Apologies, but I seem to have got my wires crossed, the 3C8 is newer than the 5N0, with production started in week 22, 2011. Bummer, that's the problem trying to understand someone else typing English from a foreign language, lol.
Well seems like I need to sell the 5N0 then and re-order a 3C8.
Kalu, do you know if that will pair fine through the RNS?
