It is necessary for the SmartView Multiscreen 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. Mouse characteristics - do not unplug a PS/2 mouse connection from a PC whilst the PC is on. Due to the design of PS/2 mice communications the mouse function on the PC will be lost and you will have to re-boot the PC to regain normal operation. Unplugging the mouse from the SmartView Multiscreen will also cause it to stop operating when it is plugged back in. RS232 mice can usually be unplugged and plugged back in provided that a mouse was connected when the operating system initially booted. The SmartView Multiscreen is fitted with a PS/2 mouse recovery system which allows you to disconnect and re-connect the shared mouse without powering down the system (although this is generally not advisable) - see section 2.10 for details. Keyboard and mouse mode switching - The SmartView Multiscreen keeps a log of the keyboard and mouse mode and resolution settings requested by each of the connected PCs. These settings are automatically restored to the shared keyboard and mouse when the SmartView Multiscreen channel is switched thus ensuring maximum software compatibility. The keyboard num, caps and scroll lock states are an obvious example of this process. 2.10 Re-enabling a disconnected PS/2 mouse If you disconnect the shared PS/2 mouse from the SmartView Multiscreen by accident during operation then the mouse operation will be lost when the mouse is plugged back in. To avoid having to reboot the entire system in this situation the SmartView Multiscreen is fitted with an automatic mouse recovery system. With the PS/2 mouse disconnected, change the channel using the keypad or keyboard hotkeys. The SmartView Multiscreen detects that the mouse has been disconnected and triggers the automatic recovery system. Plug in the PS/2 mouse and the SmartView Multiscreen will re-initialise it. Alternatively you can reset the keyboards and mice by holding down the front panel key for 5 seconds. When the character ‘C’ is displayed on the front of the SmartView SmartView Multiscreen Installation and Use Page 18 Multiscreen, press the front panel key again. A complete power off reset of the connected keyboards and mice will then be performed. This function only resets the shared keyboard and mice that are plugged into the control port. It does not affect the status of any of the other ports on the switch or the CPU connections. 2.11 Hot plugging the SmartView Multiscreen into running systems and re-enabling disconnected CPU PS/2 mouse connections It is advisable to switch off the systems that are going to be connected to the SmartView Multiscreen before installation. However, if this is not possible then most systems can be hot plugged by using the SmartView Multiscreen’s mouse restoration functions. The keyboard connection will normally restore itself automatically. On many PCs, mouse movement will be lost if the PS/2 mouse is unplugged and plugged back in whilst the PC is running. Mouse movement can then only be restored by rebooting the PC. This is because the mouse drivers only setup and enable the mouse when the PC is initially booted. If you have switched off your SmartView Multiscreen 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 SmartView Multiscreen'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. Standard PS/2 mouse data uses a different data format to IntelliMouse data and so two reset functions are provided on the SmartView Multiscreen. The type of data format expected by the PC depends upon the driver and the type of mouse that was connected when the driver was booted. The following table may be used as a guide. Note that the mouse reset functions predict the likely mouse resolution settings but may not restore the speed or sensitivity of the mouse exactly as they were when the PC originally booted.
