Accessories

• EA 017-xxU series
  The bezels of the EA 017-xxU series are made of black ABS material to UL 94 V0 (up to 100°C, self-extinguishing, non-combustible) with a scratch-resistant, structured surface. They contain a snap-in mechanism for mounting of plates with a thickness of 1mm. The plates can thus be easily replaced, as required. A front plate can also be delivered with the specified bezels (clear plexiglass, anti-glare plexiglass or glass).
• EA 017-xx series
  The bezels of the EA 017-xx series have a matt black, coated surface and an undercut at the back for sticking on plexiglass plates with a thickness of 1-2mm. The specified bezels can be delivered optionally with or without a fitted plexiglass plate.
• EA 027-xxKE series
  The bezels of the EA 027-xxKE series are made of anthracite-colored ABS material. They are delivered exclusively with a replaceable, anti-glare plexiglass plate. They are delivered in packs of 10.

Many dot-matrix and graphics LCDs have only one option for connecting to an 8-bit data bus. If the data is to be transmitted serially (lack of ports, considerable distance), it is advisable to use an RS-232 interface. This interface then also handles the initialization and line management of text displays. Using an interface also considerably reduces the programming effort required with graphics displays as well.
 

• RS-232 interface for dot-matrix displays
  The EA 9707-V24S board is suitable for all dot-matrix LCDs with HD 44780 (1x8 to 4x40 characters). It is a mere 80x32x14mm in size. The RS-232 connection is provided by a 10-pin connector, and there are 3 different 1- and 2-row soldering-eyelet strips available for connecting the display. The transmission rate can be set to 300, 1200, 2400 or 9600 bps. There is a contrast potentiometer on board. The supply voltage is +5V or +9-35V. You can download the full data sheet in PDF format here immediately. The price if you order 25 is 44.37 euros*) per item. An RS-422 interface and an integrated fixed-text memory for 64 pages with 6 digital inputs are available as options.

• RS-232 interface for graphics displays
  We can provide a suitable RS-232 interface for practically any graphics LCD in our range. We also offer some displays as fully configured graphics units. The different displays have resolutions of between 120x32 and 640x480 pixels. Each interface has a variety of integrated fonts and graphics functions that considerably simplify graphics programming, which can otherwise be really quite complex.
