If you read the Comments my ramblings sometimes attract you’ll see that “USB3 Vision versus GigE Vision” drew some questions. As the writers took the time to read what I had to say I’d like to pay them the courtesy of a reply.
First off, I should have cited my sources. Most of my information came from the Basler paper referenced in “Understanding USB3 Vision” although I did pick up a few other points from Stemmer and others. Regrettably, I didn’t save the links but if you Google “Advantages of USB3” or some similar phrase you’ll find the pages I used. Lesson learned.
And now, to the questions (or should that be answers?):
- Regarding USB3 cable length – yes I’m sure you can use repeaters but everything I’ve seen says the effective limit is around 3m.
- On cable security – I meant the provision of screw-in connectors, but I also included immunity to noise. It’s my understanding that USB3 cables offer superior construction in this regard.
- On how I calculated the CPU load scores for USB and GigE – confession time – I didn’t calculate anything. It was a subjective assessment again based on what I read in the Basler paper. In my defense, my intention was to highlight relative strengths and weaknesses rather than assign absolute scores, and I think I accomplished that.
If anyone has any different information that runs counter to what I’ve said, I’d be glad to hear from them.
