D-Link DKVM-4 Product Manual - Page 11

The computers boot properly but I cannot use the mouse. What can be the cause? One of the following may be the case: § Please verify that the mouse is plugged into the DKVM-2/4 unit properly. § Make sure the mouse works properly when plugged into a computer directly. You will need to reboot the system to test this. § Try using a different mouse. § Verify that the mouse complies with the PS/2 standard. A combination mouse will work, but it must be set to PS/2 mode and the correct serial mouse to PS/2 adapter must be used. A serial mouse with a serial - PS/2 adapter will not work, since the mouse signals do not comply with the PS/2 standard. § Make sure that the power adapter is plugged in at both ends and that it is working correctly. Its rating must be 9V 600mA. When I switch between computers, mouse movement becomes random. What can be the cause? One of the following may be the case: § Verify that your computers do not have more than one mouse driver installed. Make sure that the driver is for a standard PS/2 or fully Microsoft compatible PS/2 mouse. Also check with the mouse vendor to verify you are using the latest mouse driver. § Check your config.sys and autoexec.bat files (if you run Windows that is) and verify that only one mouse driver is loaded. § If a special mouse is used, such as a cordless or scrolling mouse, make sure you use generic PS/2 mouse drivers. A nonstandard PS/2 mouse may have extensions on the PS/2 protocol that are not supported by the DKVM-2/4 unit. § Do not move the mouse or press any mouse buttons while switching from one system to the other. § Try resetting the mouse by unplugging it from the DKVM-2/4 unit for about 3 seconds. Mouse movement will now be correct again. 9
