KD-VA5 Operating Instructions

Configuration and Operation (continued)

Video Formats

The KD-VA5 supports only the following, most popular analog interlaced and progressive video formats, like HDTV, NTSC, and PAL:

›1080i (60 & 50 Hz)

›720p (60 & 50 Hz)

›480p (60 Hz)

›576p (50 Hz)

› 576i (50 Hz, SCART only)

Auto Sensing

The KD-VA5 senses the appropriate Mode of operation, using Intelligent Auto Sensing™:

Component-to-RGBHV	If the Component Video input is connected with active
Mode	sync on Y, the Intelligent Auto Sensing™ automatically forces
	the KD-VA5 to the Component-to-RGBHV Video Mode by
	sensing active sync on the “Y” Component Video signal.

RGBHV-to-Component	If there is no YPbPr input (in particular, no sync on the “Y”
Mode	channel), the unit automatically selects the RGBHV-to-
	Component Video Mode.

See the Application Examples earlier in this Operating Manual. In each mode (RGBHV-to- Component Video or Component-to-RGBHV Video) the corresponding Red LED should be lit. Active sync on the “Y” Component Video input forces the KD-VA5 to operate in the Component- to-RGBHV Video mode. To override this mode, you must turn off the Component Video source. However, you may also need to disconnect the “Y” cable in some cases, in the event the Component Video source continues to provide sync on the Y channel even when power is not supplied to the Component Video source (this may happen in some instances with e.g. a Set Top Box).

Slide Switch Sync Settings

Locate the block with the three (3) small Slide Switches labeled “1” “2” “3” on the side of the unit, near the Pb Y Pr Input connector. The “Up” position is the “default” position (most typical applications use these settings) that corresponds to the Green LEDs being lit on the face of the unit. The “Down” position selects the corresponding Yellow LEDs active.

“Up” for Green (default)

“Down” for Yellow

	Switch in the DOWN position	“Default”: Switch in the UP position
	Yellow LED ON	Green LED ON

Switch 3	SCART Input: RGB Video and	RGBHV Video Input on the HD-15 VGA
	Composite Sync on H	Input connector

Switch 2	RGB Video Out: Sync is on the	RGBHV Video Output, with separate
	Green channel (RGsB)	H & V sync

Switch 1	RGB Video Out: Composite Sync	RGBHV Video Output, with separate
	provided on the “H” Output	H & V sync (the “H” channel carries H sync
		and not Composite Sync)
