Physical Interface Cascading:
Physical Interface Cascading refers to cascading to a second stage KVM switch (such
as the Altusen KH0116) that doesn’t utilize the same protocol as the first stage
KM0432, but uses the same physical interface (PS/2 or USB ports, for example).
The advantage of cascading to a switch like the KH0116 is that it yields
enormous expansion capability. Since it can be daisy chained to 31 additional
KH0116s, up to 16,384 computers can be controlled from a single KM0432 (32
KM0432 ports x 32 KH0116s x 16 ports per switch = 16,384 ports).
The operational difference between this method and Protocol Interface
Cascading is that since the OSD protocols are not the same, the OSDs of the
cascaded KH0116s cannot be integrated. Unlike Protocol Interface Cascading,
the OSD that the operator works with is the OSD for each particular KH0116 -
not an OSD that incorporates all of the switches on the installation.
Therefore, in order to access a computer connected to a particular KH0116, the
operator must first bring up the KM0432’s OSD to access the target KH0116.
He then activates the KH0116’s OSD to accesses the target computer.
In this type of installation, the KM0432 is considered the First Stage unit; the
KH0116 is considered the Second Stage unit. If there are additional KH0116s
daisy chained down from the Second Stage KH0116, the entire chain is seen as
a Second Stage unit, with the top level KH0116 (the Master switch) as the OSD
access point for the entire chain.
To set up a Physical Interface Cascade, refer to the installation diagram on p.
23, and do the following:
1. Make sure that power to all the devices you will be connecting up has been
turned off.
2. Use Cat 5 cable to connect any available CPU Port on the First Stage unit
(the KM0432) to a PS/2 style KVM adapter cable (as described in the
Cables section, p. 4); plug the adapter cable’s KVM connectors to the
Keyboard, Video, and Mouse Console ports of the KH0116.
Note: The distance between the Second Stage unit and the KM0432 must
not exceed 150m (500’).
