Two pair of loop-thru BNC coaxial connectors, illustrated in Figure 3-24, provide interface for two,
sources of house synchronization signals (Analog Only - i.e. NTSC, PAL, 1080i, 1080P, and 720P).
Each house sync input is a pair of BNC connectors wired in parallel (1 and 3 are a pair; 2 and 4 are a
pair) allowing the external synchronization signal to be daisy-chained through the 864XR frame.

Using the system control software, such as PERC2000, 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:
