in addition to the 2 you mentioned there there are numerous other ways to transfer data serially, but the main I think would be USB.
RS232 DB9 connectors Receives data serially from Pin No. 2 & Transmits data from Pin No.3.
rs232
rs232 isfaster than rs449
Different data rate speed (for rs232 is lower), usb is more flexible and takes less energy. Different instructions and commands. If you are a programmer then it's easier for to work with usb then with rs232.
Yes, you can get a USB to RS232 converter (aka USB to Serial).
Difference between Rs232 and RS485 is Only Distance RS232 is not for long or far distance .. but RS485 can be use for LONGEST distance ..RS232 is single ended communication where as RS485 is Differential communication.Max.no of receivers in RS232 is only ONE, whereas in RS485 is 32.Max.no of transmitters in RS232 is only ONE whereas in RS485 is 32.IN RS232 there is no pin to change from transmitter mode receiver mode. But, In RS485 have DE pin to set transmitter mode and RI to set receiver mode.
One can purchase a RS232 cable at most electronic stores. A few common examples of stores that have RS232 cables for sale are Best Buy, Radio Shack, and Fry's.
RS232 means "Recommended standard no. 232", EIA standard for serial communication Thirumalesha.....
It can be either.
The difference between max232 and rs232 is the voltage levels of the rs232 are high. In order to reduce those voltage means to convert those voltage levels to TTL logic levels we use max232 integrated chip which is a dual driver/ receiver.
Because R2D2 was already taken!
i think its 96000BPS
