Lindy CPU SWITCH warranty Re-enabling a disconnected PS/2 mouse, Important Note

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 LINDY CPU Switch 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 LINDY CPU Switch 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 2.6 for details.

Keyboard and mouse mode switching - The LINDY CPU Switch 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 LINDY CPU Switch channel is switched thus ensuring maximum software compatibility. The <NUM LOCK>, <CAPS LOCK> and <SCROLL LOCK> states are an obvious example of this process.

2.6Re-enabling a disconnected PS/2 mouse

If you disconnect the shared PS/2 mouse from the LINDY CPU Switch 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 LINDY CPU Switch is fitted with an automatic mouse recovery system.

With the PS/2 mouse disconnected, change the channel using the keypad or keyboard hotkeys. The LINDY CPU Switch detects that the mouse has been disconnected and triggers the automatic recovery system. Plug in the PS/2 mouse and the LINDY CPU Switch will re-initialise it.

Alternatively you can reset the keyboards and mice by holding the SELECT and AUTO keys down together for 5 seconds. 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 ports A and B. It does not affect the status of any of the other ports on the switch or the CPU connections.
