RS-485 ifite intera y'itumanaho ya metero icumi kugeza kuri metero ibihumbi.Ikoresha ihererekanyabubasha hamwe no kwakira bitandukanye.RS-485 iroroshye cyane guhuza ingingo nyinshi.
Bisi ya RS422, RS485 na RS422 umuzenguruko ni bimwe muburyo bumwe.Boherejwe kandi bakiriwe muburyo butandukanye, kandi ntibakeneye insinga zubutaka.Igikorwa gitandukanye nimpamvu yibanze yintera ndende yoherejwe ku kigero kimwe, niryo tandukaniro ryibanze hagati ya RS232 na RS232, kubera ko RS232 ari iyinjiza rimwe kandi isohoka, kandi byibuze insinga ya digitale irakenewe kugirango duplex ikore.Kohereza umurongo no kwakira umurongo ni imirongo itatu (ihererekanyabubasha), indi mirongo igenzura irashobora kongerwaho kugirango ihuze neza hamwe nibindi bikorwa.
RS422 irashobora gukora muri duplex yuzuye itagize ingaruka kuri mugenzi wawe binyuze mubice bibiri byerekeranye, mugihe RS485 ishobora gukora muri kimwe cya kabiri.Kohereza no kwakira ntibishobora gukorwa icyarimwe, ariko bikenera gusa bibiri byombi bigoretse.
RS422 na RS485 birashobora kohereza metero 1200 kuri 19 kpbs.Ibikoresho birashobora guhuzwa kumurongo mushya wa transceiver.
63: Sisitemu ya ARM ni iki?Ku nganda LED, ikoresha iki?
ARM (Advanced RISC Machines) nisosiyete kabuhariwe mu gushushanya no guteza imbere chip zishingiye ku ikoranabuhanga rya RISC (Reduced Instruction Set Computer).Irashobora gufatwa nkizina ryisosiyete, izina rusange ryicyiciro cya microprocessor, nizina ryikoranabuhanga.Sisitemu yo kugenzura no gutunganya sisitemu ishingiye kuri CPU hamwe n'ikoranabuhanga yitwa sisitemu ya ARM.Sisitemu idasanzwe yo kugenzura yakozwe na tekinoroji ya ARM irashobora kumenya kugenzura idahwitse.Uburyo bwitumanaho bushobora kubamo urungano rwurungano, LAN, interineti, hamwe nuruhererekane.Irimo hafi ya PC yose;
64: Interineti ya USB ni iki?
Icyongereza mu magambo ahinnye ya USB ni Universal Serial Bus, isobanura mu Gishinwa nka “Universal Serial Bus”, izwi kandi ku izina rya Universal Serial Interface.Irashobora gushyigikira gucomeka kandi irashobora guhuza ibikoresho bigera kuri 127 PC byo hanze;Hano hari amahame abiri yimbere: USB1.0 na USB2.0
