Connection
Before connecting a device (a computer or a Slave) to the Master KVM, you
must turn off them. The Master can be a any model and you just put one
OSD KVM to the Master and Non-OSD for the Slave, then all cascade
system will become full OSD function operating.
The ports labeled "
a Slave's CONSOLE port, as shown in figure 9. A power adapter with DC
9V/500mA output rating must be connected to the Master.

Figure 9: Slave console connection
The maximum number of computers controlled by a master/slave
configuration with all 4-port switches is 64 with 16 Slaves and each Slave
connects to 4 computers, see figure 10. For an all 8-port switch
configuration, the number is 512 with 64 Slaves and each Slave connects to
8 computers, see figure 11. If a 16-port is a Master, the maximum capacity is
4096, see figure 12. The Master connects to 256 Slaves ( PC 1 to PC 16),
and each Slave connects to 16 computers.
If the Master is already OSD-equipped, all the Slaves are not OSD requir ed.
This is the extra saving of using this line of KVM switches.
