3Com U.S. Robotics 56K Voice Faxmodem Pro power adapter help...

[apfreecycle]

Receieved this modem without an power supply adapter. Following are the details of the modem:

3COM U.S. Robotics 56k Voice Faxmodem Pro
Model number is: 0525
FCC Reg.No. : 4X2USA-32128-M5-E

I emailed USR tech support and they informed me:
Thank you for choosing U.S. Robotics.

"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:
model: 900-100
input:100/220v 60/50Hz
Power: 18 W
Output: 1.5.-3-4.5-6-7.5-9-12V
Current: DC 1000mA max

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

Thats weird. They said 1.5a instead of a voltage value, so 1.5 volts isn't in Amps.
The modem could easily use 12v though i wouldn't want to tell you to do this as it might damage it if i'm wrong.
I would step up slowly, as one of those have got to work as there are standard values. I doubt it would be 1.5v since this could be powered by an AA battery...

Hope this helps

Well...

Look where the power pack plugs in see if the embossed info is there. If not you can go to us robotics and download the specs on that modem. I checked the numbers you gave and they have the specs on that one but the file is 2 megs.
