GENERAL DESCRIPTION
The APD-064M033 plasma display module consists of a
multiplexed DC plasma display, driver circuitry and a
microprocessor-based controller board. The interface is a
basic 8 bit parallel ASCII interface with handshaking and
some dedicated control lines or a serial data interface which
requires no handshaking. The EPROM based character
generator is programmed with an ASCII character set but is
easily configured for any character set. Vishay Dale’s
patented open construction display technology assures a
stable, flicker free screen.
Parallel ASCII and cursor data are presented to the unit in
negative logic convention and a separate strobe line for
each determines which is entered. A single busy signal
indicates to the host system when the display is busy. The
logic input is one 74LS type input with a 4.75 kilohm to + 5
VDC and a 1000pF capacitor to ground. The output is
driven from a 74LS06 open collector gate and is not inter-
nally pulled up.
The serial interface is RS-232 compatible. Baud rate is
9600(other baud rates can be supplied) and the data byte
format is 8 data bits, 1 stop bit and no parity. The serial
interface supports Reset, Backspace, Line Feed and
Carriage Return in addition to Cursor Position selection.

The APD-064M033 display module displays up to
64 alphanumeric 5 x 7 dot matrix characters arranged in
4 lines of 16 characters each. The module includes drive
electronics, a controller consisting of refresh memory,
character generator and control logic with ASCII input.
Interfacing is very simple and requires minimum handshake
to enable the module to serve as a cost effective direct
readout device for many applications including POS termi-
nals, industrial controls, computer peripherals, measurement
instruments and office machines. Serial and parallel
versions are available as well as single + 5 VDC power
input.

INTERFACE SIGNAL DESCRIPTION
DB0-DB7 (Data bus) - Data bus to enter character and
cursor data.
CUR-LD (Cursor Load) - The cursor is moved to the
address given by DB0-DB7 where:
00H = home position.
0FH = last character position, 1st line.
3FH = last character position, 4th line.
WR (Write) - The ASCII character, as defined by the code
given by DB0-DB7, is displayed at the selected address.
The display auto-increments from a given address.
BUSY (Busy Signal) - I/O is inhibited when busy is high.
