Tom, There were two reasons I bought from Amazon, instead of ebay. First, I got it within 2-days w/Prime shipping, instead of two or more weeks from China. Second, it is easier to return things to Amazon. In fact, the first serial-Ethernet device I ordered had to be returned. It came with a bad power supply and even with a good supply, did not work. I felt that it was worth spending a bit more for these conveniences.
As for a multi-port device, yes, that makes sense. I'll see if I can find something similar on Amazon. What USB-Ethernet devices have you had good luck with? I am considering a somewhat expensive Silex device. I did buy a used Belkin-branded box that was made by Silex, but it kept disconnecting/reconnecting the USB devices. This seemed to be a common problem with this particular Belkin box. Joe Gray W5JG On Thu, Feb 25, 2016 at 1:38 AM, Tom Van Baak <t...@leapsecond.com> wrote: > Joe, > Thanks for that posting.
