Operation, cont’d
Front Panel Security Lockout (Executive Mode)
When front panel is locked, the front panel input and Configuration buttons' functions are blocked. To toggle the front panel lock on or off, press and hold down the Output and Configuration buttons for more than 3 seconds. All LEDs flash to indicate that the command has been accepted.
NWhen the front panel is locked, you still can view the tied inputs by pressing the Outputs button to toggle between the selection of output 1 and output 2.
Genlock Sync
When switching between inputs, the resulting image change should be seamless and clean. The MMX switchers reference the external sync signal on input #1 to synchronize switching during the vertical interval. This allows vertical interval switching between genlocked sources. Without the external sync locking feature, switching between inputs can result in a brief rolling (sync loss) or a brief change in the picture size.
System Reset
To reset the unit to factory defaults, press and hold the Config button while power is applied. This resets the audio input settings to unity (0 dB) and connects input 1 to outputs 1 and 2, audio and video. The audio and video Config LEDs are lit.
