If connection succeeds, the plug icon changes status to connected plugs.

Check the ‘Has focus knob’ for automatic read back of position.

The movement direction determined by the up/down buttons can be reversed by checking the 'Host Direction' check box.

The movement direction determined by the focus knob can be reversed by checking the 'Knob Direction' check box.

The tools drop down shows the temperature and power supply of the controller.

The Standby and Running currents can be set.
