9-pin serial adapter that came with a mouse it may not be suitable for use with the LINDY CPU Switch as there are several different standard wiring configurations for these adapters.
To connect Sun computers with older style 13W3 video connections you will need to use the Sun cable together with a 13W3 to 15 way D-type video adapter. The LINDY CPU Switch is now ready for connection to the mains using the mains power adapter supplied. It is important to apply power to the LINDY CPU Switch first, then power on the monitor and each of the computers in turn.
mice, so ensure that your PC software is configured for a Microsoft mouse of the correct type. Refer to the list of supported drivers in section 2.1. 2.5 Structuring your LINDY CPU Switch Dual MP installation A single LINDY CPU Switch Dual MP 32354 may be used to manage and control up to 16 computers (see figure 4). For larger numbers of computers, Dual MP units may be cascaded in a tree structure with LINDY CPU Switch Dual products to form a video switching network (see figure 5).
The Dual MP unit should be used as the master (i.e. at the top of the tree). All other levels should be Dual products. Keep all cascade cables as short as possible. The video quality is maximised by using the shortest possible total cable run from computer to KVM. If you are making multiple cascade links then ensure that the cables are approximately the same length. You must choose groups of cascade ports from the following table.
The following diagrams show some typical LINDY CPU Switch Dual MP installations. Fig.
Fig.
2.6 Maximising the video quality The LINDY CPU Switch Dual MP supports very high bandwidth video signals and resolutions up to 1900 x 1440 pixels. It regenerates the video signals using wideband amplifiers in order to minimise any loss of video quality. All video cables introduce distortion onto the video signal. For short cables this is minimal but for longer cables the loss of quality can start to become noticeable particularly at higher video resolutions.
2.7 Other useful installation information Intelligent cables — The USB and Sun cables contain miniature active circuits that are moulded into the ends of the cable assembly. These circuits intelligently provide signals to your computers that make them think that a keyboard and mouse are continuously attached, even if the LINDY CPU Switch is not connected or powered on. This increases the reliability and robustness of the installation.
If you have switched off your LINDY CPU Switch or you are attempting to ‘hot plug’ it into a system that is already running, you may be able to restore lost mouse movement using the LINDY CPU Switch's mouse restoration functions. Mouse restoration functions should be used with care as unpredictable results may occur if the wrong mouse type is selected. If in doubt restore the mouse by powering down the PC normally.
3. Configuring the LINDY CPU Switch Dual MP 3.1 Configuration summary The LINDY CPU Switch is configured using the on-screen menu system which is activated by default when you first power on the system. It may also be accessed by using the keyboard 'hotkeys' (see section 4.8) or by using the LINDY CPU Switch's front panel keys (see section 4.6). The following steps summarise a typical configuration process.
Step 3 - Create user accounts Login to the LINDY CPU Switch using the ADMIN account and add user profiles and passwords for each of the system users (see section 3.4). The LINDY CPU Switch supports up to 16 user profiles. Step 4 - Add / edit names to identify your computers Whilst you are logged into the LINDY CPU Switch using the ADMIN account, create names for each of the computers that you have attached to the system.

you user name and password to access the LINDY CPU Switch. 4.8 Keyboard hotkeys The LINDY CPU Switch Dual MP can be conveniently controlled using special keyboard hotkey combinations. These hotkey combinations can be used to select computers and perform a number of other useful functions. All of the hotkey control commands are invoked by holding down the hotkeys and then pressing a command key.
‘HOTKEYs’ and ‘1’ - selects channel 1 ‘HOTKEYs’ and ‘2’ - selects channel 2 ‘HOTKEYs’ and ‘3’ - selects channel 3 ‘HOTKEYs’ and ‘4’ - selects channel 4 ‘HOTKEYs’ and ‘5’ - selects channel 5 ‘HOTKEYs’ and ‘6’ - selects channel 6 ‘HOTKEYs’ and ‘7’ - selects channel 7 ‘HOTKEYs’ and ‘8’ - selects channel 8 ‘HOTKEYs’ and ‘9’ - selects channel 9 ‘HOTKEYs’ and ‘1 then 0’ - selects channel 10 ‘HOTKEYs’ and ‘1 then 1’ - selects channel 11 ‘HOTKEYs’ and ‘1 then 2’ - selects channel 12 ‘HOTKEYs’ and ‘1 then 3’ - selec
Selects the channel specified by {number}. This allows ports on cascaded units to be selected. For example HOTKEYs + 0 1032354 would select port 1 (01) on the current LINDY CPU Switch, port 2 (02) on the next cascaded LINDY CPU Switch and port 16 on the last LINDY CPU Switch.
