2.2 Checking Status
Status is constantly displayed in the crosspoint LEDs for the
active level. If your levels have different I/O configurations,
check the status of one level at a time.
To check status for one level, activate it by selecting its Level
key. The LED above the selected key should illuminate. The
crosspoint LEDs also illuminate to display the level’s I/O
configuration.
2.3 Locking Out Control Panel Switches
Locking out control panel switches maintains the current I/O
configuration while preventing new switches from occurring
through the X/Y Control Panel. When the control panel is
locked, status is not displayed.
To lock out control panel switches:
Turn both levels off by pressing each Level key until the LED
above it is off.
To unlock the control panel:
Activate a level. The LED above the active level’s key
illuminates.
2.4 Switching During the Vertical Interval
The sync processor can accept a sync pulse or strip the sync
pulse from a composite video signal. If a sync pulse is not
detected within 1/30th of a second from a switch command
switching will occur by default.
Attaching a video signal connector to the sync connector
enables the sync processor. To use a video signal as the sync
signal as well as a usable input signal, split the signal and
attach it to both the sync connector and a video input
connector.
