Umguquleli weprotocol unokugqitywa ngokubanzi nge-chip ye-ASIC, ephantsi kweendleko kunye nobukhulu obuncinci. Iyakwazi ukwenza ukuguqulwa okulinganayo phakathi kwe-Ethernet okanye i-V.35 i-interface yedatha ye-IEEE802.3 protocol kunye ne-interface ye-2M ye-standard G.703 protocol. Iyakwazi ukuguqulwa phakathi kwe-232/485/422 i-serial port kunye ne-E1, i-CAN interface kunye ne-interface ye-2M, ngoko yintoni imisebenzi yokuguqula iprotocol? Okokuqala, umsebenzi wokudlulisa: Ekubeni isibonakaliso sithunyelwa kwi-wire, uphawu luya kuthotywa emva komgama omde. Ke ngoko, isiguquli seprotocol yenethiwekhi iyafuneka ukuze kwandiswe kwaye kudluliselwe umqondiso. Yenze ukuba isasaze kumatshini ekujoliswe kuwo. Okwesibini, isivumelwano sokuguqulwa: Ukunika umzekelo olula: kuthungelwano lwe-serial, iiprothokholi ezisetyenziswa ngokuqhelekileyo ziyi-RS232, RS485, CAN, USB, njl. Ukuba i-PC yakho ine-port ye-serial ye-DB9 enye kuphela, kunye nomnye umatshini ofuna ukunxibelelana usebenzisa i-interface ye-USB. Ukwenza njani? Isisombululo silula kakhulu, sebenzisa nje i-USB-RS232 protocol converter. Kuya kuba ngamaxesha amabini ahlukeneyo eprotocol, amanqanaba, njl. Unxibelelwano lwezoShishino lufuna ukwabelana ngolwazi kunye notshintshiselwano lwedatha phakathi kwezixhobo ezininzi, kunye namazibuko onxibelelwano aqhelekileyo asetyenziswa kwizixhobo zolawulo lwamashishini abandakanya iRS-232, RS-485, CAN kunye nenethiwekhi. Kunzima ukutshintshiselana ngolwazi. Ngokusebenzisa ii-multi-protocol converters, izixhobo ezinonxibelelwano oluhlukeneyo zinokuthungelwa kuthungelwano ukuze ziqonde ukusebenzisana phakathi kwezixhobo. Ngokusekwe kwiintlobo ngeentlobo zezibuko zonxibelelwano kunye neeprothokholi ezahlukeneyo, iintlobo ngeentlobo zabaguquli beeprotocol ziyenziwa.
