FAQ:
Q: What is the difference between RS-232, RS-422, and RS-485?
A: RS232 is full-duplex, RS485 is half-duplex, and RS422 is full-duplex. 2. RS485 and RS232 are only the physical protocol of communication (ie interface standard), RS485 is the differential transmission mode, RS232 is the single-ended transmission mode, but the communication program does not have much difference.
Q: What is the difference between RS422 and RS485?
A: The RS485 Standard is similar to the RS422 standard upon which it is based. The main difference is that up to 32 transmitter receiver pairs may be present on the line at one time. A 120 Ohm resistor should be used to terminate either end of the main line.
Q: What is RS232 cable for?
A: RS232 cable is used for serial communication between computer and other equipments such as: modem. printer. scanner. other electronics systems not in category of computer peripherals.
Q: What is a RS485 connection?
A: RS-485 is a multipoint communications standard set by the Electronics Industry Alliance ( EIA ) and Telecommunications Industry Association (TIA). RS-485 supports several connection types, including DB-9 and DB-37.
