Front Panel Operation
The functions of the front panel controls are described in the following sections.
Input selection
The four numbered Input selection buttons (1 – 4) will select from among the 4
separate input sources:
Input 1 : selects either a composite video or S-video input
Input 2 : selects either a composite video or S-video input
Input 3 : selects a composite video input
Input 4 : selects a composite video input
The Input buttons correspond to the numbered input connectors on the rear panel.
After you select an Input selection button, the green LED indicator above the
button lights. Selecting an input selects the input image to output to a window. To
deselect an Input button, press that button again.
The MVP 104GX can output all
selected input images to the single
S-video output and the two
composite video outputs
simultaneously.
Freeze control
Pressing the Freeze control button while pressing an Input
selection
button freezes the selected input image window. The
red LED below each Input selection button lights whenever the
input image is frozen. To unfreeze the individual input
windows, repeat this process for each frozen input image
window.
The only way to freeze or unfreeze all input window images in one operation is
through an RS-232/RS-422 command. See the “Programmer’s Guide”
chapter.
Audio input selection
Pressing the Audio input selection button successive times cycles through all
four audio inputs and switches the audio input to audio output. The green
LED for each audio input lights as it is selected.
Selecting past audio input 4 turns off all audio
output and does not light any LED.
Selecting past audio input 4 switches audio to audio input 0 (no audio is
selected). The audio can also be deselected through an RS-232/RS-422
command and using 0 as the audio input number. See the “Programmer’s
Guide” chapter.
