OK guys, let me get this straight. Obviously the segs ABCDEFG are correct
since the numbers display correctly.
I have 10 common catode wires , one for each digit.
which go to the DISPLAY CARD (I had never done this before!!. Iwas amazed
that it somehow worked) so to make shure, wire No. 1 now becomes No. 10
and so on?? .
Thanks for the help.

I would suggest that
If you are defining one 3 digit display, I would suggest you do it like this.
1 becomes 3
then when you add the next say a 4 display definition, then 4 would be 7 5 would be 6.
does this make sense to you?Last edited by Trevor Hale; 05-28-2008 at 09:35 AM.

Actually afte a bit of thought it should be flipping wires 1-5 for
the first group and and 10-6 in the other, right?

that would be correct if you are going to group the 10 into teo. I am not familiar with the 7 segment board your using, all I can say is that if your using a function that has 3 Digits, then your #3 has to be your Most significant bit, and your #1 would be your Least significant Bit.
By the sounds of things the board is wired so that #10 is your MSB and #1 is your LSB you need to keep this true when your wiring. Your documentation should tell you what is what...

Yes, It looks like that. I had very scant information for this board which
handles 5 digits. It sounds they are reversed. I'll work on it
tonight and feed you back.
Thanks.

Switched the common cathode cables, now it
works well. Thank you.
Has anybody worked on the Electrical display panel?
Regrads to all.