4.9 Selecting computers using the mouse Computers may conveniently be selected using a three button mouse. In order to switch to the next computer simply hold down the central mouse button (the wheel mouse button on an IntelliMouse) and click on the left hand mouse button to select the next computer. If password security has been set then the LINDY CPU Switch will select the next available channel, otherwise it will select the next numerical channel.
4.10 Selecting computers using the on-screen menu You can conveniently select computers by name using the LINDY CPU Switch's onscreen menu. For systems with many computers this is the recommended method of computer selection. The on-screen menu is called up by pressing the ‘HOTKEYs’ and the ‘M’ key together. Its position on the screen may be moved using the 'HOTKEYs' and the cursor keys (see section 4.
To connect to a computer, place the menu bar over the computer name using a combination of the up and down cursor keys and the page up / page down keys. You may also use the wheel on a wheel mouse to move the menu bar up and down if you have enabled mouse control (see section 3.6.8).
e To select the computer with SHARED access press: or f When a computer is selected in SHARED mode, the computer’s video picture will be displayed on all the KVM consoles that are connected to that computer. Only one user will have control of the computer’s keyboard and mouse at any one time. If no keyboard or mouse activity has been detected for the timeout period (see section 3.6.13) then other KVM consoles may gain control.
You may also use a 3-button mouse or wheel mouse to select a computer if you have enabled mouse control (see section 3.6.8). ) whilst To select a computer in SHARED mode use the left hand mouse button ( the menu bar is positioned above the required computer name. To escape without selecting a new computer use the right hand mouse button. To select a computer in EXCLUSIVE mode, use the left hand mouse button together with the SHIFT key on the keyboard.
LINDY CPU Switch indicates an unsuccessful connection 4.11 The reminder banner Normally the LINDY CPU Switch will display a discreet computer name reminder banner that reminds you which computer you are connected to. This banner will normally appear at the top of the screen in a central location and may optionally be disabled (see section 4.12.2). Many computer screens can look very similar and so this banner serves as a useful reminder of which computer you are working on.
4.12 Setting the USER PREFERENCES The USER PREFERENCES are system operating parameters that are independently selectable for each user. From the main menu press F1 for MORE MENUS. Use the cursor keys to position the menu bar over USER PREFERENCES Press ENTER or RETURN to view the preferences. Use the cursor keys to place the menu bar over the required option and then use SPACE BAR to change the option as required. Press ESC to quit and save the changes. 4.12.

This is normally located at the top of the screen in a central position but may be moved as required (see section 4.8) 4.12.3 REMINDER COLOUR Accessed from menu: USER PREFERENCES Settings: BLUE/TRANS, PINK/TRANS, BLUE/WHITE, WHITE/RED You may select the colour of the reminder banner. The BLUE/TRANS and PINK/TRANS select blue or pink text with a transparent background. The BLUE/WHITE and WHITE/RED settings select blue and white text on solid white and red backgrounds.
The ADMIN user is also given the option to RESET TO FACTORY DEFAULTS. This will clear all the computer and user names and set all parameters back to the factory defaults. To avoid activating this function by accident the administrator must confirm the reset instruction by pressing F8. See section 4.19 for details on using the SEND DATA TO RS232 PORT and READ DATA FROM RS232 PORT functions. These functions are only available to the Admin user. 4.
when configuring a cascade of LINDY CPU Switches are given in section 2.5. Although it is theoretically possible to select computers on cascaded units by pressing the hotkeys and then typing in the port address this would be highly confusing for users and is not generally recommended. Consequently it is normally advisable to use the on-screen menu to select computers on cascaded units.
4.17 Using the LINDY extender Refer to the installation guide provided with your LINDY extender. When using an LINDY extender we highly recommend that you set the extender's hotkeys to be different to the LINDY CPU Switch's hotkeys to avoid any confusion 4.18 What to do if you forget your ADMIN password If you forget your ADMIN account password you will not be able to access the LINDY CPU Switch Dual MP to add or edit users and computer names.

connectors). All data should be sent using the following RS232 protocol. Baud: 19200, bits: 8, stopbits: 1, parity:none No handshaking is implemented but valid command characters will be echoed back to the sender. The top nibble (4 bits) of the command byte defines the user port that is to be switched (1=port 1, 2=port 2). The bottom nibble defines the computer port that the user port is to be switched to (e.g. 0=port 1, 1=port 2, E=port 15, F=port 16).
