Dotmatrix Standard Modules

RS-232/RS-422 controllers

The EA 9707-V24S interface allows dot-matrix LCDs to be programmed easily and quickly. The interface can be soldered directly onto almost all dot-matrix 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. The interface can also be supplied with an RS-422 interface (EA 9707 OPT-RS-422).

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 net. Smaller quantities of the interface can be delivered at short notice. You will find more

• Bezels
  Bezels with an anti-glare screen are available for some graphics displays. The bezels are simply inserted into the opening in the front panel. 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 above 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 EL foil illumination
  In contrast to LED illumination, EL foil illumination require a series-connected electronic circuit. This electronic circuit, which is known as an EL inverter, generates alternating voltage of around 100V from +5V DC. These EL 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 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.
