7 INTEGRA SERIAL COMMUNICATION INTERFACE
7.1 INTEGRA USB Serial Communication
7.1.1 INTEGRA USB Description.
The USB class used by Integra is a CDC, or Communications Device Class. This means it shows up in
the host PC as a com port, but to be very clear, it is not a com port. It is a true full speed USB port, you
can talk to it like it is an RS232 port, but very fast when it comes to speed. Follow the Windows Prompts
to install the USB drivers. The USB drivers are fully tested and digitally signed by Microsoft.
Open that port in your PC software with standard com port tools. None of the port settings matter as they
are not used, so leave them at whatever default they are in. It’s a real USB connection.
Use the standard com port writes and reads to control Integra.
