Imikhiqizo
Intengo ephansi kakhulu yekhebula le-Fiber Optic - i-RS485 esontekile enezisekelo ezimbili, izisekelo ezintathu, izinhliziyo ezine, 20AWG 22AWG 18AWG - AIXTON
Siyajabula ukuphendula noma yimiphi imibuzo, sicela usithumelele imibuzo yakho kanye nama-oda akho.
imininingwane yomkhiqizo
I-RS-485 iyindinganiso kagesi kuphela. Ngokungafani nezindinganiso ezibanzi zesixhumi esibonakalayo, ezichaza imininingwane yokusebenza, yemishini, kanye neyegesi, i-RS-485 ichaza kuphela izici zikagesi zabalawuli nabamukeli ezingasetshenziswa ukusebenzisa umugqa wokudlulisa olinganiselayo wamaphuzu amaningi. Nokho, le ndinganiso ihloselwe ukubhekiswa yizindinganiso zezinga eliphezulu, njenge-DL/T645, isibonelo, echaza inqubo yokuxhumana yamamitha wamandla kagesi eShayina, icacisa i-RS-485 njengendinganiso yengqimba ebonakalayo. Izici: 1. Ayimelani nokushisa futhi ayishisi ilangabi. 2. Ukusebenza kahle kokushisa kanye nokuqina kwamakhemikhali. 3. Ukusebenza kahle kokudlulisa ngenxa yokusebenzisa i-polyethylene esezingeni eliphezulu yokuvikela ikhebula elilukiwe. 4. Ukumelana okuphumelelayo nokuphazamiseka kwe-electromagnetic ngenxa yokusebenzisa uhlobo olusha lwe-aluminium foil kanye nokuvikela i-copper mesh okulukiwe okuphindwe kabili. Izicelo: Amasignali e-RS-485 asetshenziswa ezinhlelweni eziningi zekhompyutha kanye ne-automation. Kuhlelo lwekhompyutha, i-SCSI-2 kanye ne-SCSI-3 zingasebenzisa le ncazelo ukuze zisebenzise ungqimba olubonakalayo lokudlulisa idatha phakathi kwesilawuli kanye ne-disk drive. I-RS-485 isetshenziselwa ukuxhumana kwedatha ngesivinini esiphansi emabhasini ezimoto zabagibeli ezindlini zezindiza zezentengiselwano. Idinga izintambo ezincane futhi ingabelana ngezintambo phakathi kwezihlalo eziningi, okunciphisa isisindo.
