| apfreecycle Tl Posts: 1 USA | Posted - 4/30/2005 2:58:35 PM    Receieved this modem without an power supply adapter. Following are the details of the modem: 3COM U.S. Robotics 56k Voice Faxmodem Pro I emailed USR tech support and they informed me: "I understand that you need power supply specification for USR5605. Power supply specification for USR5605 is V AC 1.5A." I have a universial ac-dc adaptor, and the specifications on that are: Will this universial adaptar work with the external modem? I'm confused on which settings the tech support gave me. The "USR5605 is V AC 1.5A." I tried 1.5v and didn't power the modem on. I dont want to burnout or overload the modem, if anybody can please help me with this would be greatly appreciated. Thanks, allan |

| orava Tl Posts: 6 USA | Posted - 5/17/2005 9:10:53 AM I have Model 2806 External Courier V Fax/Data Everything modem that has a round 2-pole jace for the power supply input. This particular family of modems uses 20 VAC @ 750 mA. |
