So for my project i am ready with a handmade MAX232 circuit.
One more step close to my project but still very far away
Some information regarding MAX232 from its datasheet.
Meet or Exceed TIA/EIA-232-F and ITU
Recommendation V.28
Operate With Single 5-V Power Supply
Operate Up to 120 kbit/s
Two Drivers and Two Receivers
±30-V Input Levels
Low Supply Current . . . 8 mA Typical
Designed to be Interchangeable With
Maxim MAX232
ESD Protection Exceeds JESD 22
– 2000-V Human-Body Model (A114-A)
Applications
TIA/EIA-232-F
Battery-Powered Systems
Terminals
Modems
Computers
As RS232 is such a common protocol there is a dedicated IC designed for this purpose of "Level Conversion". This IC is MAX232 from Maxim. By using charge pumps it generates high voltages(12V) and negative voltages(-12V).
and a little bit of soildering practice.
