Contemporary Research 3 232-STS Stereo S-Video TV Tuner

The Contemporary Research 232-STS is a versatile RS-232 controlled TV tuner featuring high-quality

S-Video video and balanced stereo audio output, switchable composite AV input, closed-captioning and on-screen

text, 125-channel access in off-air, CATV, HRC, or IRC modes, front-panel operation and feedback, and intelligent RS-

232 control. Fully programmable, the unit can restore all settings on power-up from non-volatile memory. A list of

channels can be stored in memory, used to provide convenient channel up/down operation and restrict direct access

to other channels. Enjoy a full range of wireless control with the optional IC-RC IR Wireless Remote.

An onboard character generator displays on-screen text for closed captioning, channel names, interactive menus, and

system feedback. Switchable inputs for composite NTSC video and stereo audio are included for display of PC

graphics, VCR, camera or other A/V sources. AV from inputs and off-air broadcast are output as composite video, S-

Video and balanced/unbalanced stereo audio.

The front-panel buttons, LEDs, and channel/mode display can be used for general operation and to program basic

features for tuning, RS-232 baud rate and local control. Full setup, control, and feedback is provided by RS-232. Up to

nine units can be controlled from a single RS-232 port. In addition, remote tuning ring channel up and down operation

can be accessed through contact closure inputs.
