can u please explain me about rs-422 and diff between 485 and 422?

 

RS485 is 2 wire (plus a common reference) while RS422 is 4 wire (plus a common reference). Most devices that support RS422 4 wire can also be wired to be RS485 2 wire. With such devices you jumper TxA to RxA and TxB to RxB for RS485 2 wire operation.

 

You need to purchase a RS485 4-Wire to RS232 converter. Depending on your computer requirements you could also use a USB to RS485 4-Wire Converter.

RS485 can be configured in a 2-Wire or 4-Wire configuration. You will need to confirm that the converter supports both configurations for maximum flexibility.
