Unknown LCD module not HD44870

[johnyp]

Hello to all. I have two lcd modules with 6pins so not HD44870 compatible but maybe rs232. My problem is that i can not find anywhere the datasheet. They are from VL and model is OK001 that is all they have printed. Does anyone has any idea ? Thank you

quoted "OK001" isn't a LCD display, it's an optical M-Bus interface, e.g. to use with a PC. The manufacturers catalog doesn't suggest that the display is one of their products.

My lcd has 6 pins and that datasheet mentions 7 pins. I don't think that will do. I don't speak German also.Any other info ? It has to be rs232 lcd cause i took it from a tax signature printer.

check the last few pages of data sheet.... its is english and they have given rs232 connection pin outs of the device...

Pins 4 and 7 power supply + ????? But how when lcd has only 6 pins! It is not that lcd.

LCD comes in 6 or 8 pins.. if it is 8 pins then 4 and 7 are VCC ( 1 for LCD and other for Backlight) but here only 1 vcc is enough if internally shorted so pin 7 may be ignored......

And what about pins 1 and 6 ? Unused ?
