VSCC Installation Manual
S-Video Closed Caption Decoder
CRSystem Tools
The VSCC S-Video Closed-Caption decoder gives integrators a simple, reliable way to decode and display closed caption
text in both S-Video and composite video formats. Employing technology developed for the 232-STS S-Video TV Tuner, the
VSCC provides digital 2-D adaptive Y/C separation for superior S-Video signals from a composite NTSC video input.
Front-panel settings can select eight Closed Caption modes and remote control operation. A captive-screw control port
accepts a closure for Captions On/Off, sends a logic-level output for sensing video presence, and allows remote DC power.
Designed for versatile installation, the compact VSCC can be operated on a tabletop, attached to a display, or rack-
mounted 3-across, mixed with other CR System Tools using the optional single-rack height RK3 Rack Kit.

VSCC Installation
Video and Power Connections
Video In: Connect BNC composite NTSC video
S-Video Out: Connect S-Video cable (2-D Y/C processed video plus captions)
Video Out: Connect BNC composite NTSC video (input video plus captions)
DC Pwr: Connect DC power supply, Green Pwr LED lights when DC power is active
Operation: Video output should include captions, CC1 mode (default setting)
Caption/Control Settings
Caption/Control: 4-position DIP switch sets caption and control operation
Default setting is all switches off (up): CC1 caption type, Latching caption on/off control
1. Set Control Options by setting Switch 4 On, then Switch 1 On or Off.
2. Set Switch 4 to Off (Caption Mode)
3. Set Caption Options using switches 1 -3 for caption type CC1 - CC4 or TT1 - TT4
4. If you change Control Options, reset DIP switches to desired Caption Type
Control Port
Control Port: Wire captive-screw terminal as shown above
Pin 1: GND
Pin 2: Captions On/Off Input, latching or toggling, closure to GND, max 50 mA
Latching mode: Closure turns captions off, release to turn captioning on
Toggling mode: Momentary contact toggles between captions on and off
Pin 3: Captions Output, On = logic level low, max 50 mA, Off = Logic high, 5V through 10K pull-up resistor
Pin 4: Video Detect Output, On = logic level low, max 50 mA, Off = Logic high, 5V through 10K pull-up resistor
Pin 5: 12 VDC input, electrically identical to Pwr In
11.5 to 16.5 VDC, 12 VDC typical (may be unregulated)
