Limitations

¾All switches used as slaves must be the same size (all 8 port).

¾Up to 8 slaves be connected to form a maximum system size of 64 ports.

¾Slaves 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.

¾All USB Wizard switches must be powered OFF during dip switch configuration.
