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

2 Item 3 in Figure 2
3 Item 5 in Figure 2
4 This sets the matrix sync configuration from another (Master) machine
5 Via a straight connection of all 4 PINS
