What is rsrs-485?

What is rsrs-485?

RS-485 has been created in order to expand the physical capabilities of RS-232 interface. The serial EIA-485 connection is done using a cable of two or three wires: a data wire, a wire with inverted data, and, often, a zero wire (ground, 0 V). This way, transmitters and receivers exchange data via a twisted-pair cable of 22 or 24 AWG solid wires.

What is the difference between RS-485 and RS-422?

In industry, the most common interface is RS-485 (EIA-485), because the RS-485 uses a multi-point topology, which allows you to connect several receivers and transmitters. The RS-485 interface is similar to the RS-422 in that it also uses a differential signal for data transmission.

What is the voltage of an RS-485 connector?

The voltage on the lines is in the range from -7 V to +12 V. The RS-485 standard does not define a specific type of connector, but it is often a terminal block or a DB9 connector. The pinout of the RS-485 connector depends on the manufacturer of the device and is specified in the documentation for it.

Can RS-485 run in full-duplex mode?

RS-485 can run in full-duplex mode and when it does, it essentially becomes RS-422. In fact, you can often take hardware utilizing RS-485 and successfully drop it into an RS-422 setup.
