I agree, and these devices are what I will use. I actually bought one from AX a few months ago,
but when I unwrapped it this week I found it to be an RS232 device, where the lines are probably
not bidirectional.

The device I highlighted in the question was different, it did not have active signal conversion
and I could not see how it is safe al all.
