LabVIEW
Connection beteween micrometer from mitutoyo and Labview.
Hi Oda,
when the connection is provided as COM port you should start using the "Basic Serial Read and Write" example VI. (Just use the ExampleFinder!)
And of course you need to read the programming manual of your Mitutoyo device…
Hi Oda,
I would look up for information on Mitutoyo's website or just call their support team…
Mitutoyo uses a special connector on their devices, that makes use of the interface without their cable a bit difficult. Since they are quite expensive high precision measurement devices (unless you bought one of the cheap chinese copy cats) I would hesitate to start doing some DIY soldering on the device itself. So not sure it is a good idea to try to interface these babies to a PC without at least their cable.
The actual Mitutoya data format while being some sort of serial data stream has nothing to do with RS-232 or any of the other common PC serial port interfaces. It is a proprietary one way TTL level interface where a digital clock of no more than 5kHz and the a 52 bit data blurp on the data line. To read that in you would either need to program a digital IO card from DAQmx, use a SPI or similar programmable interface, or connect it to a myRIO, or some Compact-RIO digital port. Alternatively there exist various more or less detailed descriptions on the net how people used an Arduino board to do the bit banging. A little TTL logic with a 52 bit shift register would work too.
This seems to be an early version of a the DigimaticCode Output I/F Specification that should be the one used in the Mitutoyo devices.
