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.

1.5 a is amperage rating not voltage rating;
The voltage you need is missing from the specifications you list:
You do not want to use an adapter that puts out DC voltage (an AC-DC adapter is not good); you need an AC adapter that puts out AC with correct voltage (I think it's something like 9vac).

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.

(Sportster and Courier modems are of different design and will not use the same power supply.)
