Component Key Module Jumpers
The optional Component Key Input module supports one
dedicated component video input and one dedicated key input. Sync is
expected on the Y/G component of the video signal, and on the key
signal. However, if you need to input a video signal that does not have
sync, the module has a separate sync input for this purpose.
There are three jumpers on this module for selecting of Y/G sync or
separate sync, for terminating or unterminating the separate sync signal,
and for selecting the level of sync on the key signal. The following table
describes the functions and settings for each jumper.
Jumper Function Pin Connections
JP1 Selects level of
the sync on key
input 1-2 = 300mV sync (default)
2-3 = 2V/4V sync
JP2 Selects sync on
video or separate
sync 1-2 = video sync (default)
2-3 = separate sync
JP3 Terminates or
unterminates the
separate sync
input 1-2 = 75-ohm term (default)
2-3 = hi-z termination
