2.4. Connect Your PCs and Peripherals to 

Multiple Daisy-chained KVM Switches 

If you use only a single KVM Switch and hence have no need for cascaded application of 

multiple KVM Switch units, just skip this section. 

 
To add port capacity, multiple 

UKV-048OSD/UKV-088OSD/UKV-0168OSD

 KVM 

Switches can be cascaded in a daisy-chain configuration to maximize the number of 
connected computers up to a total of 256 computers (with 16 units of UKV-
0168OSD KVM Switches). This cascaded application is obviously advantageous 
when groups of computers are dispersed and with some considerable distance from 
each other. Each cascaded KVM can be away from the next KVM Switch up to 30 
meters (dependent on your cable type)

,

 thus expanding the applicable distance of 

only one single KVM switch yet with the convenience of centralized control by one 
master KVM unit. Control commands can then be extended to groups of computers 
on the master KVM Switch on remote end through this daisy-chain connection.

 

The KVM Switch units that are to be daisy-chained do not have to be of the same port 

capacity. In fact, you can daisy-chain different units with different port capacity as to scale the 

total port capacity more flexibly.
