INTERFACING
PARALLEL INTERFACE
The parallel interface offers two forms of handshaking called
READY and DATA TAKEN. Each 8 bit word appearing on
the data bus is latched with the falling edge of the DATA
STROBE pulse.
This same negative transition notifies the on-board proces-
sor that data has been entered. The READY signal then
goes low and the DATA TAKEN signal goes low momentarily.
The READY signal remains low until the command is
completed or the data has been entered. The DATA TAKEN
pulse indicates when the on-board processor has read the
input latch. Data may be entered into the input latch after
the rising edge of DATA TAKEN.
SERIAL RS-232C INTERFACE
(See J4 pin descriptions.) The controller is considered to be
a DTE type device and will operate with a host that is either
a DTE or DCE device. The serial input and output lines
meet RS-232C specifications. Serial data is entered
asynchronously with selectable baud rates. The byte format
is 1 start bit, 8 data bits and 1 stop bit.

GENERAL DESCRIPTION
The APD-192G088-5 consists of a graphics DC plasma
display panel, IR touch screen, controller and bezel.
The controller maintains all the refresh memory, character
generation, touch panel operation and control logic to enable
the module to serve as a direct I/O device for communica-
tions terminals, computer readouts, microprocessor instru-
ments or any other system requiring a self-contained
terminal. It is programmable to operate in a parallel or RS-
232C compatible serial mode with 7 selectable baud rates
from 300 to 19,200.
Single byte and two byte commands allow simplified code
generation, yet accomplish complex display tasking such as
scrolling or inserting lines and characters. The character
generator is a 4K x 8 bit EPROM with 256 characters
consisting of 128 ASCII characters (including control codes)
and 128 block graphics characters. The character set can
be factory or user modified.
Two means of using graphics are supported - character
graphics, in which the user sends the proper ASCII code to
select the desired graphics character or the bit plot mode.
The character graphics mode allows easy mixing of text and
graphic images and the bit plot mode (using set and reset
commands) allows any graphic pattern to be drawn a bit at a
time.
The infrared touch screen consists of IR LEDs and detectors
arranged to provide a grid of infrared light beams across the
face of the display. If an object is present, then an intersect-
ing pair of beams will be blocked and the controller will
determine the coordinates of that point and report it to the
host computer. Using simple input commands, the touch
screen can be configured to report coordinates when a stylus
is entered into the touch panel, when it is removed or
continuously. Other commands are provided to allow control
over the flow of touch point coordinates between the touch
panel and the host computer.
A DC/DC converter generates the required display voltage
from + 12 VDC and all input lines are LSTTL compatible with
4.7 kilohm pull-up resistors to Vcc.
* Indicates default condition.
NOTE: All touch screen commands are preceded by 18.
