Elona xabiso liphantsi leFiber Optic Cable-Rs485 ejijekileyo 2 core 3 core 4 cores 20AWG 22AWG 18AWG - AIXTON

Iinkcukacha RS-485 ngumgangatho wombane kuphela. Ngokungafaniyo nemigangatho ye-interface epheleleyo, echaza i-functional, mechanical, kunye neenkcukacha zombane, i-RS-485 ichaza kuphela iimpawu zombane zabaqhubi kunye nabamkeli abangasetyenziselwa ukuphumeza umgca we-multidrop transmission line. Lo mgangatho, nangona kunjalo, ujoliswe ukuba ubhekiselwe kwimigangatho yezinga eliphezulu, njenge-DL / T645, umzekelo, echaza iprotocol yonxibelelwano. kwiimitha zamandla e-elektroniki eTshayina, ichaza iRS-485 njengomgangatho womgangatho womzimba. Iimpawu 1.Ukumelana nobushushu, ukunqandwa komlilo 2.ukusebenza kakuhle kwe-insulation, ukusebenza kweekhemikhali ezizinzile 3.ukusebenza okugqwesileyo kokuhanjiswa ngenxa yokusetyenziswa kwe-polyethylene ephezulu yokukhusela intambo ephothiweyo 4.Ukumelana okusebenzayo nokuphazamiseka kwe-electromagnetic ngenxa yokusetyenziswa Yenziwe uhlobo olutsha lwe Ifoyile ye-aluminiyam, i-double-layer braided copper mesh shielding. Izicelo Izibonakaliso ze-RS-485 zisetyenziswa kuluhlu olubanzi lweekhompyuter kunye neenkqubo ezizenzekelayo. Kwinkqubo yekhompyuter, i-SCSI-2 kunye ne-SCSI-3 inokusebenzisa le nkcazo ukuphumeza umaleko womzimba wokuhanjiswa kwedatha phakathi komlawuli kunye nediski drive. I-RS-485 isetyenziselwa unxibelelwano lwedatha yesantya esisezantsi kwiibhasi zezithuthi zekhabhinethi yeenqwelomoya. Ifuna i-wiring encinci kwaye inokwabelana nge-wiring phakathi kwezihlalo ezininzi, ukunciphisa ubunzima.
