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 . This reference signal applies to all
switchers in the multi-switcher system and facilitates switching all
VS-162/VS-1616 series units simultaneously
To choose the MTX (SYNC from Matrix) setting 4 as the example in Figure
17 illustrates:
Connect the RS-485 terminal block connectors 5 between each switcher in
the multi-switcher system
Connect and set the video reference signal on one of the video units to
EXT (external sync) or INT# 1 (internal sync)
Set the video reference on the other video units to the MTX (SYNC from
Matrix) setting
