Great Potential, but has some quirks
For IEC62056-21 Optical Interface
This is a great optical interface, but it does seem to have some quirks that arent well documented. For example: The interface (due to reflections) echoes everthing back and some software cant cope with that.
Shipping was good, it came in a timely manner and in one piece...
The commuication though is ABSOLUTELY amazing. You send a message and not a day later you get a helpful reply, 10/10
