Hi guys, Tnx to those that responed. I moved the tnc over to the old pooter and it worked FB. The problem was me! The wall wort I was using was a 12v AC wort not 12v DC. TNC in Logic is just fine with a DC supply. Getting old must make a person dumb! Thanks again and sorry for the dumb posting. LOgic is the best there is . Bob k5sit 73 es gud dx cul.
