Hi, I wondering about the USB versions. They have a caution in the docs about a power cycle, which causes the relays to switch several times during power up of the computer. This could cause some undesirable effects I would think. The serial and Ethernet do not seem to be affected. And, what is the difference between the serial versions which use a USB connector anyways? Any ideas? They do look good, with relays supporting 15a at 120 Tom
