Real Time Clock Option

Product Announcement

The Burst Electronics Model MCG-3 (and RCG-3 version) Color Video Character Generator is no longer in production. The heart of this product, a special chip (IC) is no longer being produced by the IC manufacturer. The manufacturer of this very key part did not notify us that they were going to discontinue production. We no longer have units in stock, but we continue to provide service and repair for the MCG-3 and RCG-3.

Maximum number of characters displayable per page is 240 (24 characters by 10 lines) with 10 pages of nonvolatile storage. There are 16 character sizes (4 character heights and 4 character widths) allowing page by page text emphasis control. Individual characters may be set to blink for an additional effect. Built-in Menus, Help Screens and Self-test all add to ease of use.

Text input is performed with front panel push buttons in a "letter up/letter down" and "cursor left/cursor right" fashion. An RS232 interface for connection to a PC is standard, allowing full control of the MCG-3 including downloading text.

In the overlay mode (input video present), the MCG-3 may be set to automatically switch to the stand-alone mode and display a special message (page 10 of its memory) upon loss of input video. Additionally, the MCG-3 incorporates a video bypass circuit that will loopthru video upon loss of power to the MCG-3.

A Real Time Clock Option is available that allows Time of Day and Date information to be displayed. The RTC can be programmed by the front panel or via the RS232 link for additional flexibility.

Applications include Source ID, Bulletin Board Displays, Subtitling, Message Screens, Time Keeping and Clock Display Applications.
