MGP 464 • Operation 3-26
PRELIMINAR
Y
N The 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).
N If 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.
C Review the reset modes carefully. Using the wrong reset mode may result
in unintended loss of flash memory programming, port reassignment, or
processor reboot.
