RS485 Shield for Arduino is an industrial standard for long distance, anti-interference and reliable communication. It is especially designed for the Arduino controller board. It converts UART/serial protocol to RS485 protocol. This RS485 board allows Arduino access to industrial standard protocol easily. In contrast to RS-422 which has a single driver circuit which cannot be switched off, RS-485 drivers use three-state logic allowing individual transmitters to be deactivated. This allows RS-485 to implement linear bus topologies using only two wires. The equipment located along a set of RS-485 wires are interchangeably called nodes, stations or devices. Besides Tx/Rx interface, there is a switch to block/disable this shield, when Arduino needs to be programmed.
