@john.m.keeling This is a good question. I’m unsure off the top of my head if we set a limit in the source code. As a quick test I was able to connect 4 devices simultaneously without any issues. However, please note that you can only record using one device at a time on a single PC.
Can you share more information about your use case and how many devices you plan to use with the software? If you need to connect more than 4 units, we can spend some time digging into the source code for you.
