buckshot23 Tl Posts: 2 USA | Posted - 12/8/2001 9:11:13 AM I am running windows xp I have the 56k 701 serial faxmodem. I connected it to com1 port with a RS-232c Cable. The modem lights up when I scan for hardware changes but it does not find anything. Also I am using a generic universal power supply set to 9V and 500 mA. The modem powers up fine but could there be interference with the power supply screwing things up. |
pauldog Tl Posts: 231 USA | Posted - 12/8/2001 10:36:31 AM My USR power supply is AC (not DC), and says "9v, 1000mA" so your 500mA may be underpowered. What I'm more afraid of is that your generic power supply is DC and you've damaged the modem. |
Bob Starnes Tl Posts: 4360 USA | Posted - 12/8/2001 12:20:38 PM I don't think that the 9VDC will hurt the modem but the USR external modem does require a AC power supply. Might verify the model number of the modem and check to see if you can find the specs on the modem to see what the correct power requirements are. |
pauldog Tl Posts: 231 USA | Posted - 12/9/2001 11:22:25 AM And unfortunately, the power requirements are probably not posted on the modem itself. I have a "Model 0701" 33.6 faxmodem sitting here (ID 000839-09), and it runs on 9v AC 1000mA. |
Bob Starnes Tl Posts: 4360 USA | Posted - 12/9/2001 2:00:57 PM Saw the power supply listing on USR's site one time but failed to bookmark it, haven't found it again since. There was a post on comp.dcom.modems at one time listing all the Sportster models: USR Part Number: Voltage: Model Number(s) 1.015.090-B: (Input 120VAC, 60Hz) (Output: 9.2 vac@533mA): 1.015.1202-B: (Input 120VAC, 60Hz) (Output: 20vac @750mA): 1.015.1286: (Input 120VAC, 60Hz, 16Watts) (Output 9VAC, 1000mA): 1.015.1443-00: (Input: 120v AC, 60 Hz, 21 watts) (Output: 9 volts AC, 1500 |
buckshot23 Tl Posts: 2 USA | Posted - 12/9/2001 6:59:45 PM thanks guys I think the power supply is the problem but I don't know where to get a replacement. I tried radioshack but I think they had DC adapters also. Thanks for the quick replies |
Bob Starnes Tl Posts: 4360 USA | Posted - 12/9/2001 7:54:07 PM Radio Shack does have some that are AC: Cat No. 273-1630 - 9VAC/780mA They've also got some for Nintendo game consoles, these are usually 9VAC/1000mA |
