Mitel 420 display pin-out DM052Z IBI.R6HB

I thought I would share the pin-out from a Mitel 420 16x2 LCD display. It uses the standard Hitachi 44780 chipset commands.

1 5 volts,
2 Contrast,
3 RS,
4 R/W,
5 E,
6 D0,
7 D1,
8 D2,
9 D3,
10 D4,
11 D5,
12 D6,
13 D7,
14 GND,

I called pin 1 on the side by where the ribbon cable connects to the glass. I searched all over and couldn't find any info on these displays, so perhaps this will be useful to someone.

Hi mate,

Hi mate,

Thanks for the info about the DM052Z IBI.R6HB I have one display I want to change same code and I was looking for info about it. I replaced it with another one but I don't have any luck with it. Where did you find the info about this DM052Z? Are you sure is accurate? I don't have any light or anything on my display after replaced it. I've done the soldering ok, double-checked.

Thanks

Sorry for the lateness of my

Sorry for the lateness of my reply. I had to correct an error about what I thought was pin 1 in my first post. I couldn't find any information about this display anywhere. I was able to get them to work from just by trying different hookups. It seems like the 44780 is the standard for a lot of displays.
