what a joke at this price
but i must admit, they permit you to CAL the unit directly if you have a reference source ....
very high baud rates speed
a few goodies, but hard to justify this pricing for me
they should be honest from the start they use FTDI drivers it seems, instead of a no name driver package loll have to read their spec sheets
and i would have made some provision say, 2x external relays controls pins, say to provide 200v and 1kv input, just add precision dividers and tvs / gaz tube discharge etc ...
