master’s “KEY 1” port (see Fig. 15 below and the chart on page 7).
e.
Repeat steps c and d for each additional slave unit, keeping in mind that each slave will connect into the next available
master’s port (i.e. slave #2 to master’s “VIDEO PC-2” and “KEY-2”, etc.).

R e p e at step g. until all slave units are connected together.
i.
Repeat the installation section of the manual for any CPUs to be connected to the master.
