Guidelines for Proper Wiring of an RS-485 (TIA/EIA-485-A) Network:
Abstract: The proper method of wiring an RS-485 network is described, with recommendations for twisted-pair cabling and correctly locating termination resistors. Received waveforms are shown for examples of proper and improper cable termination. Configurations are shown for a simple, single-transmitter/multiple receiver network through multiple transceiver to multibranched circuits.
