The 128 x 64 Serial Graphic LCD Terminal provides you with a low cost user interface solution for that great product/project you have developed. The LED backlighted display is a high contrast transflective LCD, which allows great indoor and outdoor viewing both night and day. The printed circuit board is shaped to fit into any type of an enclosure, a double width electrical box, or an off the shelf PAC-TEC "TT" hand-held enclosure. This allows you to make your own custom terminal, operator interface, and or machine interface. Long 2-56 flat head screws and standoffs are included for mounting.
Home, business, and industrial automation designers & developers can use the serial 128x64 Graphic LCD Terminal for an interface to the automation control system. Most automation platforms allows formatting and sending serial data as well as receiving. Using this built in communications capability, you can add an operator interface. Also, since it's serial, you can add the serial 128 x 64 Graphic LCD Terminal in a remote location.
Best of all, it is easy to use! You can have a great looking user interface in no time at all. Simple ASCII serial commands sent to the 128 x 64 Graphic LCD Display Terminal, display text in multiple fonts/styles/justification, graphics, and generate tones via the onboard 250mW speaker driver. ASCII serial commands from the 128 x 64 Graphic LCD Display Terminal debounce switch closures from either a scanned row & column keypad, or individual contacts.
Configuration is easy. By simply holding down the outer two bottom keys at power up or reset, the display terminal enters a configuration utility menu. From this menu, you can change the baud rate, display address, back light timeout, power up logo & settings display, and more. After changes are made, they are save in non-volatile EEPROM.
An optional 3M adhesive backed membrane switch overlay is
easy mounting. • Seven Keys • Tactile feedback
on all keys • Attached .1” female connector • Rim embossed keys for finger placement
• Splashproof, sealed switches • 4" in width, by 3" in
height, with a Low profile height of .059 inches.
The serial 128 x 64 Graphic LCD Terminal to the
right, is shown mounted on a dual gang outlet box cover. This method of mounting, provides you with a low cost professional user interface solution. A mechanical drawing is in the manual for mounting the display terminal in this fashion.
|CPU||Zilog Z8F6423, 64K of FLASH, 4K of RAM|
|LCD||128 horizontal pixels by 64 vertical pixels, with a 1/64th duty cycle. A contrast adjusting knob is provided for adjusting the displays viewing characteristics. Viewable Area: 2.82" x 1.53". Dot Size: 0.019" x 0.019". Dot Pitch: 0.020" x 0.020"|

19,200, 38,400, 57600 N,8,1
Baud rate defaults to 9,600, and can be changed by holding down two inputs on power up or reset, and entering the configuration menu.
For inputs, there are two choices:
1) An seven button debounce(non-matrix) keyboard input. Using four of the inputs, this setup allows for the bottom line of the display to act as soft menus.
2) A three column by four row matrix
keyboard input. This setup allows for a matrix of 12 keys to be used, and can
also use the bottom line of the display to act as soft menus.
For audio, there's a two pin connector for connecting a 8-32 ohm speaker for tone generation. A 250mW audio amplifier is provided.
|Power|| Power for the
terminal comes in on two of the unused DB-9 RS-232 connector. 10 - 15VDC
Current draw is 32mA when LED backlight is off, 190mA when on.
