Overview 3. Overview The VS-812 is a unique dual-format switcher and distribution amplifier for composite and s-Video (Y/C) and balanced stereo audio signals. Each of the eight inputs can be configured as either composite or s-Video (Y/C) and is converted to produce composite and s-Video (Y/C) outputs simultaneously.

Connecting the VS-812 8x1 Composite / s-Video / Audio Switcher 6.3.1 Preparing the RS-232 Connectors To connect a PC to a set of VS-812 units, do not use a Null-modem adapter. Do the following: 1. Prepare the RS-232 9-pin D-sub connector (A), by connecting PIN 4 to PIN 6 and connecting PINS 8, 7, and 1 together. 2. Attach the RS-232 9-pin D-sub connector (A) to another RS-232 9-pin D-sub M connector (B) by connecting PIN 5 to PIN 5, PIN 3 to PIN 2, and PIN 2 to PIN 3. 3.
Connecting the VS-812 8x1 Composite / s-Video / Audio Switcher 6.3.2 Shorting Jumpers JMP4 and JMP5 When connecting a PC to a set of VS-812 units you need to adjust the factory default by opening each VS-812 unit, shorting (closing) Jumpers JMP4 and JMP5, and then closing each VS-812 unit. Figure 11 illustrates the location of Jumpers JMP4 and JMP5: Jumpers, JMP 4/5 Figure 11: Location of Jumpers JMP4 and JMP5 6.3.

Operating Your Composite / s-Video / Audio Switcher 7. Operating Your Composite / s-Video / Audio Switcher You can operate your VS-812 via: • The INPUT SELECTOR buttons (1 to 8) and the INPUT SETUP switches (1 to 8) on the front panel • RS-232 serial commands transmitted by a touch screen system, PC, or other serial controller 7.1 Using the Front Panel Buttons and Switches You can only select one 1 video source at a time.
Operating Your Composite / s-Video / Audio Switcher 7.1.2 Selecting a CV or a Y/C Source on an Independent Unit After connecting a composite video source to CV IN # 1 and an s-Video (Y/C) source to Y/C video IN # 1, set the INPUT SETUP switch # 1, as appropriate, before or after pressing the INPUT SELECTOR button # 1.
Operating Your Composite / s-Video / Audio Switcher 7.1.3 Selecting a CV or a Y/C Source on a Set of three VS-812 Units When operating, for example, a set of three looped VS-812 units, not all the INPUT SELECTOR buttons on the front panels of the combined VS-812 units are active. For example, as Figure 15 illustrates, with a combination of three switchers, you cannot use all the eight INPUT SELECTOR buttons on each looped VS-812 unit.
Operating Your Composite / s-Video / Audio Switcher 7.2 Switching and Distributing Your VS-812 is both a switcher and a DA.
Operating Your Composite / s-Video / Audio Switcher 3. Press the INPUT SELECTOR button # 3 1. INPUT SELECTOR button # 3 illuminates, indicating simultaneous distribution of the: Composite video and audio source # 3 to CV Video Acceptor 1 at the composite video OUT 1 connector and to CV Video Acceptor 2 at the composite video OUT 2 connector Converted composite video and audio source # 3 to s-Video Acceptor 1 at the Y/C video OUT 1 connector and to s-Video Acceptor 2 at the Y/C video OUT 2 connector 4.
