Plasma Panel Display Modules
480 Character Display with Drive Electronics, Controller and Parallel Interface
FEATURES
* 480 (12 x 40) alphanumeric characters (5 x 7 dot matrix) * Only + 5 and + 12 VDC required (- 2 option) * ASCII character set (optional character sets available) * Efficient Parallel Interface * Two Step Brightness Control * Wide viewing angle (150) * Rugged design/slim profile * Flicker free refresh * Editing functions * Panasonic/NEC/Babcock Compatible The APD-480M021 display module displays up to 480 alphanumeric 5 x 7 dot matrix characters arranged in 12 lines of 40 characters each. The module includes drive electronics, a controller consisting of refresh memory, character generator and control logic with ASCII input to enable the module to serve as a direct readout device for many applications including POS terminals, industrial controls, computer peripherals, measurement instruments, and office machines. (A serial interface version is available APD-480M021-1.)

Vishay Dale
GENERAL DESCRIPTION
The APD-480M021 consists of a DC plasma panel display, drive circuitry, and controller. The interface is a basic 8 bit parallel ASCII interface with handshaking and some dedicated control lines. Vishay Dale's(R) patented open construction display technology assures a stable, flicker free screen. The controller maintains all the refresh memory, character generation and control logic. It supports back space, horizontal tab, line feed, vertical tab, clear, carriage return and escape through software instructions. Control commands available include reading cursor position and data, horizontal tab after reading data at cursor position, character insert, character delete, line insert, line delete and screen clear. Operating modes are "normal" (wrap-around) or vertical scroll. The cursor may be turned on, or off, or on with a 4 Hz blink rate. The EPROM based character generator is programmed with an ASCII character set, but is easily configured for any character set. The logic input is one 74LS type input with 4.75 kilohm to + 5 VDC. All input lines also have a 1000 F capacitor to ground.

INTERFACE SIGNAL DESCRIPTION
DB0-DB7 (Data Bus) - Tri-state bi-directional data bus to exchange data between display and host processor. CHK (Check Command) - If CHK is low, any character written will fill all positions on the screen. After CHK is low, momentarily pulling CLR low will start a self-test where all the characters in the character set are scrolled from right to left. WR (Write) - Enter data while WR is low. RD (Read) - Read data while RD is low. A0 (Address Bus) - Selects character control codes or control command. A0 = low enables writing data. US (Unit Select) - Read and Write commands will only influence display while US is low B/D (Brightness/Dim) - Brightness is reduced 50% when B/ D is low. BL (Blank Screen) - Screen blanked when BL is low, but the data and cursor are maintained. CLR (Clear Display) - Display memory is cleared and the cursor goes to the HOME position when CLR is low. BUSY (Busy Signal) - I/O is inhibited while BUSY is high. This output is driven from a 74LS06 open collector output and is not pulled up.
