8.5 Choosing the SWITCHING METHOD Setting
Section 8.5.1 describes the SWITCHING METHOD settings for stand alone
units and large matrices. Section 8.5.2 describes how to configure a
SWITCHING METHOD.
8.5.1
Understanding the SWITCHING METHOD Settings
Setting the
VS-1616V
unit as a Stand-Alone UNIT
1
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
2
connector (this signal should
be properly terminated via the TERM button
3
)
INT# 1
(internal sync) - switching occurs during the vertical interval of
the video reference signal connected to IN # 1
Setting the
VS-1616V
unit as a Large Matrix
1
(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
4
. This reference signal applies to all
switchers in the multi- switcher system and facilitates switching all
VS-1616V
units simultaneously
To choose the MTX (SYNC from Matrix) setting
5
as the example in Figure
21 illustrates:
Connect the RS-485 terminal block connectors
6
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
1 Via the MACHINE ADDRESS setting (as section 8.4 describes)
2 Item 1 in Figure 2
3 Item 3 in Figure 2
4 Item 5 in Figure 2
5 This sets the matrix sync configuration from another (Master) machine
6 Via a straight connection of all 4 PINS
