Standard modulesEA P204-BHNLED dot-matrix display
The dotmatrix LCDs offered here are all equipped with the controller HD44780 or compatible; they contain a complete character set and are configured for operation on the 4- or 8-bit data bus of a processor system. There are R/W, RS and Enable control lines. Please ask about special models with an extended temperature range, a Cyrillic character set or a soldered connector. Semi-customized solutions are possible as of 50 units. The accessories we supply for dotmatrix LCDs include suitable bezels, RS-232 interfaces and EL inverters for displays illuminated by means of EL foils.
Prices if you order in hundreds are between EUR 5.75 and EUR 192.76*) per unit (plus shipping costs). We have a large stock and can thus deliver many models immediately from our stock in Graefelfing near Munich.

 The series with RS-232 / RS-422 EA SER series EA SER402-NLED with cabel
Fixed-text displays for 64 messages EA TXT series

The series we are talking about here is an LCD dotmatrix series complete with a control interface and bezel. The LCD module, which includes an RS-232 interface, is delivered as a unit. It is connected to a standard RS-232C interface (or, alternatively, an RS-422).
You will find more information on this on the rs232 page.

 Dynamic dotmatrix displays EA DYN204-NLED

Dynamic dotmatrix modules permit 4 different font sizes to be displayed simultaneously. As a result, text or measurement values can be highlighted and are thus also visible from some distance. They are controlled via their integrated RS-232 interface.
You will find more information on this on the rs232 page.

 RS-232 / RS-422 controllers EA 9706-V24

The EA 9707-V24S interface allows dotmatrix LCDs to be programmed easily and quickly. The interface can be soldered directly onto almost all dotmatrix modules. It is connected to a standard RS-232C interface.
The data transmission rate can be set to 300, 1200, 2400 or 9600 bps. Umlauts (ä, ö, ü, ß, Ä, Ö, Ü) are interpreted as extended IBM code and recoded. If the display is full, it scrolls upward automatically. CR ($0D,13d) and LF ($0A,10d) are identified and executed. This automatic function can be switched off for individual cursor positioning. The supply voltage is +5V/typ. 1mA or +9..35V optionally. The interface can also be supplied with an RS-422 interface (EA 9707-V24S OPT-RS422) instead of RS-232.
The EA 9707-V24S can be connected directly to the 9-pin subminiature D connector of a PC, for example, via the EA KV24-9B cable (approx. 1.50m).

The price for the standard RS-232 EA 9707-V24S controller if you take a batch of 25 is EUR 44.37*). Smaller quantities of the interface can be delivered at short notice. More information is available in our data sheet, which is available in PDF format (german only).

EA 9709-V24S represents a RS-232 interface with built in key inquiry for single keys/switches up to 5x5 Matrix keypad.

  • Bezels
    All bezels are available with an anti-glare screen. The bezels are simply inserted into the frontal cutout. This gives your unit a professional look, and at the same time the anti-glare screen prevents the integrated display from being touched or getting dirty. The anti-glare screen makes the display considerably easier to read. Please refer to the tables for dotmatrix modules for the order numbers of the various bezels. You will find more information on bezels in our data sheet, which is available in PDF format, or on our accessories page.
  • Inverters for CFL- and EL-foil illumination
    In contrast to LED illumination, CFL and EL illumination requires a series-connected electronic circuit. This electronic circuit, which is known as an CFL inverter and EL inverter, generates alternating voltage of some hundrets Volt from +5V DC. These inverters have 3-5 pins that are soldered into a printed circuit board. The type required depends on the illumination surface. You will find more information on our accessories page, our news page or in our data sheet, which is available in PDF format.
  • Cables and connectors
    We accept orders of one or more units of the following items for your display: one- or two-row connectors and cables with a grid of 1.27 or 2.54 mm with a female connector (one- or two-row) crimped on, with different numbers of pins and a wide range of lengths.
