i recently aqquired a densitron 4x20 red inversed lcd to use with my project, but i cannot find a wiring diagram anywhere. it has one row of 14 pins with what looks to be a resistor soldered between pin 2 and the place where it looks like a pin 15 would be. i know densitron calls this wiring configuration PP1, but i cannot find the wiring diagram. the number on the back of the lcd is: 4420er-ct can anyone help me? thanks,
