Eric Cathelinaud e.cathelinaud at googlemail.comI tried to short the left and to invert the twinax plug (thus pluging them as in the wiki) and it works too. Then it could be a mistake in the jumper plan of BN1E1 cause they say that the left is "TE" and not "NT". Anyone else dealing with a BN1E1 card to confirm?
