8.3 Choosing the SWITCHING METHOD Setting
Section 8.3.1 describes the SWITCHING METHOD settings for stand alone
units and large matrices. Section 8.3.2 describes how to configure a
SWITCHING METHOD.
8.3.1 Understanding the SWITCHING METHOD Settings
Setting the unit as a Stand-Alone UNIT provides a choice of 3 SWITCHING
METHOD settings:
• NoVIS - switching occurs immediately after completion of front
panel or dry-contact operation or immediately after receiving an RS-232
or RS-485 command, or an IR command. The switching is independent
of the vertical reference
• EXT (external sync) - switching occurs during the vertical interval
of the video reference signal connected to the IN SYNC 1 connector (this
signal should be properly terminated via the TERM button 2
• INT# 1 (internal sync) - switching occurs during the vertical interval
of the video reference signal connected to IN # 1
)
Setting the unit as a Large Matrix (instead of as a Stand-Alone UNIT) provides a
choice of 4 SWITCHING METHOD settings:
• NoVIS, EXT or INT# 1 (as described above)
• MTX (SYNC from Matrix) - the vertical interval of the video
reference (selected on one unit in the Large Matrix system) is present on
the “SYNC” RS-485 terminal block connector 3
To choose the MTX (SYNC from Matrix) setting
. This reference signal
applies to all switchers in the multi-switcher system and facilitates
switching all VS-162/VS-1616 series units simultaneously

as the example in
illustrates:
• Connect the RS-485 terminal block connectors 5
• Connect and set the video reference signal on one of the video units
to EXT (external sync) or INT# 1 (internal sync)
between each
switcher in the multi-switcher system
• Set the video reference on the other video units to the MTX (SYNC
from Matrix) setting
