Extron electronic Installation, Connections, VSS 100 Sync Separator Introduction, Extron

Installation

The Extron VSS 100 composite video sync separator extracts the sync signal from an RGsB, component video, S-video, or composite video input. The sync separator outputs the composite sync signal, at TTL levels, on a separate signal line. The VSS 100 loops the input video through and outputs it unchanged.

With the VSS 100, systems that use video formats with embedded sync in the video stream can still take advantage of features that depend on a separate sync input, such as the DSVP™ (Digital Sync Validation Processing™) feature of Extron CrossPoint Plus matrix switchers.

The VSS 100 accepts input video on a female BNC connector. The video input should be the signal that has the sync signal embedded on it, such as the luminance (Y) signal for S-video.

1	Composite video (CV) Input connector — Connect composite
	video (or the video input that has composite sync embedded in it)
	from the video source to this female BNC connector.
	For RGsB video, component video, or S-video, connect the
	following video signal:
	•	RGsB video: Connect the green video signal
	•	Component video: Connect the luminance (Y) video signal
	•	S-video: Connect the luminance (Y) video signal
2	Loop-Thru connector — Connect the included 6” male-to-male

Figure 1 — Typical VSS 100 application

The VSS 100 loops the video input through and outputs it on a separate female BNC connector. The sync separator outputs the separated composite sync, at TTL levels, on a third female BNC connector.

The VSS 100 easily fits behind a rack mounted Extron switcher, and includes a 6” male-to-male BNC cable for easy integration into a video system. The sync separator has an external, worldwide power supply.

Connections

The CV Input and Loop-thru connectors are on the front of the VSS 100. The Composite Sync Out and power connectors are on the back (figure 2).

	cable to this female BNC connector. Connect the other end of the
	cable to the desired destination (such as the green video input of a
	CrossPoint Plus matrix switcher for RGsB video).
3	Composite Sync Out connector — Connect the TTL-level
	composite sync signal output on this female BNC connector to the
	device that needs the sync signal (such as the horizontal sync
	input of a CrossPoint Plus matrix switcher).
4	Power connector — Plug the external 12VDC power supply into

this captive screw connector. Wire the connector as shown at left. Plug the other end of the power supply into a standard AC outlet.
