SYSTEM INTERCONNECTION -
continued
Inputs
Connect up to 12 SDI inputs to the 12
Serial Inputs
of the Switcher Mainframe. Sources can be
either video or key. If the system has the 24 input option fitted, all input connectors can be used.
Connecting to an Alternate Mainframe
Connect the 10 BASE T socket on the rear panel of the primary mainframe (adjacent to the Panel
10 BASE TX connector) to the Panel 10 BASE TX socket on the alternate mainframe.
Referencing
The Switcher can be Genlocked to any of its Inputs or to analogue sync on the
Ref Analogue In
loop-through connectors, selectable from the
Configure-System-Genlock & Outputs
menu.
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
Ω
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 sync output
with which to synchronise external sources.
Referencing - Input Timing
Since all inputs have framestore synchronisers, correctly positioned pictures will be obtained even if
the sources are free running. However it is recommended that the switcher and source are locked
together. This ensures constant video delay through the switcher and avoids missing or repeated
frames which will occur every time a source “runs through” a complete frame
There are two methods for referencing the switcher system.
(a) A common ‘station’ sync or black-burst reference is fed to all sources, and to the switcher. This
arrangement should be used when same sources are fed to other equipment apart from the
switcher. In this case switcher
Genlock
should be
On
, and the
Genlock H/V Phase
controls
adjust the timing of the switcher relative to the sources.
(b) The sources are referenced from the
Ref Sync Out
put of the switcher. In this case the timing
of the sources is set relative to the switcher by the
Sync H/V-Phase
controls. This
arrangement should be used if the switcher is the master reference in the system. It can also
be used when the output of the switcher needs to be timed into following equipment; in this
case the switcher will is genlocked to a ‘station’ sync or black-burst, and the
Genlock H/V Phase
will move the timing of the switcher output
and
the sources together.
These controls can be found in the
Configure-System-Genlock & Outputs
sub-menu.
Note: the Output Line-Standards must be correctly set before doing this.
