Read data from Mitutoyo gauge

Question

I need to write a program that will read the data from the indicator once a minute. Unfortunately, I can not find the communication protocol for this indicator (the official representative responds extremely unqualified and there is no way to get at least some information from him). Some programmer (with whom I do not have a connection) wrote a similar program earlier, but did not leave the source code. In the Device Manager on computer the indicator is defined as USB-ITN. I will be grateful for any information in solving this problem.

Indicator model: ID-U1025M Indicator Serial Number: 13063340 USB cable: ITN - 60010409

Answer 2

I was able to communicate by using the driver bundled in the software USB-ITPAK . The thing is, that the driver installation is not straightforward at all. use the USB-ITPAK User's Manual(English) to get the instructions (Section 2.3 Installing the VCP Driver). One needs to follow the instructions to the letter - which refer to detecting the device in the device manager and installing the driver to each device - even if it is the same device!

Once the driver is installed properly - the connection will behave like a serial port - send the character 1 to get the measurement returned (for detailed communication command specification - check section 9.2).
