I am looking around for info related to SPC and how to build a remote
display. I haven't found much yet. Does anyone have pictures,
plans, links, or ideas on how to do this?

Thanks,
Jamie

When you say digimatic do you mean the Mitutoyo scales or the
cheap imported ones?

The import ones.

I have 2 Mitutoyo Digimatic #982-537 displays that I would like to use
with the cheap generic scales because of the application. I have some info
on using Starett scales with Mitutoyo Displays but nothing on the other.

Ok, I put a file in the files section that should help anyone who wants to
use the SPC port on the imported digital calipers and scales.

The file is called "Caliper_stuff.zip" under "Imported_Caliper_Info".

If anyone has any other questions about interfacing to these units I would
be happy to help.

Have fun!

Hey all,
The caliper_stuff schematic has a diode backward going
from the input of the comparator to ground. The cathode
should be pointing to ground. This is an older schematic
I did awhile back. Also some versions of that code used
serial output to the PC and others parallel. It was a
case of 'I found out enough to get the job done, than
went on to other stuff'. If I can answer any questions,
let me know.

Wow, that is some good info, thanks. I have read that the import
scales, such as those from JTS, use a completely different SPC format
than the Mitutoyo scales. Is that true? If so does that mean the
info here will not work?

Thanks,
Jamie

Hi,
Yes, digimatic and 'SPC' are different specs, SPC is
often proprietary and not well defined for the customer.
I used a digital storage scope and examined the outputs
at 1.00" and 0.00" to figure out the generic
SPC format used in the cheaper calipers I've
found on Ebay.

You could use a micro to translate between the
two specs. The files section has info on digimatic
also and some PIC code:


Hope this helps and have fun,
Lee

Has anyone built a purpose-made box for displaying the output from this type
of caliper? I'd like to avoid using a computer if possible.

John

WTTool makes a 3 axis one for $250. I'm working on a design for a 2/4
axis display but it's kinda stalled right now. I'm trying to find a
source for off the shelf membrane keypads.

C|

Would you happen to have wiring diagrams that could use regular momentary
switches rather than membrane keypads?

John

Hi!
From what I know, it shouldn't be any difference in wiring of momentary
swiches compare to the membrane. In fact you can make membrane out of
momentary by soldering momentary switches into the rigid PC board ,
putting spacer and glueing an overlay on top - you get membrane switch.

Not at all. Membrane switches ARE momentary. The reason I wanted to use
membrane switches is that I figured they would be more oil and chip
resistant.

The idea of of making my own did occur to me but I didn't think about it
all that much. Now that you mention it you could use some of the wide
flat PCB mount "tact" switches and just stick some kind of plastic
membrane over the top. Hmm, yeah, I think this could work!

Umm, well sort of. I have a partial schematic but it's not complete. I'm
using an Atmel ATMega8 MCU to decode the data stream and display the
numbers on an LCD. The type of switches doesn't really matter as long as
they are momentary.
Also the code isn't complete either. When I get this thing closer to
completion I'm planning on putting it all up on the web. Hopefully that
won't be too long from now but it's hard to say.
