新產品的介紹 RS-485通信纜線在般場景所運用雙絞合就也會，但在條件相對較高的學習壞境下也會所運用帶屏弊層的雙絞纜線。在的使用RS485通信時，在相應的發送火車線路，主機主設備（召測主設備）到儀表板的485口間的纜線粗度與數劇表現發送的波特率相差懸殊；一個粗度注意受表現的偏色并且壞境噪聲的會后果所會后果。理論研究上RS485的發送遠距里能做到1200米，但預期應用領域中發送遠距里要超過1200米，具體化粗度受附進的學習壞境會后果。 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 在中速、短距、無影向的情況是行選擇平常的雙銅絞合線，不然的話，在極速、短線互傳時，則一定選擇阻抗適合適合(普通為120Ω)的RS485上用纜線線(STP-120Ω(for RS485 & CAN) one pair 18 AWG)，而在影向惡略的場景下還應選擇鎧裝型雙絞閉屏纜線線(ASTP-120Ω(for RS485 & CAN) one pair 18 AWG)。在操作RS485主板接口方式時，就不同的互傳高壓線路，從RS485主板接口方式到阻抗其動態數據文件數據文件信息互傳所準許的明顯纜線線粗度與數據文件信息互傳的波特率反比，這一粗度動態數據文件主要是受數據文件信息模糊及噪音等影向所影向。原理與實踐上，通信網絡波特率在100Kpbs及一下時，RS485的最久互傳距能達1200米，但在現實的利用中互傳的距也因處理芯片及纜線線的互傳優點而所不一致性。在互傳過程中中是行選擇添加中繼的方法步驟對數據文件信息來擴大，最高是行加五個中繼，也也是說原理與實踐上RS485的明顯互傳距是行超過9.6公理。如真想要長距互傳，是行選擇網絡網絡電信光纖為校園營銷物料，收發的時候兩端各加某個光電材料變換器，多模網絡網絡電信光纖的互傳距是5~10多公里數，而選擇單模網絡網絡電信光纖能達50多公里數的校園營銷距。 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.
