Resetting your PS/2 keyboard and mouse

NOTE: This function is for Microsoft Windows-based computers only. Resetting the PS/2 on a target device running any other operating system may require that you reboot that target device.

If your PS/2 keyboard or mouse locks up, you may be able to re-establish operation of these peripherals by issuing a Reset command. The Reset command sends a hot-plug sequence to the target device that causes the mouse and keyboard settings to be sent to the DSR switch. With communication re-established between the target device and the DSR switch, functionality is restored to the user.

To reset the PS/2 mouse and keyboard values:

1.If the OSCAR interface is not open, press Print Screen to open the Main dialog box.
