does anyone have a diagram of mitutoyo linear scale (model AT112-one side is 9 pins round plug and the other is D connector 15 pins. )? I have it on my bridgeport and the cable is broken when it moved to my garage. thank you .

Did you ever get an answer, as I have a similar problem?

Hi,
I have got them here somewhere, I will find them over the next few days and post it up for you.

Thank you very much in advance!!!

Thanks for the reminder, I had forgotten.
I have the manual on these scales, and a lot of others, here are the pin outs.
If you need any more or other info let me know.

This is the actual connector:

[Davo J]

So it's 8 pin? How many wires are connected to it?
Also what scale number is it?

yes exactkt the 8 pin connector,

attached are the following colors:


red
orange
yellow
blue
green
brown

it is a AT112 scale\\I started a special thread for this : http://www.cnczone.com/forums/genera...at112-one.html


Thanks!

Thanks to Davo J I have found the colour codes for the Mitutoyo AT2-N scale. We had a cable with the same colours as SparkyNL with a round 6 pin plug pulled off. We sacrificed a connector from the scale on an unusable lathe in order to find which wire came off which pin. However, the wires in this cable were black, brown, red, orange and yellow. I buzzed these through to the connector pins and found they followed the resistor colour code, in that brown -1, red - 2, orange - 3, yellow - 4 and the exception black - 5.

Our readout has 9 pin D-type connectors so I had an adaptor cable from 6 pin round. Using this to find which pins of the D-type were connected to the 5 wires, I found the yellow wire was not connected. This left brown red orange and black - which from Davo J's list of signals is +5V, A, B and 0V which made sense! As there was no black in the cable I needed to connect, it made sense that they also followed the resistor colour code but used green - 5 for the 0V. I wired these to the D-type pins I'd found from the adaptor cable and sacrificed plug and the readout (z axis) was back!

For completeness the 4 wires connected to the D-type are: brown (+5V) - 7, red (A) - 6, orange (B) - 8 and green (0V) - 2.
