MAX232
Ready with mine hand made MAX232,to be added with GPS and serial to USB convertor.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).
