Switching mode
The switching modes available are Frame, Field or Immediate. These switching modes are
effective with either a manual switch or automatic switch. In Immediate mode the Smart
Switch 3G will act immediately but this untimed ‘crash’ switch is likely to cause a picture
disturbance. Selecting either Field or Frame under non-catastrophic error conditions will allow
the Smart Switch 3G to switch away in a tidier manner, assuming that the two inputs are co-
timed.
Switch back
Once a switch has taken place, automatic switch back will be controlled by the switch back
control. Immediate mode will allow the switch to return once the error has disappeared for at
least one frame. In certain circumstances this could result in the output flip-flopping between
the two inputs erratically. To avoid this, the switching action can be either delayed or latched.
GPI configuration
The GPI inputs can be used to control input selection/routing and are configurable for either
edge or level trigged. They can also be used to give a tally of the selection/routing. When GPI
control is selected to ‘level’, GPI = High (floating) selects Input 1 and GPI = Low (pulled to
ground) selects Input 2.
See page 7 for information on the GPI modes which can be selected.
