MULTITEXT ALLOWS TO VISUALIZE TEXT PAGES ON MULTIPLE LINES. THIS MODEL IS NECESSARY WHEN THERE IS THE NEED TO DRAW ATTENTION ON IMPORTANT INFORMATION AND TO MAKE WRITING READABLE ALSO FROM HIGH DISTANCE (FROM 5 TO 80 METERS ACCORDING TO THE MODEL).

Message programming can be done through a personal computer and our software Mediatext-Pro (compatible with Windows98/XP). The text inserted on the PC is transmitted to the display with RS232/422/485 or Ethernet connection. If you don't want a cable it's also available the Wireless interface. To resolve spefic problems and situations we can develop custom software (example: subtitlings of films in cinemas). In addition, to enable users to develop their own specific software, the serial communication protocol is provided. In the industry you can use the board Multitext connecting to a PLC. The PLC can send the text through our communication protocol Mediapro-link via either a serial or Ethernet, or, contacts cleaned by N N / A, can give the input for displaying N messages pre-stored. Multitext remembers the message, even when turned off as long as there remain in this condition for more than 90 days. It can display time and date. Models are available with a single color (monocolor) with choice between red (standard), green, yellow, amber and blue (optional) and tricolor models that can simultaneously display three colors: red, green and yellow.

To choose the most suitable model Multitext ask yourself three main questions: 1) must be installed in an indoor environment or outdoors with direct sun light? - 2) from which distance should be readable? - 3) how much information must be readable displayed on each page? So how many lines and characters per line must be composed of the display?

The Multitext are divided into six main types characterized by the height of the characters and their brightness.
The following character heights are available:

  • Cm. 3, readable up to 9-12 meters;
  • Cm. 5, " 15-20 meters;
  • Cm. 8, " 24-32 meters;
  • Cm. 11, " 33-44 meters;
  • Cm. 16, " 48-64 meters;
  • Cm. 20, " 60-80 meters;

On 3 and 5 cm models are mounted LED (Light Emission Diode: the bright side of the device) of "Dot Matrix" type: they have a not excessive brightness and readable from any angle, this type of LED is recommended when the display must be installed in an indoor environment is not directly illuminated by sunlight. On all other models are mounted LED Superbright type with 2600 MCD: they are easy to read even in the presence of strong sunlight and are therefore suitable for outdoor installations. The displays with LED Superbright Multitext are also recommended for the inside if there is a strong artificial light, as in the case of a television studio, or when they must be readable by over 12 meters. It can have the following quantities of characters per line: 10, 13, 16, 20, 26, 30, 40 and 60. .

You can request a detailed list of all available models with the features and prices by selecting Request information and quotes . The case of the display box Multitext is designed to be installed outdoors exposed to weather conditions (IP54). It is also possible to request a greater degree of protection for cases in which the display is to be installed in an environment more critical, for example in places where they are used strong jets of water also from bottom to top (IP65) or in a shed industry where there are very aggressive acid vapors.

What is it for?

Multitext is an information tool.
It is very effective where there is a need to attract the attention and deliver real-time information that is readable from a distance (up to 80 mt.). Compared to traditional monitor also it has the advantage of being much brighter and therefore also clearly visible in rooms lit by direct sunlight.

What it can visualize?

Some examples of messages that can be viewed for different uses:


  • Industries: per messaggi di servizio, informazioni sulle commesse, dati di produzione, raccomandazioni sulla sicurezza, dati sugli infortuni accaduti, descrizione lavorazioni, dislocazione dei materiali, etc;
  • Airports and Train Stations: for arrivals and departures and messages to passengers;
  • Hospitals: to inform people about the services provided and the dislocation of the various units within the building;
  • Streets: for information about on road conditions and safety;
  • Parkings: for availability of places and service information;
  • Exhibition stands: to advertise products and services offered;
  • Waiting rooms and entrances to public: for general information.
How it connects

Multitext can be interfaced with a PC or PLC or a network with the following connection types:

  • RS232
  • RS422
  • RS485
  • Ethernet
  • Wi-Fi
  • Radiomodem
  • GSM via SMS sending
  • GPRS via Internet
  • Parallel 8-bit binary input for the selection of pre-stored pages

Available typologies

The standard production of Multitext displays is made up of 70 models that differ in the number of lines and the height of the characters.

Number of text lines

The standard models have a number of rows from one to eight. Each line is made up of 20 characters.
Up to 64 rows and 60 characters per line can be provided on request.

Characters height

  • Cm. 5, " 15 meters;
  • Cm. 8, " 24 meters;
  • Cm. 11, " 33 meters;
  • Cm. 16, " 48 meters;
  • Cm. 20, " 60 meters.
How to choose the right typology

To choose the display that suits your needs, you should ask the following questions:

  • Since I can see the text alternating the display of multiple pages, how many lines and how many characters per line do I need?
  • From what distance should the message be readable?
  • How do you want to control the display? ( see "How it connects" );
  • Is the LEDs color red good for you or do you want a different color? (Green, yellow, blue);
  • Must it be installed indoors or outdoors exposed to weather?
  • Are there particulates in the environment or aggressive acidic vapors?
  • What power supply do I have at the installation site? (12V, 24V, 110V, 220V).

If you send us a request with the above information we can form you a quick quotation.

Calculate the reading distance

The reading distance depends on the size of the characters that the display is capable of displaying. The reading distance does not depend on brightness. The following table shows the read range depending on size. By convention we refer only to character height.
