WebFrom the RS-485 specs: transducer should make at leas 1.5V signal at its output; receiver should receive a signal at least 200 mV on its input; This leads to the conclusion that, 150 Ohms of series resistance (or greater) will not guarantee that the signal will be received. WebSep 24, 2024 · RS-485 (also known as TIA/EIA-485) is a standard interface for physical communication. It is a form of serial communication. Typical serial communication standards are RS232 and RS485. RS485 expands the physical function on the basis RS232 interface. RS-485 adopts balanced transmission and differential reception, so it has the ability to ...
