if yes haw can i modefay thise cable or make a new one?]]> Fri, 09 May 2008 02:06:54 -0700 http://www.8051projects.net/forum-t9410.html Re: replacing data cable for mobile http://www.8051projects.net/forum-t9410.html I have the same problem with my project and I need help too
the phone is nokia 6100 and I have tried many commercial cables (serial ones) with many programs but only logomanager and oxygin did work
I need the phone and the cable to work with hyberterminal to be able to send AT-commands from the hyper to the phone, so I tried to make a homemade one but till now it does not work it is still under test
the circuit and the explanation in the following link;

But I hope if any one has any experience with that please help]]> Eng_Z<az_20002@nospam.com> Sat, 10 May 2008 09:55:53 -0700 http://www.8051projects.net/forum-t9410.html Re: replacing data cable for mobile http://www.8051projects.net/forum-t9410.html Do you have any experience with that ?
and if you have (I hope you have) Does the above circuit work with AT-commands?

Waiting your reply,,]]> Eng_Z<az_20002@nospam.com> Sat, 10 May 2008 10:22:39 -0700 http://www.8051projects.net/forum-t9410.html Re: replacing data cable for mobile http://www.8051projects.net/forum-t9410.html Ajay<contact@nospam.com> Sun, 11 May 2008 16:26:47 -0700 http://www.8051projects.net/forum-t9410.html Re: replacing data cable for mobile http://www.8051projects.net/forum-t9410.html Thank you for your reply, I will try that soon and I will tell you the results
but what if we make a voltage divider at the RX of the phone to convert the 5v of the micro(Atmel8515)to 3v that because I knew that the phone (6100) voltage level is 3v
does the 5v harm the phone?

thank you]]> Eng_Z<az_20002@nospam.com> Sun, 11 May 2008 22:45:58 -0700 http://www.8051projects.net/forum-t9410.html Re: replacing data cable for mobile http://www.8051projects.net/forum-t9410.html surely a voltage divider is needed. phone is more important ]]> Ajay<contact@nospam.com> Mon, 12 May 2008 15:14:08 -0700 http://www.8051projects.net/forum-t9410.html Re: replacing data cable for mobile http://www.8051projects.net/forum-t9410.html Ajay wrote ...

well just limit the current using resistor and surely a voltage divider is needed. phone is more important


Does limiting the current with a resistor means the voltage divider or voltage divider is something else?]]> say2paul<say2paul@nospam.com> Wed, 25 Jun 2008 04:23:00 -0700 http://www.8051projects.net/forum-t9410.html Re: replacing data cable for mobile http://www.8051projects.net/forum-t9410.html
voltage divider is when you divide voltage using two resistors..

|   V1 |   V2 |
|/\/\/\|/\/\/\|
  R1      R2

V1 = R1 * (Vtotal/R1+R2)
V2 = R2 * (Vtotal/R1+R2)
