ELECTROMAGNETIC INFORMATION DISPLAYS |
|
Display of text and graphic information by means of electromagnetic dots - designed for interior and exterior
|
|
|
| display by means of principle of passive reflection - a reflective side of the display writers reflects back the light. The displayed information is better visible with better illumination.These panels are appropriate for high-level of ambient illumination or with internal lighting.It is possible to use an internal or external lighting or lighting of LED connected to display writers if the ambient illumination level is low. |
| information is displayed by means of reversing of coloured reflective side and black dull side of display writer |
| low power drain |
| information is saved after a voltage disconnection and it is possible to display last displayed information |
| display colour - yellow, red, green, white or orange |
| generating of audio signals |

| TEXT AND GRAPHIC DISPLAYS - DISPLAYS COMPOUND OF A DOT MATRIX |
It is possible to display text and graphic information simultaneously.
|
| other products made to order |
| possibility to inverse the display of the text |
| a time schedule of the display |
| Examples |
 |
 |
|
|
| display writers are single electromagnetic dots - yellow, red, green, white or orange |
| it is possible to connect yellow LED to each display writer for a better visibility |
| display writers life expectancy - 100 millions operations |
| the display surface is usable in text or simplified graphic mode |
| minimal raster of a character - 5 x 7 dots |
| displays consist of modules with raster 14 x 19 dots. Modules are assembled to required proportions. |
|
It is possible to assemble modules: |
| dot diameter 10 mm |
horizontally to a sheet |
| |
vertically with spaces |
| dot diameter 15 mm |
horizontally and vertically to a sheet |
Recommended minimal raster 56 x 19 dots.

wireless by means of GSM module
data network by TCP/IP protocol
|
|
OPERATING SOFTWARE |
|
SW is a part of a supply: |
| it enables a direct operating of the panel |
| it enables editing of displayed information |
| selection of a type font, height of characters and text placing |
| a time schedule of display |
| information is saved after a voltage disconnection and it is possible to display the last displayed information |
|
|
Customer's SW:
|
|
the APEL® company provides a communication protocol
|
| OPERATING MODE |
|
on-line :
|
the display is operated by a supervisory system |
| off-line : |
it is possible to disconnect the operating PC after the transmission of the information to the display. The display shows text in sequences with set effects by means of a built-in microcomputer.
|
| POWER SUPPLY |
230 V AC
low power drain
|
| DESIGN |
|
the display is standard in an aluminium case of natural colour or in a case with a frame
the case for interiors or for exteriors
a field for the fixed text may be a part of the panel
the front side of the panel is equipped with Perspex
|
| INSTALLATION |
| according to customer's request - ex. hanging on the wall or on the ceiling, fixing into the wall, a stand, a portable case
