Chapter 20 Switcher Setup (Switcher)
1062
Interfacing With External Devices (Device Interface Menu)
Notes
• “Level Enable” is a function that determines whether GPI inputs are enabled
(“Enable”) or disabled (“Disable”) for the “Aspect” and “Format” actions
that can be used when the trigger type is Level. When Level Enable is used,
if the input is “Disable” then it is not possible to switch “Aspect” or “Format”
by GPI input.
If a GPI to switch “Aspect” or “Format” occurs when powering the system
off, the action triggered by the GPI may start immediately before the power
goes off and the power may go off before the action is completed. This may
corrupt the setup settings. It is therefore recommended to use Level Enable
to avoid such a situation.
• If “Format” is selected for “Action” when the format converter is used on the
switcher, you can set the conversion formats of the format converter for “FC
Input 1-8”, “FC Input 9-16”, “FC Output 1-2” and “FC Output 3-4”.
Carrying out level settings
To set the low level and high level, first set the trigger type to “Level,” then use
the following procedure.
1
In the Switcher >Device Interface menu, select the action to be set, and
press [H/L Set].
The H/L Set menu appears.
2
Using any of the following methods, select the settings.
• Press directly on the list in the status area.
• Press the arrow keys to scroll the reverse video cursor.
• Turn the knob.
3
To apply the selection made in step 2 when the input is high, press [H Set].
To apply the selection made in step 2 when the input is low, press [L Set].
This confirms the setting, which appears in the status area.
Notes
• When the action is “Format,” these settings conflict with the current
settings, but after making the settings, agreement is restored after a pulse
change or power off/on.
• When the Action is “Bkgd A Side Flags” or “Bkgd B Side Flags,” the
levels are fixed, as follows.
High level: Off
Low level: On
