Extron electronic MGP 464 HD-SDI manual Additional Features, Freeze mode, Resetting

PRELIMINARY

Operation, cont’d

NThe 128 input presets are global, containing all of the settings for an input when the MGP is used with a matrix switcher. This allows a matrix switcher with multiple types of video inputs to be connected to the MGP 464 to expand the number of input video sources.

Each input should be switched into the MGP, configured (window/image sizing, position, color, tint, brightness, contrast, and text label), then saved as a preset for recall by the control system when that input is sent from the switcher to any of the four MGP inputs.

Additional Features

Freeze mode

The front panel Freeze button is the first button on the left. Press this button to freeze the current image in the currently selected window. You can also freeze the windows using the Windows-based control software or SIS commands via an RS-232 or RS-422 connection.

If you switch inputs while a window is frozen, the freeze mode is cancelled and the new input’s image appears in the window.

Locking the front panel (executive mode)

To prevent access by unauthorized users or accidental changes to the MGP 464’s

settings, some of the front panel controls can be locked using executive mode. When you place the MGP in executive mode via the front panel, the picture control buttons and the menu selection buttons are locked. All other functions (input and window selection, freezing, and preset saving and recalling) remain accessible. The rear panel RS-232/422, front panel Config, and LAN ports also remain unlocked.

You can enable or disable executive mode when the system is in the default cycle. To turn executive mode on and off, press the Window/Image Size and the Window/Image Position buttons simultaneously, and hold them for at least 2 seconds. The default is Disabled.

You can also enable and disable executive mode by using the SIS commands or the Windows-based control software via the serial or LAN ports (see chapter 4, “Software Configuration and Control,” for more information).

NIf you place the MGP in executive mode by using SIS commands or the Windows-based control software, you have an additional type of executive mode available. In executive 2 mode, all the front panel controls are locked. This mode is available only through SIS commands. See chapter 4, “Software Configuration and Control,” for information on SIS commands, or the control software’s help program.

Resetting

Resetting the unit causes various IP functions and Ethernet connection settings to revert to factory defaults. There are four reset modes (numbered 1, 3, 4, and 5 for the sake of comparison with Extron IP Link products) that are available by pressing the Reset button on the rear panel. The Reset button is recessed, so you must use a pointed stylus, ballpoint pen, or small screwdriver to press it. See the table on the next page for a summary of the reset modes.

CReview the reset modes carefully. Using the wrong reset mode may result in unintended loss of flash memory programming, port reassignment, or processor reboot.
