The RS-232 standard was originally developed at Bell Labs in the early 1970s, when the phone company owned all the phone lines, internal and external, and every piece of equipment connected to those lines (e.g. phone, fax, modem, PBX, hotel switchboard), you just leased the equipment. The purpose of RS-232 was to provide a standard for connecting a phone company owned modem (DCE) to a customer owned terminal (DTE). This would allow the customer, using his terminal, to connect to and login to a remote timesharing computer mainframe.
The original standard used 25 pin "D" connectors (DB-25), one male one female, but has since been modified to also permit 9 pin "D" connectors. Users frequently deviate widely from the standard as they are connecting to neither modems (DCEs) nor terminals (DTEs) and use different connectors or use signals in ways not described in the standard.
RS232 means "Recommended standard no. 232", EIA standard for serial communication Thirumalesha.....
Data Terminal Equipment (Serial)
rs232
RS232 is a communications protocol for electronic devices to exchange information
rs232 isfaster than rs449
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.
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
