Isiguquli sephrothokholi ngokuvamile singaqedwa nge-chip ye-ASIC, enezindleko eziphansi nosayizi omncane.Ingenza ukuguqulwa okufanayo phakathi kwe-Ethernet noma i-V.35 idatha interface yephrothokholi ye-IEEE802.3 kanye nesixhumi esibonakalayo esingu-2M sephrothokholi evamile ye-G.703.Ingabuye iguqulwe phakathi kwe-232/485/422 port ye-serial kanye ne-E1, i-CAN interface kanye ne-interface ye-2M, ngakho-ke iyini imisebenzi yesiguquli sephrothokholi? Okokuqala, umsebenzi wokudlulisa: Njengoba isignali idluliselwa ngocingo, isignali izoncishiswa ngemva kwebanga elide.Ngakho-ke, isiguquli sephrothokholi yenethiwekhi siyadingeka ukuze kukhuliswe futhi kudluliselwe isignali.Kwenze kudluliselwe emshinini oqondiswe kude. Okwesibili, isivumelwano sokuguqulwa: Ukunikeza isibonelo esilula: kunethiwekhi yochungechunge, izivumelwano ezisetshenziswa kakhulu yi-RS232, RS485, CAN, USB, njll. Uma i-PC yakho inembobo yomkhiqizo eyodwa ye-DB9, kanti omunye umshini odinga ukuxhumana usebenzisa isixhumi esibonakalayo se-USB.Kwenziwa kanjani?Isixazululo silula kakhulu, vele usebenzise i-USB-RS232 protocol converter.Kuzoba izikhathi ezimbili ezihlukene zephrothokholi, amaleveli, njll. okumele kushintshwe. Ukuxhumana kwezimboni kudinga ukwabelana ngolwazi nokushintshisana ngedatha phakathi kwamadivayisi amaningi, futhi izimbobo zokuxhumana ezivame ukusetshenziswa zemishini yokulawula yezimboni zifaka i-RS-232, RS-485, CAN nenethiwekhi.Kunzima ukushintshanisa ulwazi.Ngeziguquli ezinamaphrothokholi amaningi, amadivaysi anokuxhumana okuhlukile angaxhunywa kunethiwekhi ukuze abone ukusebenzisana phakathi kwamadivayisi.Ngokusekelwe ezinhlobonhlobo zamachweba okuxhumana kanye namaphrothokholi ahlukahlukene, kwakhiwa izinhlobo eziningi zokuguqula amaphrothokholi.
