The APD-256M025A-1 plasma display module consists of a multiplexed DC plasma display, driver circuitry and a
microprocessor-based controller board. Vishay Dale's
®
patented open construction display technology assures a stable,
flicker free screen.
The parallel interface is a basic 8 bit parallel ASCII interface with handshaking and some dedicated control lines. The ASCII
data and command data are presented to the unit in positive logic convention. Data is entered by first placing the data to be
strobed into the display on the data bus. A negative going strobe of 200 nS on the WRITE pin will notify the controller that data
is available. The controller will respond with a positive going BUSY signal that will remain a logic one until the controller is
ready. The system microprocessor handles input data rates up to 10 kHz. Data format for serial interface is 1 start bit, 8 data
bits and 1 stop bit. Baud rates from 150 to 19,200 can be selected. The serial interface can be programmed for RS-232 or TTL
voltage levels. The display can operate with no handshaking at the highest baud rate, as it has a 20 character buffer to capture
data while doing long commands. However, it is important to note instruction execution times to prevent loss of data in the
event that several long commands are placed in sequence. The EPROM based character generator is programmed with an
international character set which includes the standard ASCII characters. It can be factory or user programmed for other
character sets. The logic input is one HCT type input with a 4.75 kilohm to + 5 VDC. The output is driven from a 74LS06 open
collector gate and is not internally pulled up.
