Working Principles

The MAX487CSA+TG002 is an RS-485/RS-422 transceiver that enables reliable data communication over long distances. It uses a balanced differential signaling scheme, where the non-inverting and inverting signals carry the transmitted data. The driver enable (DE) and receiver enable (RE) pins control the direction of data transmission. When DE is high and RE is low, the device operates in the transmit mode, allowing data to be sent from the A and B pins. Conversely, when DE is low and RE is high, the device operates in the receive mode, enabling data reception on the A and B pins.
