Trouble Shooting

1. Power LED is not lit

  • Check if the power adapter is properly connected to the power outlet and the CPU Switch.  Make sure the power switch on the unit is turned ON.

2. No screen display after the PC is powered on or after switching channel

  • Press the SELECT button to switch to a port with PC connected.
  • Make sure the monitor is firmly plugged into the console connector.
  • Make sure the cables are firmly plugged into the PC port connectors.
  • Try different video resolution by adjusting the setting of the display controller card from the Windows control panel.

3. Lost mouse control

  • Do not move the mouse during the switching.  CPU Switch can not switch the mouse control when it is still receiving the mouse signals.
  • Make sure the mouse is firmly plugged into the console connector.
  • Make sure the cable is firmly plugged into the PC port connector and the PC.
  • Do not use AT to PS/2 or PS2 to AT mouse adapter.
  • Do not unplug and plug the mouse without shutting down your PC first.
  • For CAS421 which supports mouse translation, connect only PS/2 mouse to the console.  Also do not connect both PC's serial and PS/2 mouse ports even though your PC may support both.
  • For CAS221 which DOES NOT support mouse translation, only PS/2 mouse connected to console port will control the PCs' PS/2 mouse port and AT mouse connected to console port will control the PCs' AT mouse port.  You must connect both PS/2 and AT mouse to console ports if you plan to control one PC's PS/2 mouse port and the other PC's AT mouse port.   Do not connect both PC's mouse ports even though your PC may support both.

4. Lost keyboard control

  • Do not type any key on the keyboard before the channel is completely switched to new channel as indicated by the change of display screen.
  • Make sure the keyboard is firmly plugged into the console connector.
  • Make sure all the cables are firmly plugged into the PC port connectors.
  • Make sure the unit is not in automatic scan mode.
  • Try to switch to another channel and switch back.
  • For model CAS421, do not connect both AT and PS/2 keyboards to the console keyboard connectors.

5. Wheel mouse does not function properly

  • Make sure you have loaded wheel mouse driver.
  • CPU Switch  supports only Microsoft PS/2 Intellimouse driver.

6. Push button does not function properly

  • Do not hold the button for more than one second if you are switching channel.
  • Hold the button longer than one second if you want to activate the Scan mode.
  • Push the center of the button to ensure accurate switch mechanism.

7. Mouse and keyboard do not respond instantly after channel switching

  • Do not move the mouse the mouse or typing keyboard before the CPU Switch complete the channel switching.  If the CPU Switch detects mouse or keyboard signals input from current channel before the switching is complete, it will delay the channel switching until there's  no more signal input.  In such case, you will feel slight delay in the response of mouse pointer or keyboard.  Stop moving the mouse or typing the keyboard, and the CPU Switch will complete the switching immediately.

8. Unable to switch channel

  • If you are using Hot Keys, make sure "CTRL", "ALT" and "SHIFT" keys are pressed simultaneously and follow with a valid digit number and "Enter".
  • If you are using push button, make sure push the center of the button to accurately initiate the switching.
  • For CAS221, do not move the mouse or typing keyboard before the CPU Switch complete the channel switching.  The monitor will not switch until no more mouse or keyboard signals are detected.
