SINGLE-HEAD MODE KM SWITCHING
In addition to traditional channel switching by buttons located on the front panel, KM also supports cursor
control of selected channels. This technology allows seamless switching between computers by moving the
mouse cursor from one display to another. Users can effortlessly switch computers for faster productivity.
1. KM functionality for KVM devices is only available once the device has been put into KM mode,
refer to admin tool guide for detail.
2. When the device is placed into KM mode, it will behave identically to the KM models of the product.
3. The major difference when the device is placed into KM mode is that cursor control of selected
channels is available as an additional method to switch the connected computer.
4. Figure 10-1 below shows how this functionality works.
