RS485

Converters between bus RS485 and other data communication lines.

RS485 is resistant to the communication bus used mainly in industrial installations or in environments with requirements for high noise immunity.

RS485 (also known as two-wire RS485) uses only two wires, A and B, also known as RxTx+ RxTx- and more positive or more negative wire and cable. The line is half duplex, meaning that at one point, it can transmit only one side (the system of request - response).

The maximum length of one branch is RS485 up to 1200 meters. It can be extended by using repeaters. On one arm may be according to a maximum of 32 devices. Equipment must not be linking to the so-called stars (from all devices into one point), but gradually from one to another. As a jumper wire should be used twisted wire - Using their knowl perfect example of a twisted pair cable for the current computer network (TP cable).
