I regularly use the 9 pin serial ports on my pc for bringing in external data. Can anyone confirm that USB ports are already opto-isolated?
Not certain; but you can get optoisolated USB hubs.
I use both win2k and linux fedora but didn't thnik the os made any difference?
thanks diodorus. I know I can get isolated hubs but thought i'd heard that ports themselves were isolated. could be wrong i suppose - why else make isolated hubs?
No, the OS doesn't make a difference here. Only google might be able to give an answer one way or another I suppose...
Thanks Dio. I'll keep looking around.
