2 MCG-2 Micro Character Generator
PART ONE
Introduction:
The MCG-2 is a low cost B/W character generator for adding titles or
captioning to NTSC or PAL Color or Monochrome video. The MCG-2
will automatically Genlock to either NTSC or PAL inputs with no
adjustments or switch settings required. The MCG-2 outputs black or
white characters (user adjustable), appropriate for logging and
documenting experiments, video source I.D., camera and location
display for security applications, time and date stamp from a PC (or the
MCG-2 with the real time clock option), Patient monitoring,
Information displays, and basic CG applications. The MCG-2 requires
a video input to operate.
The unit displays a maximum of 180 characters (9 lines by 20 letters).
Characters may be set to 4 widths and 4 heights for a total of 16
character sizes.
The character set includes upper case letters A–Z, numerals 0–9, and
various punctuation marks and symbols as shown in the ASCII to
MCG-2 Display Convert table. Characters may be set to have
background or to flash or both. Characters and background brightness
may be individually set with "screwdriver" adjusters on the rear panel.
The display memory holds 10 pages of text and is protected from
power losses by a lithium cell that should last 10 years (3 years if RTC
is installed). Stored on a page by page basis for each page is: the
character size, display position, background on/off status, and the
position of the Real Time Clock Display.
The MCG-2 may be controlled by either front panel controls or
remotely by an RS232 link to a PC.
Multiple units may be chained together with standard 4-conductor
RJ11 modular telephone cable and individually accessed from a PC.
Easy to use two letter commands are sent to the MCG-2 from a PC
