Parameters Function of the Command Syntax
Example: UDTL RESET
– reset Toggle Left User Defined Strings
DELETE
Deletes the user defined string index specified by the ID number.
Example: UDTR ID=0 DELETE
– delete Toggle Right String index number 0
Note: The UDRE Command deletes the current User Defined Switch assignments from the Saveset
database.
3.12.1.1 Example 1: Toggle Switch Control of PiP Window Functions
This example will use User Defined Commands to:
1) Configure the Toggle Switch left position to move the PiP window clockwise around the outside corners of the
display.
2) Configure the Toggle Switch right position to turn OFF and ON the PiP display by disabling and enabling the
SDI 2 video path.
' set the Toggle Left switch functions to reposition PiP placement
UDTL ID=0 "PP2 BR" ' set PiP window 2 to Bottom Right corner
UDTL ID=1 "PP2 BL" ' set PiP window 2 to Bottom Left corner
UDTL ID=2 "PP2 TL" ' set PiP window 2 to Top Left corner
UDTL ID=3 "PP2 TR" ' set PiP window 2 to Top Right corner
' set the Toggle Right switch functions to enable/disable PiP display
UDTR ID=0 "VSD2" ' Disable the SDI 2 video path
UDTR ID=1 "VSE2" ' Enable the SDI 2 video path
Notes:
1) If there is a gap in the ID numbers, the Toggle Switch will wrap at the gap. (For the syntax of the PiP
Command,, see Table 14: PiP Size & Position Command Syntax.)
2) The VSD and VSE Commands are defined in Table 20: Miscellaneous Video Path, Status & Report Control
Port Commands.
3) To display the saved Switch settings, use the REU Command per Table 27: Miscellaneous Control Port
Commands
4) If the DX-4400 is switched to the DUAL TI mode without changing the Saveset database, the VSD2
Command in the above example will disable the SDI 2 Output if the Toggle Right switch is activated.
Warning: These Switch definitions will be retained even if the unit is re-configured for another Mode of
Operation. Therefore, if this example was applied and later the mode of operation is changed, the SDI
2 input will be disabled/enabled by the Toggle Right switch assignment in the new mode of operation.
3.12.1.2 Example 2: Toggle Switch Control of ARM Graphics Overlay Fields
The following two User Defined Command string examples (see Commands listed in Table 24 ) will configure the
Toggle Switch to turn the ARM Graphics Overlay ON and OFF using the VADn Disable and VAEn Enable
Command (See
Table 27 ).
For example, the following User Defined Command strings will assign a Command String Index to program the
Toggle Switch left and right action to disable and enable all Fields (text, graphics and images) assigned for
display on the ARM Graphics Overlay video stream.
UDTL ID=0 "VAD1"
UDTR ID=0 "VAE1"
