2. Installation LINDY explains: Flexible configuration The LINDY CPU Switch Dual Junior 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.
For the user port connections you will need: A monitor with a standard VGA-style 15-pin analogue video connector that will work when connected directly to each of your PCs. LINDY CPU Switch Dual Junior supports low and high resolution monitors. A PS/2 or AT style keyboard. If you are using an AT keyboard with a 5-pin connector you may connect this to the LINDY CPU Switch Dual Junior using a standard AT to PS/2 keyboard adapter.
2.3 Connecting your devices Ensure that the power is disconnected from the LINDY CPU Switch and all devices which are to be attached. Connect any keyboards, monitors and mice to the user port connectors at the rear of the LINDY CPU Switch (see figure 2). The individual connectors are colour coded for your convenience. If you are connecting several KVM (Keyboard, Video monitor, Mouse) sets then you do not need to use the same brands or mix of devices on each user port.
2.4 Configuring your PCs Configure your PC in the same way that you would if your keyboard, mouse and monitor were all connected directly to your PC, but bearing in mind the following point: LINDY CPU Switch emulates Microsoft compatible serial, IntelliMouse and PS/2 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.
When cascading LINDY CPU Switch Dual Junior keep in mind the following rules The maximum number of layers in a LINDY CPU Switch Dual Junior cascade is four. You may cascade Dual Junior units with 1 or 2 KVM links. The number of KVM links that you install defines the number of simultaneous uses that are supported. 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.
The following diagrams show some typical LINDY CPU Switch Dual Junior installations.

2.6 Maximising the video quality The LINDY CPU Switch Dual Junior 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 PC boot up sequence - When your PCs are powered on they communicate with any attached keyboards and mice and setup parameters required by the particular operating system. It is necessary for the LINDY CPU Switch to be attached and powered on during this sequence so that it can give the required responses and keep track of all the modes and settings requested by each of the connected PCs.
Alternatively you can reset the keyboard and mouse for a given user port by using the LINDY CPU Switch's keyboard and mouse reset function (see section 4.16). This function only resets the keyboard and mouse attached to the selected user port. It does not affect the status of any of the LINDY CPU Switch's other ports or the CPU connections. 2.

LINDY CPU Switch. The IntelliMouse setting sends four byte mouse reports to the computers and is therefore very slightly more sluggish than the others that send three byte mouse reports. RS232 mice are almost always more sluggish than PS/2 types because the data rate is much slower.
4. Using the LINDY CPU Switch Dual Junior This section explains the general operation of the LINDY CPU Switch Dual Junior. We recommend that you read this section before starting to use the product. 4.1 Rear panel special function switches Before powering on the LINDY CPU Switch ensure that the two option switches on the rear are set to the OFF (up) position. Option switch 1 is reserved for future use and option switch 2 is used to enable firmware upgrades (see section 5). 4.
4.4 COMPUTER display and key switch The COMPUTER key selects the computer port that is to be connected to the user port that is currently displayed on the green USER display (see figure 1). Pressing the key will cause the red COMPUTER display to change to the next available computer port in numerical sequence. The next available computer port is defined by the way that the LINDY CPU Switch Dual Junior is configured. There are two special computer ports that may be selected using the COMPUTER key switch.
4.5 Activity indicators The LINDY CPU Switch Dual Junior has a front panel activity indicator for each user port (see figure 1). The indicator will flash when keyboard or mouse data is received by the LINDY CPU Switch.

be selected. For example HOTKEYs + 0 10216 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 3.6.7).
To select the computer with SHARED access press: e 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 3.6.12) 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 3.6.7). To select a computer in SHARED mode use the left hand mouse button ( ) whilst 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.

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. 4.12.
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. 4.14 Querying the routing status It is sometimes useful to know which KVM consoles are connected to which computers and their connection modes (shared, exclusive or video only).
However it is sometimes useful to be able to connect to ports on cascaded units via a specific cascade cable (rather than the first available of a group) in order to check that the cabling is working as expected. To do this you can use a hotkey sequence similar to the example shown below. For example to connect to port 14 on a LINDY CPU Switch Dual Junior that is cascaded off port 1 of your first LINDY CPU Switch Dual Junior.
user port whose keyboard and mouse you wish to reset. 2) The selected user port number should now be shown on the green USER display. 3) Press and hold down the USER key for 5 seconds until the green USER display goes off. The keyboard and mouse will then be powered off. 4) As soon as the green display goes off you may release the USER key. The green display will then come back on and a few seconds later the keyboard and mouse will be powered on and ready for use. 4.
4.19 Saving and restoring the menu configuration to and from an Excel compatible file. The LINDY CPU Switch Dual Junior will store up to 512 computer names and 16 sets of user access rights. If you have a cascade of LINDY CPU Switches then it may take some time to enter all the computer names and port numbers and decide on the access rights that you are going to grant to each user profile. Consequently, for peace of mind it is useful to be able to store these settings.
To edit the menu names and configuration settings: You may open the LDJDATA.CSV using a spreadsheet program such as Microsoft Excel. The format of a typical file is shown below. You will see that the computer names (rows) are tabulated against the user profiles (columns). To grant a user access to a computer, enter the value 1 in the box that is common to the computer’s row and the user’s column. To deny access, leave this box blank. To add extra users, add additional columns (up to 16 users).
5. The LINDY CPU Switch should then receive the configuration data to your computer and load the new menu names and access rights into the menu. 4.20 Switching channels by sending RS232 data You can switch the LINDY CPU Switch Dual Junior remotely by sending RS232 data to the serial communications port (located on the rear panel adjacent to the power connectors). All data should be sent using the following RS232 protocol.
5. Upgrading the LINDY CPU Switch's firmware The LINDY CPU Switch Dual Junior 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 Junior: Step 1 - Prepare your computers Ensure that you have saved any important work on the connected computers. The LINDY CPU Switch Dual Junior 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 Junior Remove the power from the Dual Junior. 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.
represent the firmware release version (e.g. 129 equals version 1.29). 3) A data file that tells the upgrade program (LYDJNR.EXE) which binary code files (HEX files) to download to the LINDY CPU Switch Dual Junior 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. 216V129.DAT Like the hex files, the first three digits represent the model number (e.g.
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.
Appendix A. Cable and connector specifications IMPORTANT NOTE The maximum cable lengths supported vary widely between devices and cables. It may be possible to use cables that are longer than those specified below with certain PCs and peripherals but this cannot be guaranteed. If you experience problems try using shorter cables. A1.
