machine, for example, the VS-162V switcher (as
, you can select as
the sync input, the MTX (Sync from Matrix) RS-485 Terminal Block
connector. For example, a video-audio switcher (using VS-162V and
VS-1616A), linking a common sync to all the machines may be necessary
to facilitate simultaneous vertical interval switching.
Figure 21 illustrates)
and then connect all the terminal block connectors.
In this case, set the VS-162V switcher 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 15 and Figure 16 illustrate. Select the MTX sync on
the VS-1616A switcher that receives that sync.
