Hello !! :)

I tested during 2 days to put my Dreamcast PAL online..but impossible!!

For my config I have an :

Rpi 2
Modem Usb 56K Voice >> http://www.ebay.fr/itm/351812419185?_tr ... EBIDX%3AIT

Normally it's ok..it's voice capable no..? :shock:

I made 2 "Line Voltage Inducer"
One with a 12V Power and an other with 18V power.
And I tested with 2 capacitor 1uF different,ceramic and electrolytic)
Resistor 330 Ohms

So normally it's ok.

But I have nothing..nothing in Dreampi..and nothing on the dreamcast!

I made screenshot because Dreampi 1.6,tell me "unable to detect modem"...what!! ^^

Thank you in advance for your help !! :D :D :D

Hi!!! The RJ cable only will work at 18v, with one resistor and one capacitor. For me worked better 2x 9v batteries than a plug on the wall giving 18, but works to. Use a tester to check if the LVI is working good, if you get 18v or a bit more, you can be sure about that the 56kb usb modem is what fails.
Good luck!!! ;-)

Yeah that modem doesn't seem to be compatible with Linux. The description only says Windows.

"The RJ cable only will work at 18v, with one resistor and one capacitor"

Yes it's just I tested 2 config,with 12v and 18v,directly with power..

In fact when I test I have 18v both ^^

>> Use a tester to check if the LVI is working good

You are right with the tester, like they said, looks like that the modem is the problem. Thia is the model that i are purchasing now and works fine, 4 of 4 working. Is not in europe but in less than a month you will have it at home. If you find one similar on europe for less than 18€, buy it!!! Hhahaha.

France excluded? Omg sorry, this item is able to Spain, we are near. Dont mind, the important thing is the model, is cheap and works. I bought one to a netherland seller ago months. Sure that you find one on euro zone ;-)

Yes, i only used that and works really fine. Yes this not says linux compatible, that was a risk that i taked haha. Like i said, i purchased a total of 4 to diferent sellers and works ok.
