US Robotics Courier V.Everything with V.34

I have an old US Robotics Courier V.Everything with V.34 external modem.  I'm told it is a model 1224-00.  It's an older modem, but it looks just like this newer 3453B:
http://www.usr.com/support/product-template.asp?prod=3453b

Two questions, the minor one first:
1. The wall wart AC adapter is gone, but I'm pretty sure it was a 20VAC 500mA.  (Incredibly, the info printed on the bottom of the modem doesn't identify the power requirements.  I think the AC adapter was a "USR-20 1.015.1202".)  Any good ideas on how to snag a replacement?

2. This old thing was a pretty good commercial modem in its day, with upgradability and stuff.  Can it be upgraded to V.90 or V.92?  (The USR Upgrade Wizard application won't help me because I don't have the AC adapter, so the Wizard can't "see" the modem.  I don't want to bother buying a replacement wall wart if the modem can't be upgraded.  What a catch-22.)

Thanks.

Seeing as no-one else has answered here's my tuppenceworth:

Open the case (I assume it's well past its warranty) look at the circuit board - it 'may' quote the incoming Voltage. otherwise, and I take no responsibility for blown hardware here. Use a multi-voltage PSU and starting at say 3v up the voltage until you get a good response -**Remember here that many cheapo multivoltage PSU's will tend to output more V's than stated.

Most of the older USR external modems did take the 20 volt adapters, the newer ones take a 9 volt adapter.
<< Any good ideas on how to snag a replacement? >>
Ebay is a good source.  Ratshack, err I mean radio shack may have a universal adapter.

Thanks so far and everything; the second question is really of more interest to me...so here's some more points.
The model number you gave is not listed as valid, maybe there is a different model number somewhere on the modem?
Maybe an international modem? if so then it is not upgradable.

Can you just borrow a PS from a friend who has an external USR modem? or maybe from the local friendly computer store?

At this point there is no way we can say for sure if your modem is upgradable with the info you have provided so far.

Look at this link for more info:
http://www.usr.com/support/drivers-template.asp?prod=s-cour
Query your modem like this:

Click Start and go to the Control Panel.
Click the Phone and Modem Options.
Click the Modems tab.
Click the Properties button.
Click the Diagnostics tab.
Click Query Modem.

You will see something like this
ATQ0V1E0 -
AT+GMM - HSP DATA/FAX MODEM
AT+FCLASS=? -
AT#CLS=? - 0
AT+GCI? - +GCI
AT+GCI=? - +GCI:(B5,3D,04,59,A5,B4,00,0
ATI1 - A97
ATI2 -
ATI3 - PCtel HSP56 MicroModem 8.00-9K
ATI4 - PCtel HSP56 MicroModem Data/Fax
ATI5 - V.9
ATI6 - XP.0
ATI7 - P0011.0


This will tell us what your modem is and what it can do - You could give us the FCC code?

How can he query the modem when he doesn't have a power supply? Half of the question was about getting a PS, the other half was about was it upgradeable or not and he doesn't want to get a replacement PS if it is not.

rayt333 - See my earlier posting about the Power Supply Issue.

Oh BTW rayt333, I found most of the above by doing a 'ggogle' search. Good tip that one, mate - I won't forget it <vbeg>

Peace
And the erroneus remark about UK frequency was of course intended for another question.

So just get a 20v PSU with about 500mA draw
(use the links to contact the manufacturer for clarification on exact rating, but 500 will be OK I guarantee it), and get a sparkie to hard-wire it up for you.
s_turner99
The upgrade is not free, it costs $60 (US) and the replacement PS will run in the $15 to $20 range (unless you get lucky and find unneeded spare one)
Are you sure the modem even works?
the question you need to ask yourself is "Is this worth it?"

As an example I checked current auctions on Ebay and there is several 56K Courier V. Everything modems at buy it now prices of under $35.
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3468201845&category=51057
Here is one like yours (same model number) that has a buy it now price of $25 and starting bid of $10 with very little interest in it so may go for the minimum bid amount. It even includes the PS.

Please read my third link I posted above:
http://homepage.ntlworld.com/tim_n_clarke/comms/usr_modems.htm

  You'll find the models costing $60 for an upgrade are listed. And yours is plainly not one of those, as the article goes on to explain.

rayt333 how come you said to me:
>Half of the question was about getting a PS, the other half was about was it  >upgradeable or not and he doesn't want to get a replacement PS if it is not.

 I thought my 'fix' was OK? So why the move to try to get him to buy one ?

We may as well open up a shop?

lLove n Peace

Why do you feel I need to explain all my comments to you? If the questioner needed an explanation that is OK, but this is the second question you have bugged me on. Is this really nessesary? Can't you bother someone else for a while?

OK if you really can't figure it out, I was trying to show  s_turner99 the cost of buying another modem as opposed to upgrading an unknown condition modem. Why waste money on a PS when you could buy a working modem for only a few dollars more (and still have the first one as spare if needed)
Maybe I was just getting my own back for the totally uncalled for outburst at me whilst cleaning old questions?
Anyhow lets forget it now and get back to the answers.

Peace
Thanks for the effort, folks!

HippyWarlock provided the best info for me to know if the modem is upgradable.

And rayt333 was the first one in with the power supply verification.

(Note that before I even posted this question I googled all over the place and even wasted some time on the phone with USR.  The only number on the bottom of the modem is 0012240044211311, which is apparently a model number plus a serial number jammed together.  At first the USR guy told me it wasn't even a valid number, then he did more searching and told me it was a model 1224-00 and that replacement power supplies are no longer available.  I will have to find one at Radio Shack or perhaps somewhere online.)

thanks again.
There does seem to be a degree of confusion on their website too, unfortunately this is what happens when a product starts to age, the company withdraw from it and links get harder to find/fathom out.

Good luck anyhow
I've got a ps that'll work. I snagged a couple of them from a local elec surplus outfit and tested them.
I bought a 002806 off of eBay, bare also, from a Vegas pawn shop. Arggh.
I bought it for a buddy. I haven't gotten it working and it's been a long while since I fooled with, so this thread interests me.

The modem will work with almost anything between 10v and 20v ac from what I've gathered. These are both 18v and over, they're supplies from some Texas Inst peripherals. I've swapped the output plugs, they're 2.5mm IIRC. Max 1.35amp.
