Chii chinonzi rs-485 interface? Ndeapi maitiro ayo anoenzaniswa neRs-232-C interface? Nekuda kwekutaridzika kweRs-232-C interface standard, kunyanya zvikanganiso, zviri nyore kukuvadza chikamu cheTTL. (2) chiyero chekutapurirana chakaderera. Mune asynchronous kutapurirana, iyo baud rate ndeye 20kbps. . Uku kuzivikanwa kwekuvhurwa kunoitika kune zvakajairika mamiriro ekupindira, saka kuramba kukanganiswa kwekushomeka hakuna kusimba. (4) Iyo yekufambisa kureba ndeye mashoma. Iyo yakajairwa kukosha kwekutapurirana kwekutapurirana kusvika kure makumi mashanu emamita, asi inogona kungoshandiswa chete pamamita makumi mashanu. Tichifunga nezvekukanganisa kweRs-232-c, mamwe matsva emukati mwero wakabuda, uye Rs-485 ndeimwe yadzo. Iyo ine hunhu hunotevera: 1 Logic "0" inomiririrwa nemusiyano wepamhepo pakati pemitsetse miviri iri- (2-6) Vachiona 2. Iyo yepamusoro yepamusoro data yekufambisa yeRs-485 ndeye 10 MB PS3. Iyo Rs-485 interface ndeyekubatanidzwa kwemutyairi ane mwero uye utsinye anogamuchira, ayo anokwazisa anti-yakajairika yekuvhiringidza kugona, ndiko kuti, kugona kwekupindirana kwakanaka. 4 Mukuwedzera, maRs-232-C interface inongotenderwa kubatanidza imwe transceiver mubhazi, izvo, kuti, kuroora kamwe chete. Iyo Rs-485 interface inobvumira kubatana kweinosvika 128 kutapurirana mubhazi. Ndokunge, iyo kugona kweiyo yakawanda-station, kuitira kuti vashandisi vagone kumisikidza zvishandiso network nekushandisa yeRs-485 interface. RS-485 interface ndiyo yakasarudzika serial interface nekuda kwekunetseka kwayo kwekunetseka kwekunakisa, refu kuendesa kureba uye kuwanda-chiteshi kugona. Nekuti hafu-duplex network inoumbwa yeRs485 interfaffacs kazhinji inoda waya mbiri, Rs.485 inosangana neyekuvhara kwese kwekuvharirwa kaviri kutapurwa. Iyo 9-core plug sogket yeDB-9 inoshandiswa kuRs.485 Interface Connector neInternal Terminace Terminace Rs.85,
