Hot New Products Explosion-Proof Handheld Portable Ozone Gas Detector - Bus transmitter Instructions – Huacheng
485 is a kind of serial bus which is widely used in industrial communication. 485 communication only needs two wires (line A, line B), long distance transmission is recommended to use shielded twisted pair. Theoretically, the maximum transmission distance of 485 is 4000 feet and the maximum transmission rate is 10Mb/s. The length of the balanced twisted pair is inversely proportional to the transmission rate, which is below 100kb/s to reach the maximum transmission distance. The highest rate ... -
