Feature Packed Six built in fonts in SOH/ETX mode with 7 justification modes, normal or inverted, on/off/XOR. Simple to use graphics commands for displaying bitmaps, drawing lines, boxes, and circles.
You can use your choice of matrix or non-matrix keypads, allowing 8 to 16 key inputs, and or plug in a PS2 keyboard.
An on board tone generator & amplifier can be used to provide user feedback.
Built in, expandable EEPROM's allow storing of graphics pages for quick menu redraws and graphics animation.
SOH ETX Protocol uses simple ASCII commands to: display text in five different
fonts, clear all or portions of the display, draw lines, boxes, circles, display
bitmap files, generate tones, and more. An optional display address
can be set, using the built in non-volatile configuration utility, to allow multiple
displays to be on the same serial port, each displaying different
information.
ANSI / VT100 Subset
Protocol supports ESC control sequences: display text in fixed pitch 40 column
by 30 row font, clear all or portions of the display, cursor positioning,
scrolling when last line of display is reached, line wrap support, CR - CR/LF
support, generate tone, ESC function key support for keypad closures, and more.
Graphic Overlay Available!
Splashproof Case Available!
Cost Effective The 320 x 240 Serial Graphic LCD Terminal provides you with a cost effective 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 many off the shelf enclosures. 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 320 x240 Graphic LCD Terminal for an interface to the automation control system. Most automation platforms allows formating 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 320 x 240 Graphic LCD Terminal in a remote location.
Easy to use In's and Out's Simple ASCII serial commands sent to the 320 x 240 graphic LCD display terminal display text in multiple fonts/styles/justification, graphics, and generate tones via the onboard 250mW speaker driver. ASCII serial commands are sent from the 320 x 240 graphic LCD display terminal for switch closures and openings when switches are debounced. When the touchscreen is pressed, you can have the X and Y location sent, or have the on-screen keyboard displayed and touched keys are sent out the serial port. You can have a great looking user interface in no time at all.
Configuration is easy. By simply holding down two keys or touching a location on the screen 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 saved in non-volatile EEPROM.
An optional 5.3" x 4" white Graphic Overlay with clear window and 3M adhesive is
available for easy mounting. • Splashproof IP-64 rated, with a Low profile height of .059 inches.
The serial 320 x 240 Graphic LCD Terminal with touchscreen to the
right, is shown mounted in a PC-TEC OD56 splashproof IP-67 outdoor rated enclosure. The graphic overlay with 3M adhesive is rated IP-64.
This machined enclosure may be order on our online store. This method of mounting, provides you with a low cost professional user interface solution.

| Keypad |
For inputs, theres two choices: 1) A eight 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 four column by four row matrix keyboard input. This setup allows for a matrix of 16 keys to be used, and can
also use the bottom line of the display to act as soft menus. |
| Audio |
For audio, there's a four 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/RS-485 connector. 10 - 15VDC
is required. Current draw is 32mA when LED backlight is off, 190mA when on. |

Firmware Downloads
For PCB Rev 8:
Download version 1.0 firmware for the 320 x 240 Rev 8 PCB[AcsLcd320x240FirmwareV1_0.zip]
Initial Release
Download version 1.1 firmware for the 320 x 240 Rev 8 PCB[AcsLcd320x240FirmwareV1_1.zip]
Corrected ANSI mode in comm.c so it works without either NV_AnsiAddLfToCr or NV_AnsiAddCrToLf being enabled.
Download version 1.2 firmware for the 320 x 240 Rev 8 PCB[AcsLcd320x240FirmwareV1_2.zip]
Removed CLEAR_UART1_RX_INTERRUPT() in UART1_ReceiveInterrupt() that could cause intermittent loss of received PS/2 characters.
