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
