Interface Switches

Switch Setting	Function
Standard Select	In the Man position the user can force the
	output standard to the required mode (in
	case of an input signal mismatch the
	module gives the Error LED indication). If
	the user always operates in only one
	standard it is advisable to use the Man
	mode for faster lockup. In Auto mode the
	VSM-6804 determines and switches to the
	detected line standard.
Force	This is to select between 525 and 625 line
	standard modes and active only if Standard
	Select is in Man position.
525 Standard	This is to select between output standards
	NTSC and PALM. Since the incoming
	signal is component digital this selection is
	always made by the user even in the Auto
	mode.
Vertical Blanking	In the Pass mode the encoder is
	transparent in the vertical blanking. In the
	Blnk mode any luminance and
	chrominance data is substituted by black.
	(no setup in case of 525 signals.)
Vblank Chroma	In the Off position the chrominance
	content is removed from the signal in the
	vertical banking area, otherwise
	transparent.
