232-MCT Mono Caption Tuner

232 MCT Mono Caption Tuner

The Contemporary Research 232-MCT is an economical RS-232/IR controlled video tuner featuring mono audio, 125-channel access in CATV, HRC, or IRC modes, closed captioning and intelligent control. Fully programmable, the unit can restore all settings on power-up from non-volatile memory. A list of accessible channels, called channel rings, can be stored in memory, used for convenient channel up/down control and to control direct access to unlisted channels. Switchable inputs for NTSC video and mono audio are included for display of PC graphics, a character generator information channel, camera or other A/V sources.

An onboard character generator displays on-screen text for closed captioning, channel names, and text from a custom control system. Full setup, control, and feedback is provided by RS-232. Up to nine 232-series tuners 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. Enjoy a full range of wireless control with the optional IC-RC IR Wireless Remote.
