Figure 7- Master-to-Slave Device Cable Connections
Limitations
¾ All switches used as slaves must be the same size (all 8 port).
¾ Up to 8 slaves be connected to form a maximum system size of
64 ports.
¾ Slaves must be added to the master in order (slave #1 to master’s port 1, slave #2 to master’s port 2, etc).
Note: Master Port 1 (with an 8-port Slave connected to it) will become ports 1-8. Master Unit Port
2 (with a second 8-port Slave Unit connected) will become port numbers 9-16.
¾
All USB Wizard switches must be powered OFF during dip switch configuration.
These switch settings (Table 2) enable the slave to
establish its identity (i.e. location in the group) to the
Master.
Side Note: In a Master, the same switches are used to
configure the Master for how many slaves are attached
to it.
