RS-485通信技術的設備低壓低壓纜線在一半地方用到雙銅絞合線就是會，但在耍求很高的室內周圍環境下是會用到帶關閉層的雙絞低壓低壓纜線。在運行RS485通信技術的設備時，相對于指定的傳遞配電線路，主機箱（召測的設備）到儀表板的485口間的低壓低壓纜線長寬高與數據源數字信號燈傳遞的波特率負相關；這長寬高最主要受數字信號燈的偏色并且躁聲的應響所應響。理論與實踐上RS485的傳遞路程能可達1200米，但實際上APP中傳遞路程要小于等于1200米，實際上長寬高受較近的室內周圍環境應響。
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
在低速度、短范圍、無擾亂的情況可能選取普通型的雙銅絞合線，反過來，在飛速、短線輸送時，則不得不選取電阻值配備(基本為120Ω)的RS485專業電覽(STP-120Ω(for RS485 & CAN) one pair 18 AWG)，而在擾亂寒冷的區域環境下還應選取鎧裝型雙絞禁掉電覽(ASTP-120Ω(for RS485 & CAN) one pair 18 AWG)。在食用RS485模塊時，對待獨特的輸送電覽線，從RS485模塊到根據其信息預警輸送所支持的大電覽時間與預警輸送的波特率關系不大，你這個時間信息重點是受預警偏色及嗓聲等直接影響到所直接影響到。系統論上，溝通傳送速度在100Kpbs及以內時，RS485的比較大輸送范圍相當于1200米，但在實際情況選用中輸送的范圍也因集成電路芯片及電覽的輸送性狀而所差別的。在輸送時候中可能選取曾加中繼的的方法對預警開始拖動，最小可能加九個中繼，也也就算系統論上RS485的大輸送范圍可能達到9.6公理。一旦真必須 長范圍輸送，可能選取金屬為宣傳推廣有機溶劑，出入庫兩端各加同一個光電科技轉換成器，多模金屬的輸送范圍是5~10Km，而選取單模金屬相當于50Km的宣傳推廣范圍。
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.
