i just need to connect the 1 microfarad capacitors as shown in the datasheet and (in my understanding) the picture showing interfacing schematic between pin1 and 3 and like
Yes
do i need to simulate the inverter logic between pin 11 and 14 and like as well
No. The RS232 output is inverted, that inverter in the chip makes it alright.
do i short pin 11 to 13 and then connect that short wire to rx
No
i am positive many would actually be frustrated with the sort of questions
No
