Using the Cheetah GUI, the user can assign a specific reference signal for the system or
individual chassis that is used as a synchronization signal for specific output synchronized
switching. Once the output has been switched, the output signal remains synchronized to the
initial reference assignment until it is switched again with a new reference assignment. An
example of a sync assignment would be as follows:
Reference 1 is connected to an NTSC sync signal source and Reference 2 is connected to a
PAL sync signal source. Using the GUI, the user assigns Reference 1 to outputs 6 through 10
and Reference 2 to outputs 11 through 16 for a specific chassis.
Reference 1 or 2 should be connected to the house sync source or tri-level source with coaxial
cable and standard BNC connectors.

Chassis Level Codes (Strobes) assign operational parameters to the switcher frame. There are
seven rotary switches, located just to the right of the power supply modules and accessible from the
front of the router, used to set the chassis level code and other frame operational characteristics.
Chassis switch settings are preset at the factory and should never need any maintenance or
adjustment. This information is provided as a reference so that in the event any switch setting
should inadvertently be changed, it can be restored to its correct setting.
Proper setting positions for these switches are shown in Figure 4-19.
Prior to adjusting any of the chassis strobe switches, it is strongly
recommended that you contact PESA’s Customer Service Department for
assistance.
