Sync Output Menu
As shown in the menu flowchart on page 3-1,
there are four sets of Sync Output menus,
one set for each sync source. The LCD will
display one of four sync output menus:
Green, Composite, Separate H&V (Separate
Horizontal & Vertical), or Auto (Automatic
Sync) - see note below.
The Sync Output menu allows the user to
change the sync output. The sync defaults to
Automatic sync. However, it can be changed
to Composite sync, Separate H & V sync, or
Sync on Green by pressing the or
cursor key. The currently selected sync
setting will not flash, but the alternate settings
will flash. To select an alternate sync setting,
press
NEXT
. After selecting a new sync setting,
allow the time-out to occur to save it.
____ Automatic Sync means the RGB 302/304 detects
which terminated* output connectors are currently
active and will set the output sync as either Sync on
Green, Composite Sync, or Separate H & V, depending
upon the connections. If Separate H & V is detected,
the Vertical and Horizontal polarities are set to
negative (-).
