4. Switching KVM-0407
KVM-0407 supports 3 methods to switch between computers: Push button, Hot
Keys and OSD. Due to refresh of the video and re-synchronization of the mouse
and keyboard signal, it will take 1-3 seconds configure time after each switching.
This is the normal operation that ensures the proper synchronization is
established.
Note:
The drivers for most USB devices (Mass Storage device, CCD Cameras, Scanners,
Card Reader, Printers, e.g.) are required to be shut down or follow the “Safely
Remove” command provided in Windows before you disconnect the device, or
else the system might be hanged. When you switch computers with the Port
Selection Switch, it is the equivalent of disconnecting the device. Therefore, if
you have peripheral devices (other than a second keyboard and mouse) connected
to these ports, you must be sure to shut down or safely remove the USB driver
for them before switching computers.
1. Manual Switch by push button:
You can switch to any other available active USB host connection by simply push
the appropriate switch button on KVM-0407. The LED will be lit to indicate
which port is currently selected.
2. Two Steps Hot Key Switch by keyboard:
You can switch to any available active USB host connection by using the three
steps Hot Key directly, instead of manually select by pushbutton. To send
commands to KVM-0407, must be pressed twice ( Step1 ). Then you can
press [1] to [4] (Step 2) to switch between ports. (Support PS/2 Keyboard only)
