An ‘r’ will show briefly on the display to confirm that the reset has been completed. 4.7 Setting a security password There are many situations where unrestricted access to corporate file servers or sensitive information needs to be controlled. In such circumstances, the SmartView Multiscreen can be locked away in a room or secure cabinet and controlled remotely. In this mode typing the keyboard hotkeys together with 'L' will blank the screen, disconnect the keyboard and mouse from all of the computers and display ‘P’ on the SmartView Multiscreen display. Control can only be regained by typing the correct password on the keyboard. To set the password in configure mode, first type ‘P’ then (return). The display on SmartView Multiscreen will change to show ‘=' and you can then type your password. The password is not case sensitive and can be any combination of key strokes, including the function keys, but excluding the (ctrl), (alt), (shift) and (return) keys. When you have typed in your password type (return) to register it in the stored memory. Do not worry if you type the password incorrectly, you can always re-enter configure mode and set the password again. If you have lost the password and the SmartView Multiscreen is locked, the unit may be unlocked by powering down the SmartView Multiscreen, entering configure mode at power on (see section 2.6), and performing a complete reset using the F8 function. NOTE - The password consists of a combination of key strokes rather like the code to a safe. The key strokes are not case sensitive and can include all the keys on the keyboard (except ctrl, alt, shift and enter). Consequently the following 'password' would be valid: oFRED oFREDoFREDg gg SmartView Multiscreen Installation and Use Page 35 4.8 Cascade query code The SmartView Multiscreens use a special ‘query code’ to detect whether or not they are connected to another SmartView Multiscreen. By default your SmartView Multiscreen uses query code AD. SmartView Pro (another range of keyboard / mouse / video switches from Adder Technology) units with firmware versions less than 1.09 used query code EF. This was found to conflict with a small number of other (rare) devices that used the same query code so an alternative query code was provided to ensure compatibility. Either query code may be used but you should make sure that all cascaded SmartView Multiscreen and SmartView Pro units are set to use the same query code. If any of the cascaded SmartView Pros have firmware versions less than 1.09 then the cascade query code for all the SmartView Multiscreens and SmartViews should be set to EF. L7 – Cascade query code = AD (default) L8 – Cascade query code = EF 4.9 Resolving slow mouse problems Due to certain technical reasons some systems running particular combinations of operating system and mouse drivers are sensitive to small timing changes relating to mouse communications. The introduction of a switch like the SmartView inevitably causes some timing changes and in rare cases interactions have been observed that causes the mouse to run very slowly. Certain HP Vectra computers running later versions of Windows NT with Logitech mouse drivers and Logitech mice have been observed to exhibit such interactions with older switches. One solution to this problem is to change the mouse driver. The SmartView Multiscreen is a high performance device that is carefully engineered to minimise such interactions and should not exhibit this characteristic. Nevertheless such interactions are unpredictable and so the SmartView is fitted with a feature that ensures that the mouse can never operate at a very slow rate regardless of such interactions. This feature is activated using the following options: L5 – Allow the mouse to run at any speed (default) L6 – Don't allow the mouse to run at very slow speeds SmartView Multiscreen Installation and Use Page 36 4.10 Exit configure mode When you have finished configuring any special options, simply type ‘E’ followed by (return) to exit configure mode and return to normal operation mode. The attached computers can now be switched on. SmartView Multiscreen Installation and Use Page 37 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. Keyboard, monitor and mouse to SmartView Multiscreen All of the shared devices plug directly into the relevant ports at the rear of the SmartView Multiscreen. If you use an AT style keyboard you will need an AT (5 pin DIN female) to PS/2 (6 pin mini-DIN male) converter. Cable specification (self-powered operation): Keyboard, monitor and mouse cables should be no longer than 2 metres. Cable specification (with optional power adapter): Keyboard, monitor and mouse extension cables ca...
