軟件解紹 RS-485網絡通信電線電纜電線線在似的的場所用到雙絕緣線就不錯，但在耍求很高的工作自然環境下不錯用到帶手機屏蔽層的雙絞電線電纜電線線。在操作RS485網絡通信時，就其他的網絡接入路線，的設備主機（召測的設備）到儀盤表的485口間的電線電纜電線線粗度與的數據數據信息網絡接入的波特率反比；這種粗度一般受數據信息的偏色甚至噪音污染的關系所關系。基礎理論上RS485的網絡接入距里能達標1200米，但事實上應用領域中網絡接入距里要需小于1200米，到底粗度受四周圍的工作自然環境關系。 RS-485 communication cable in general occasion using twisted pair can be, but under the high requirement of environment can be using tape shielded twisted pair cables. When using RS485 communication, for specific transmission lines, the host (called measurement equipment) to the meter 485 ports between the length of cable and the data signal transmission baud rate inversely proportional; the length is mainly affected by the signal distortion and the influence of the noise influence. On the theory of RS485 and the transmission distance can reach 1200 meters, but the actual application in the transmission distance is less than 1200 meters, the length is influenced by the environment around. www.hejindianlan.com//www.anhdl.com 在低擋、短距離、無干憂電磁波的學習環境會選用普通級的雙銅編織線，相反、，在迅速、短線接入時，則還要選用阻抗搭配搭配(般為120Ω)的RS485用資料線(STP-120Ω(for RS485 & CAN) one pair 18 AWG)，而在干憂電磁波學習環境惡劣的學習環境下還應選用鎧裝型雙絞手機屏蔽資料線(ASTP-120Ω(for RS485 & CAN) one pair 18 AWG)。在用到RS485接口協議協議時，對于那些特定的的接入配電線路，從RS485接口協議協議到裝載其資料電磁波接入所合法的很大資料線長寬高與電磁波接入的波特率關系不大，整個長寬高資料通常是受電磁波失幀及噪聲污染等的會影響所的會影響。系統系統論上，網絡通訊速率單位在100Kpbs及下述時，RS485的最高接入距離能夠能達到1200米，但在現實應用領域中接入的距離也因電源芯片及資料線的接入性能特點而所差距。在接入流程中會選用增強中繼的步驟對電磁波完成縮放，數量最多會加7個中繼，也只是說系統系統論上RS485的很大接入距離會能達到9.6公理。如若真還要長距離接入，會選用金屬為傳布推廣物料，接收兩端各加一些光電科技換算器，多模金屬的接入距離是5~10km/h，而選用單模金屬能夠能達到50km/h的傳布推廣距離。 At low speed and short distance, without the interference of occasions can use ordinary twisted pair. On the contrary, in the high speed and long distance transmission, you must use impedance matching (generally 120 Ohm) RS485 special cable (STP-120 omega (for RS485 & can) one pair 18 AWG), and under the severe jamming environment should also use type sheathed shielded twisted pair cable (ASTP-//www.anhdl.com120 omega (for RS485 & can) one pair 18 AWG). When using the RS485 interface, for specific transmission lines, from RS485 interface to load the baud rate of the data signal transmission allows maximum cable length and signal www.hejindianlan.com transmission is inversely proportional to, the length of the data is mainly by signal distortion and noise influence the effect. In theory, the communication speed in 100Kpbs and below, the longest transmission distance of RS485 up to 1200 meters, but the actual application of the transmission distance is also due to the transmission characteristics of the chip and the difference between the cable. In the transmission process can be used to increase the relay method to amplify the signal, up to eight relay, that is, the theory of the maximum transmission distance of RS485 can achieve the 9.6 axiom. If you really need to long distance transmission, using optical fiber as the transmission medium, the sending and receiving ends of the photoelectric converters and multimode fiber transmission distance is 5 to 10 km, and a single mode fiber (up to 50 km of the propagation distance.
