ok, now about the serial interface. i have used an Renesas developers board with an M16C28 microcontroller on it. that's just because i already had this one at home. basically you schould be able with almost every microcontroller to drive the display. what you need is an serial connection to PIN 4 from the 10 pin Herose connector. the baude rate is 2400. in theory this is a duplex communication, but the monitor will never reply.
the protocoll for commands can be seen in the 3 other attached pictures. basically it is a data word which is repeated every 100ms. the content of this word will lead to an action on the screen.
the data word consists of 5 x 10 bit which are seperated by one low bit.
bit nr. 10 is the parity bit which brings the parity to even.
the first byte are something like a start bit. everything in between will set the screen. you can see in Auswertung_3.jpg that the 3rd byte is used for dimming. there are 10 stated for 10 dimming states. within the same byte there is one bit which is always the same except at the first state (Nach Schlüssel AN). with this bit you can suspend the monitor. it will stay open, but is black.
the 2nd byte is for poping up/down the screen. if you just stop sending any commands, the monitor will close after 30 sec or something."
