Luis, Looks like the same connector Hayes used to use on their old Smartmodems. Wallwart put out 13.5 VAC and had a ground pin. Middle pin on connector is connected to ground pin on wallwart. Wallwart I have says "Made in Hatti". Threw the modem away a long time ago. Hope this is of some help. -Frank Frank Richterkessing FRANK.RICHTERKESSING@APPL.GE.COM > |<--10mm--->| > ------------- > | O O | Height is 10mm > | O | > \_________/ > > >
