Digital panel meter (LCD)

[dratomic]

Hello,
I just picked up some LCD digital panel meter modules
from the local surplus store and I could use some help
in identifying them before I resort to disassembling one.

It consists of a meter module mounted on a PC board.

The modules have a 9 pin ribbon cable connector on the
rear of the meter (PC) and the front of the PC board it's
mounted on has the number "RC0007 Rev C" silksereened
on the front. The LCD unit is mounted on the board with
an LED in the upper right corner. The module itself has
36 pins grouped as 2pins 7 pins 7 pins 2 pins along the
top and bottom of the actual module. I am assuming it
is a volt meter since I can see the words "test" "b3" "cal"
"5v" and "bat" silkscreened on the actual board next to the
pins. Any clues? It appears to have 3 1/2 digits and some
other items on the display itself. The fromt side of the board
it's mounted on (the one with the 9 pin connector) has the
word "DPM1" silkscreened on it. Any help would be appreciated.

Since no one is replying I guess no one knows anything about
this unit I'm pitching them in the trash.

Finally got it!!!!!

I finally found out what these things are. They turned out to
be DPM2000 Digital panel meters. Really versatile. Glad I didn't
have to resort to destructive analysis of it. The things sell for
about $50.00 each and I got them for $2.00!!! I'm really glad
I didn't just pitch them.
