7.8 Switch Mode:
The switch mode enables the unit to provide glitch free switching when a genlock signal
is available.
If the Reference is YES on RGBHV units, the unit will look at the current output signal
for the 1
st
vertical interval and then switch. If the output signal does not have vertical
sync, the unit will look at the 1
st
vertical sync input connector to synchronize the
switching.
In the Reference YES mode on Video units, the unit will switch on the 1
st
vertical interval
22 ms (milliseconds) after the switch command is received. If there is no genlock signal
available, the unit will wait an additional 22 ms and then switch.
In the Reference “NO” mode on RGBHV units, the unit will look at the current output
signal for the 1
st
vertical interval and then switch. If there is no sync signal available on
the output, the unit will wait 22 ms then before switching.
In the Reference “NO” mode on Video units, the unit will switch 22 ms after the switch
command is received.
To change the setting on the main menu screen, scroll up/down till SWITCH MODE is
displayed on the LCD, and then press
SELECT
. The matrix will display
REFERENCE_IN 1 on the top line and NO on the bottom. Use the up/down buttons to
toggle between YES and NO. Press ESC to save your current setting to non-volatile
memory and return to the main menu mode.
7.8 Output Protect
The output protect allows the user to protect selected outputs from being changed
inadvertently from the front panel, preset switching or from any other control input.
(Note: Protection must be removed to make any changes to an output.)
To protect an output, use the main menu mode to scroll up or down until
PROTECT
OUTPUT
is displayed on the LCD, then press
SELECT
. Use the up/down buttons to
display an output, then press
SELECT
to set protection on that output. Use the
SELECT
buttons to toggle between
PROT
and
UNPROT
. Changing the output (using up/down
buttons) saves the protection setting on the formally selected output. Pressing
ESC
returns to the main menu.
