AdderView Installation and Use Page 34
Appendix B. Problem Solving
Problem:
Poor video quality with smearing fuzziness or ripple.
Action:
Use screened coaxial video cables to connect your devices to the AdderView.
Problem:
Mouse does not move cursor on screen.
Action:
Ensure that the mouse and computer are both connected to AdderView before
power is connected and ensure that the AdderView is powered on before the
attached computer. Ensure that your software is configured to accept a Microsoft
compatible mouse of the type that you have connected (PS/2 or RS232). If you
move the mouse and the activity indicator (dot on 7 segment display) does not flash
then the AdderView is not receiving data from the mouse. Check the mouse
connection to the AdderView, try resetting the mouse using the reset function
(section 3.3) or re-powering the AdderView. If you are attempting to connect the
AdderView to a CPU with a PS/2 mouse connection that has not been powered
down then you will need to use the mouse restoration functions F5 or F6 (see
section 2.9).
Problem:
Keyboard does not function or functions intermittently. Num lock light does not
always come on when the num lock key is pressed.
Action:
Some older keyboards were designed for use with specific computers and are not
truly AT or PS/2 compatible. These are not common but if you experience problems
try another keyboard.
Problem:
Mouse causes channel to change.
Action:
Some cheaper mice are not fully compatible with the AdderView and can lose data
causing the channel to be changed (if mouse switching of channels is enabled). If
you experience this problem then change the mouse and use a Microsoft, Logitech,
IBM, Compaq or Hewlett-Packard type. Ensure that you are using a Microsoft
compatible mouse driver on your PC. Some other manufacturers’ drivers may switch
