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 SUB-D connector of a PC, for example, via the EA KV24-9B cable (approx. 1.50m).
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.
