RS485 communication line in the general use of twisted pair can be, but in the higher requirements of the environment to use with shielding layer of twisted pair cable. When RS485 communication line is used, for a specific transmission line, the length of the cable between the host (call test equipment) and the meter is inversely proportional to the baud rate of data signal transmission; This length is mainly affected by signal distortion and noise. Theoretically, the transmission distance of RS485 communication cable can reach 1200 meters, but the transmission distance in practical application is less than 1200 meters, and the specific length is affected by the surrounding environment.
RS485 communication cable features: RS-485 communication cable features impedance of 120 ohm, conductor of 2*24AWG multi-strand stranded tinned copper wire, PE insulation medium, by aluminum foil/polyester composite with 100% coverage + tinned copper wire 90% coverage of a total of 2 layers of shielding, with independent grounding wire, industrial gray PVC outer sheath.

The tested RS485 communication line communication distance is about 1219M, the transmission rate is 10Mb/S, the transmission rate and the transmission distance are inversely proportional, under the transmission rate of 100Kb/S, to achieve the communication distance, if you need to transmit a longer distance, need to add 485 repeater. RS485 bus generally supports 32 nodes, if the use of special 485 chip, can reach 128 or 256 nodes, can support to 400 nodes.
Because RS485 interface has good anti-noise interference, long transmission distance and multi-station ability and other advantages make it a serial interface. Because RS485 interface composed of half duplex network, generally only two connections, so RS485 interface are shielded twisted-pair transmission.
