after which it does not have to be connected to the computer.
If your system is expanded beyond four Plug 'n Power modules, you
may find it inconvenient to re-connect the Controller to the computer to
manually control your lights/appliances. You may also wish to control
your modules manually from several locations. For this reason you
may wish to purchase an additional manual controller such as Cat.
