Extron electronic SVS 100 manual Genlock and Vertical Interval Switching, Genlock connections

Connect the sleeve to ground (Gnd). Connecting the sleeve to a negative (-) terminal will damage the audio output circuits.

By default, the audio output follows the video switch. Audio breakaway, commanded via the Windows-based control program or under RS-232/RS-422 control, allows the user to select from any one of the four audio input sources. See to chapter 5, Serial Communication, for details.

Genlock connections

A genlock device (black burst generator) can be connected to the SVS 100 via the BNC connectors shown below. The genlock feature allows the SVS 100 to be synchronized with other system components for seamless vertical interval switching between sources. See Genlock and Vertical Interval Switching in this chapter.

Figure 2-6 — Control device and external sync connections

10Genlock In connector — Connect an external black burst signal to this BNC connection for genlocking the video signal in broadcast or other sync-critical applications.

11Genlock Out connector — Connect any downstream equipment that requires genlocking to this BNC connector to route the black burst signal throughout the system in broadcast or other sync-critical applications.

RS-232/RS-422 connection

12RS-232/RS-422 port — Connect a host device, such as a computer or touch panel control, to the SVS 100 via this 9-pin D connector for serial RS-232/RS-422 control. See chapter 5, Serial Communication, for details on how to install and use the control software and the SIS commands.

The SVS 100 comes from the factory already configured for RS-232. To set the

SVS 100 for RS-422 operation, please see “Configuring the SVS 100 for

RS-422” in the Appendix.

Genlock and Vertical Interval Switching

For vertical interval switching (to allow clean switching between signals from several devices during the vertical blanking period of each signal), a composite sync signal can be applied at the Genlock In connector, and also passed to another device via the Genlock Out connector.
