6.5 Configuring the Sync
You can configure the method of the switching between the video sources in
the VS-3232V. The switching (transition) is done according to the selection of
the SYNC input:
An EXTERNAL Sync (the GENLOCK BNC connector)
The INPUT # 1 BNC connector, or
An EXT-SYS SYNC 1 (a sync derived from another 32 or 16 series
switcher) via the RS-485 sync Terminal Block connector 2
You can also set the machine to the immediate switching mode, in which
switching is executed immediately after receiving the command. This mode is
not a glitch-free transition
Configure the sync via the SYNC Configuration Menu command setting 3 .
When setting up for example, a 32x32 YUV switcher, linking a common sync
to all the machines may be necessary to facilitate simultaneous vertical
interval switching.
Usually, the easiest method is to choose the sync source from the first
machine (for example, the Y unit in a 32x32 YUV switcher configuration, as
section 6.2.2 describes) and then connect all the terminal block connectors 4 , as
Figure 10 illustrates.
In this case, set the first machine to select the sync source from the external
sync connector or from the INPUT # 1 connector. This sync is now available
to the other machines via the RS-485 terminal block connector, as Figure 8,
Figure 9 and Figure 10 illustrate. Select the EXT-SYS SYNC 5 on the other
machines that receive that sync.

receiving the command. This mode is not a glitch free transition
