faahfaahinta badeecada
RS-485 waa halbeeg koronto oo keliya. Si ka duwan heerarka is-dhexgalka oo dhammaystiran, kuwaas oo qeexaya qeexitaannada shaqada, farsamada, iyo korontada, RS-485 waxay qeexaysaa oo keliya astaamaha korantada ee kontaroolayaasha iyo qaataha loo isticmaali karo in lagu hirgeliyo xariiq gudbin oo dheellitiran oo dhinacyo badan leh. Si kastaba ha ahaatee, heerkan waxaa loogu talagalay in lagu tixraaco heerarka heerka sare, sida DL/T645, tusaale ahaan, kaas oo qeexaya hab-maamuuska isgaarsiinta ee mitirrada tamarta elektaroonigga ah ee Shiinaha, isagoo qeexaya RS-485 heerka lakabka jireed. Astaamaha: 1. U adkaysta kulaylka iyo dab-damiska. 2. Waxqabadka dahaarka oo aad u fiican iyo xasilloonida kiimikada. 3. Waxqabadka gudbinta oo aad u fiican sababtoo ah isticmaalka polyethylene tayo sare leh oo loogu talagalay ilaalinta fiilada tidcan. 4. Iska caabin wax ku ool ah oo ku wajahan faragelinta elektromagnetic-ka sababtoo ah isticmaalka nooc cusub oo bir ah aluminium ah iyo gaashaanka shabagga naxaasta ee laba lakab leh. Codsiyada: Calaamadaha RS-485 waxaa loo isticmaalaa nidaamyo badan oo kombiyuutar iyo otomaatig ah. Nidaamka kombiyuutarka, SCSI-2 iyo SCSI-3 waxay u isticmaali karaan qeexitaankan si ay u hirgeliyaan lakabka jireed ee gudbinta xogta ee u dhexeeya koontaroolaha iyo darawalka diskka. RS-485 waxaa loo isticmaalaa isgaarsiinta xogta xawaaraha hoose ee basaska baabuurta rakaabka ee qolalka diyaaradaha ganacsiga. Waxay u baahan tahay fiilo yar waxayna wadaagi kartaa fiilo kuraas badan, taasoo yareyneysa miisaanka.
