Belkin P72114 Technical notes on specific devices IBM ThinkPad, Contacting Belkin Components

•The OmniView PS/2 supports either PS/2- or AT-style (serial) mice. Note that the OmniView does not convert from one type to the other. If you wish to use PS/2 mice on some PCs and serial mice on others, you must attach two mice, one of each type, to the console port on the top-level OmniView. This allows control of multiple computers from one monitor, one keyboard, and two mice.

Q:The mouse is not detected upon boot-up or the mouse is lost or acts erratically when switching ports.

•Check all cable connections.

•Do not move the mouse when switching and also give it a second or two after switching before moving the mouse.

•Check DIP switch settings. All should be ON except switch 3 to use a non-cascaded OmniView.

•Check the mouse driver, it should be the same as the type of mouse attached to the OmniView.

•Make sure you are using the correct power supply, it should be 9VDC 600mA.

•If you are using Windows95 or Windows3.1, remove any unnecessary mouse drivers from DOS configuration files (config.sys and autoexec.bat).

•If the problem continues, try a different mouse.

•Boot up the computer with the its port selected on the OmniView

Technical notes on specific devices:

IBM ThinkPad:

•IBM ThinkPads use a proprietary interface for keyboards and mice, which may cause the mouse not to release from the port the ThinkPad is connected to. There are several solutions to this problem:

1.Use a serial mouse to control all the computers, including the ThinkPad.

2.Use a dedicated mouse for the ThinkPad, either PS/2 or serial will work fine.

3.Disable the built-in pointer on the ThinkPad.

4.If you have the ThinkPad on one port on the OmniView and you are using a PS/2 mouse, you may have to do the following: Select a port the ThinkPad is NOT on. If mouse control is lost, “tap” on the ThinkPad’s pointing device, and mouse control will be regained for that computer.

IBM ValuePoint Computers and 2-port OmniViews:

•With IBM PS/2 ValuePoint computers, when booting the computer, a PS/2 pointing device error may occur. Again, IBM PS/2 ValuePoint computers seem to be using a specific interface that causes this. To solve this, pin 6 on the keyboard extension cable will have to be cut or bent off. This is only on one end of the PS/2 male to male keyboard extension cable. Pin number 6 is the pin to the right of the black plastic tab. This is when the black tab is facing up at a 12 o’clock position.

Microsoft Intellimouse (the mouse with the wheel):

•Using this mouse can sometimes cause erratic mouse movement or loss of the mouse when switching ports on the OmniView from one computer to another. The solution for this is to not move the mouse when switching and also give it a second or two after the switch is made. Reasons for this reaction is still not known.
