iinkcukacha zemveliso
I-RS-485 ngumgangatho osetyenziswa ngombane kuphela. Ngokungafaniyo nemigangatho ebanzi yojongano, echaza iinkcukacha ezisebenzayo, ezoomatshini, nezombane, i-RS-485 ichaza kuphela iimpawu zombane zabalawuli kunye nabamkeli ezinokusetyenziselwa ukuphumeza umgca wokudlulisela olinganiselayo we-multipoint. Nangona kunjalo, lo mgangatho ujoliswe ekubhekiselweni kwimigangatho ephezulu, efana ne-DL/T645, umzekelo, echaza iprotokholi yonxibelelwano lweemitha zamandla e-elektroniki eTshayina, ichaza i-RS-485 njengomgangatho womaleko obonakalayo. Iimpawu: 1. Ayinabushushu kwaye ayitshisi ilangabi. 2. Ukusebenza kakuhle kobushushu kunye nokuzinza kweekhemikhali. 3. Ukusebenza kakuhle kokudlulisela ngenxa yokusetyenziswa kwe-polyethylene ekumgangatho ophezulu yokukhusela intambo eboyiweyo. 4. Ukuxhathisa ngempumelelo ukuphazamiseka kwe-electromagnetic ngenxa yokusetyenziswa kohlobo olutsha lwe-aluminium foil kunye nokukhusela i-copper mesh eboyiweyo ephindwe kabini. Izicelo: Izibonakaliso ze-RS-485 zisetyenziswa kuluhlu olubanzi lweenkqubo zekhompyutha kunye ne-automation. Kwinkqubo yekhompyutha, i-SCSI-2 kunye ne-SCSI-3 zinokusebenzisa olu lwazi ukuphumeza umaleko obonakalayo wokudlulisela idatha phakathi komlawuli kunye ne-disk drive. I-RS-485 isetyenziselwa unxibelelwano lwedatha olukhawulezayo kwiibhasi zezithuthi zabakhweli kwiikhabhini zeenqwelo-moya zorhwebo. Ifuna iintambo ezincinci kwaye inokwabelana ngeentambo phakathi kwezihlalo ezininzi, nto leyo enciphisa ubunzima.