You may decide to connect a Sun, PC or Macintosh style keyboard to the LINDY CPU Switch. Generally, Sun keyboards have more keys than PC keyboards which have more keys than Mac keyboards. It is generally advisable to use a keyboard with the maximum number of keys that are expected by any of the connected computers (i.e. if you are connecting any Suns then you are recommended to use a Sun keyboard).
If you are using a PC style controlling keyboard, the equivalent key mappings are: IBM 104/105-key keyboard Left Ctrl Left Win Start ( ) Left Alt Right Alt or Alt Graph Right Win Start ( ) Right Ctrl Win Right Mouse Click ( ) Right Ctrl+F1 Right Ctrl+F2 Right Ctrl+F3 Right Ctrl+F4 Right Ctrl+F5 Right Ctrl+F6 Right Ctrl+F7 Right Ctrl+F8 Right Ctrl+F9 Right Ctrl+F10 Right Ctrl+1 Right Ctrl+2 Right Ctrl+3 Right Ctrl+4 Right Ctrl+H Sun keyboard Apple keyboard Left Control Left Diamond ( ) Left Alt Alt Grap
5. Upgrading the LINDY CPU Switch's firmware The LINDY CPU Switch Dual MP uses flash memory technology which enables the firmware code to be upgraded by the user. New keyboards, mice operating systems and drivers are being launched all the time. From time to time the LINDY CPU Switch's firmware will be updated to provide support for these new devices. You can take advantage of these upgrades free of charge during the warranty period.
To perform a flash upgrade on the LINDY CPU Switch Dual MP: Step 1 - Prepare your computers Ensure that you have saved any important work on the connected computers. The LINDY CPU Switch Dual MP can be upgraded whilst attached to live systems but remember that the mouse connections will probably need to be reconstituted after the upgrade is finished (see sections 4.13 and 2.9). Where possible, mission critical servers should be switched off or disconnected before performing an upgrade.
Step 4 - Power off the LINDY CPU Switch Dual MP Remove the power from the Dual MP. Step 5 - Power on the LINDY CPU Switch with the UPGRADE switch ON Attach the power adapter to the LINDY CPU Switch whilst the UPGRADE switch is ON. The green USER display should now show a lower case 'u'. This indicates that the LINDY CPU Switch is ready to be upgraded. The display should now show: Step 6 - Run the upgrade program The latest version of the LINDY CPU Switch Dual MP firmware is available from LINDY .
characters represent the firmware release version (e.g. 129 equals version 1.29). 3) A data file that tells the upgrade program (LYDMP.EXE) which binary code files (HEX files) to download to the LINDY CPU Switch Dual MP and where to put each file. Theoretically this DAT file can be modified so that only certain processors are upgraded but do not do this unless specifically instructed by LINDY technical support. e.g. M216V129.
IMPORTANT NOTE The upgrade programs are DOS based to enable compatibility with the widest range of operating systems. They run efficiently on DOS, Windows 3.X, Workgroups, 95, 98, ME and Windows NT. The upgrades will take approximately 10 minutes but vary slightly according to the LINDY CPU Switch model and the speed of the PC. Upgrades run from PCs using Windows 2000 will take very substantially longer due to the way that this operating system handles the DOS programs.
6. Special features of the Dual MP 6.1 Synchronising LINDY CPU Switch Dual MPs for multiple video head applications Multiple LINDY CPU Switch Dual MPs may be connected together so that they operate in a synchronised manner. Synchronised operation is useful for applications that require multiple video signals to be switched together. This type of operation is usually required where each computer is fitted with multiple video cards or video cards with multiple video heads.
Synchronised LINDY CPU Switches used for a Dual head video switching application The pinout of the RS232 synchronisation cable is as shown below.
The pinout for a “daisy chain” RS232 cable for more than 2 units is shown below: 6.2 Logging access activity By connecting the LINDY CPU Switch’s serial port to a computer, a time stamped log of the LINDY CPU Switch’s activity can be generated. This is useful for applications where it is necessary to keep track of which users have accessed which computers. A simple data logging program may be downloaded from the LINDY website (LYLOG.EXE).
{activity_log_destination} is the file name where the log is to be stored or the word PRINT if the log is to be printed on a printer attached to the computer’s parallel port. LPT1 {com_port} is the computer’s serial port that is connected to the LINDY CPU Switch. Options are 1 (for COM1) or 2 (for COM2). For example: LYLOG datalog.txt 1 would log activity information received on COM1 to the file datalog.txt.
