9.3 Configuring the Sync
On the VS-162V, you can select one of the following, as the sync input:
• EXTERNAL (“sync in” BNC connector)
• INPUT # 1 BNC connector
• MTX (Sync from Matrix) RS-485 terminal block connector, when
using multiple machines
1
Configure the sync via the SWITCHING METHOD menu command
setting
2
Usually, the easiest method is to choose the sync source from the first
machine (for example, the Y unit in a 16x16 YUV switcher configuration,
as section
. When setting up multiple machines (for example, a 48x64
switcher) or a 16x16 YUV switcher, linking a common sync to all the
machines may be necessary to facilitate simultaneous vertical interval
switching.
7.2.2 describes) and then connect all the terminal block
connectors, as
Figure 7 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 15 and Figure 16 illustrate. Select the MTX sync on the other
machines that receive that sync.
9.4 Connecting the KEYBOARD EXTENSION
Connecting dry contact-closure switches to the Keyboard Extension (EXT.
KEYS) connector enables you to route an input to an output by remote
control from a distance of up to 1000 meters. These IN and OUT keys are
expandable

Figure 18. shows how to connect the Keyboard Extension
(EXT. KEYS):
1 Refer to section 11.5.1
2 Refer to section
11.5
3 Add an unlimited number of push buttons to the existing keys (in parallel) by attaching one end of the push button to the
corresponding number and the other end to the IN or OUT
