SYSTEM TIMINGS
Referencing
The Switcher can be Genlocked to any of its 12 HD-SDI Inputs or to tri-level sync. on the
Ref
Analogue In
loop-through connectors, selectable from the
Configure-System-
Genlock & Outputs
menu (see User Manual).
Note that the input number set in this menu is
absolute and is not remapped through the
Configure-User-Source Mapping
menu.
If the incoming reference signal is not used elsewhere then the remaining
Ref Analogue In
BNC
should be terminated with a 75

terminator.
Whether the Switcher Mainframe is acting as the Master SPG for the system or is being Genlocked
to an external source, the
Ref Sync Out
BNC provides an adjustably-timed analogue tri-level sync.
output with which to synchronise external sources.
Referencing - Input Timing
To obtain correctly positioned pictures, all sources must be timed within a window that is 131072
74.25MHz or 74.25/1.001MHz clock periods wide. The table below shows how many milliseconds
and lines this equals in the currently-supported line standards.
Timing the sources can be achieved by adjusting (a) the
Genlock H/V Phase
controls (when the
switcher is not the Master SPG), (b) the genlock controls of the source equipment, and/or (c) the
Ref Sync Out
put’s
Sync H/V-Phase
controls. These controls can be found in the
Configure-
System-Genlock & Outputs
sub-menu, see User Manual
Note: the Input and Output Line-Standards must be correctly set before doing this.
