Locking And Unlocking The Front Panel; Setting Rgb Delay; Using Genlock Sync - Extron electronics MPX 423 A User Manual

Locking and Unlocking the Front Panel

Front panel security lockout prevents accidental switching of inputs from the front panel.
When front panel security lockout is active, the user can only view the ties in each group; all
input buttons and audio functions are locked.
To toggle the front panel lockout on and off, press and hold the I/O button for three
seconds. The Video and Audio LEDs flash twice to indicate a change in the front panel
security status (on or off).

When front panel lockout is on, the user can still view the ties by toggling the I/O and
output buttons. The LEDs of the corresponding inputs light according to their tie modes.
If you attempt to make a tie in lockout mode, the Video and Audio LEDs flash twice,
indicating that no ties can be made from the front panel. RS-232 and Ethernet controls are
still available when the front panel is locked.

Setting RGB Delay

The RGB delay feature clears the screen during transition to a new input source, which
prevents a visible glitch from occurring on the output screen. RGB delay can be set between
0 and 5.0 seconds in 0.5 second increments.
To use the front panel to set an RGB delay:
1. Select the desired output (1 or 2).
2. Press and hold the I/O and Mute buttons simultaneously for three seconds. The Video
LED and the currently selected Output LED begin flashing.
3. Turn the Volume knob clockwise to increase delay time. Input LEDs 1 - 10 light one
at a time as the Volume knob is turned clockwise. Each lit input LED represents a
0.5 second delay. When RGB delay reaches its maximum of 5 seconds (LEDs 1 through
10 on), the Mute LED blinks.
4. Press the I/O button to exit.

Using Genlock Sync

The genlock sync feature locks the sync generators of multiple devices to a single source
which prevents visible glitches from occurring on the output screen during transition to a
new input source. The source at input 5 provides the genlock sync signal to all of the Video
group inputs. The source at input 9 provides the genlock sync signal to all of the S-Video
group inputs. This happens automatically when inputs are connected to inputs 5 and 9. No
configuration is required.
