ONE CONTROL BOARD: MANY PRINTERS
This control board accepts input data from a data interface,
such as parallel, serial RS232, etc. and provides the logic and
drive functions needed to operate B-G Instruments' DataPlot
print mechanism model numbers PM1224, PM1320, or
PM1416.The corresponding control board part numbers are:
CB1224, CB1320, or CB1416. Although it is possible to
convert one model control board to another by replacing the
program chip, that procedure should only be performed
by B-G Instrument s or under its
direction. This document pertains to
all 3 control board models.
CHARACTER FONTS
.
DataPlot printer models 1224, 1320,
and 1416 are able to print either
across the width of the paper
(x-direction) or down its length
(y-direction) in 5 different fonts, 4
different sizes of each font and 2
degrees of boldness. Two of these
fonts include both-upper and lower
case, subscripts and superscripts.
Font selections can be made by
software command or through an
attached keypad. Refer to another
data sheet entitled "Standard
DataPlot Character Fonts" for
examples and a complete discussion.
PRINT/PLOT COMMANDS
Printing in the x-direction is done much as on most printers;
send the desired characters followed by a CR ($O D). DataPlot
printers are also able to print in the y-direction and plot high
resolution curves, bar charts, etc., addressing individual dots
and groups of dots as necessary. For a complete description of
these functions and the commands used to invoke them, refer to
another data
sheet entitled "Standard DataPlot Commands".
GENERAL DESCRIPTION
This control board is based on an 80C31 microprocessor with
a complement of other CMOS chips. It provides for both
parallel and serial digital input, a battery-backed
clock/calendar, and interfaces for a keypad and a paper
take-up reel. For analog inputs and other special applications,
a daughter board can be attached with full access to the
microprocessor data bus.
MATING CONNECTORS
The stepper motor (J1) and printhead (J3 or J4) mating
cables are supplied by B-G instruments. Other mating
connectors are:
For J7: T&B Ansley 609-2000M or equivalent.
For J8: T&B Ansley 609-1400M or equivalent
For J9: T&B Ansley 609-2000M or equivalent
For J10: Molex 22-01-3077 housing, 08-50-0114 terminals
For JP1 & JP4, Aries ML100S or equivalent
