In our last blog post, we’ve explained the name of our KVM extenders DVIVision-MC4-ARU2-CON and -CPU. Today, we will show you how many CAT cables you will need to connect the user module and the computer module of the extender system.
Required number of CAT cables depends on MC variant
A USB 2.0 port always requires an individual CAT line due to the high bandwidth of the data. Actually, the bandwidth is so high the remaining four CAT lines are not able to carry the additional data without any interruptions.
When applying extender systems supporting USB 1.1, the CAT lines transmit USB and KVM signals on one line. Here, the number of CAT lines varies depending on the KVM extender system in use. However, you won’t always need four CAT cables (plus one line for USB 2.0) to connect the user module with the computer module. In general, you will need one CAT cable for every video channel you want to connect.
Here’s an example:
Connecting DVIVision-MC2-U-CPU and DVIVision-MC2-U-CON requires two CAT lines. Since the KVM system in this example supports USB 1.1, you will need only two cables to connect the modules.
Unfortunately, there isn’t a general rule for the number of CAT cables required to connect user and computer modules. Just remember that the most important aspects are the type of USB port and the multi-channel variant in use.
