FAQ:
Q: What is the difference between RS232 and RS485 communication?
A: 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. The PC is already equipped with RS232, which can be used directly.
Q: Is Modbus the same as RS485?
A: Is Modbus the same as RS485? The answer is no, because both of these are relative concepts that need each other in order to fulfil their purposes. Modbus defines the protocol type and RS485 defines the signal level on the protocol.
Q: What is RS 485 protocol?
A: RS-485 is a US-based telecommunications standard for binary serial communications between devices. It is the protocol, or set of specifications, that needs to be followed to allow devices that implement the standard to speak to each other. The protocol is an updated version of the original serial protocol known as RS-232.
Q: What is RS 485 transceiver?
A: What Is a RS 485 Transceiver? A recommended standard 485 (RS 485) transceiver is an integrated circuit that sends and receives digital signals directly between digital equipment, and uses positive and negative 5 volts direct current (VDC) maximum.
