About Table 2:

These switch settings are used by the slave(s) to establish its identity (i.e. location in the group) to the master.

On a master, the same switches are used to configure the master for how many slaves are attached to it.

Cascaded Installation

1.Attach all slaves consecutively to the master switch.

a.Perform steps 1 and 2 under INSTALLATION on page 4 for each slave unit.

b.Configure each switch as per the tables above under CONFIGURATION before proceeding.

c.With a VEXT-xx-MM cable, connect slave #1 monitor port to master’s VIDEO 1 port.

d.With a VVKINT-xx-MM or (2) VKEXT-xx-MMs, connect slave #1’s PS/2 DEVICES ports to the master’s CPU1 KEYBOARD and MOUSE ports.

e.Repeat steps c and d for each additional slave unit, keeping in mind that each slave will connect to the next available master’s port (i.e. slave #2 to master’s VIDEO 2 and CPU 2 KEYBOARD and MOUSE, etc.). See Fig. 6 below.

If additional 4-PORT slaves are connected to VIDEO, PS/2 MOU CPU, & PS/2 KBD CPU ports 3 & 4, they will function and be controlled as CPU ports 9-12 and 13-16 respectively.

- OR-

If individual CPUs are connected

to ports 3 & 4, they will function and be controlled as CPU ports 9 & 10 respectively.
