I-USB 2.0 ukuya ku-RS422 RS485 Adapter Cable
Incazelo Yomkhiqizo
I-DT-5019 isiguquli sendawo yonke se-USB 2.0 kuya ku-RS485/RS422, engenawo amandla angeziwe, ahambisana ne-USB, RS422, RS485 amazinga.Ingakwazi ukuguqula amasignali e-USB abe umehluko olinganiselayo we-RS422 noma amasiginali we-RS485.Ulayini ngamunye unokuvikelwa kokukhuphuka, kanye nokuvikela okuhlukahlukene kwamandla kagesi.Ibanga elincane le-capacitance liqinisekisa isixhumi esibonakalayo se-RS422 / RS485 sokudluliswa kwesivinini esikhulu.I-RS422, RS485 ixhumeka ngesixhumi esibonakalayo se-RJ45 ne-DB9.
Isiguquli esine-othomathikhi ye-othomathikhi engu-zero, isekethe ye-I/O eyingqayizivele ilawula ngokuzenzakalelayo ukugeleza kwedatha, ngaphandle kwezimpawu zokuxhawula izandla (njenge-RTS, i-DTR, njll.) kanye nesethi yama-jumpers aqaphela ukuguqulwa kwemodi ye-duplex egcwele, i-half-duplex, ipulaki nokudlala. .Qinisekisa ukulungiswa komkhiqizo kwayo yonke isofthiwe yokuxhumana ekhona kanye nesixhumi esibonakalayo sehadiwe.
Iziguquli ze-DT-5019 zokuxhumana okuthembekile kwe-point-to-point, khomba-ku-multi-point.Ihlinzeka ngephoyinti kokuningi isiguquli ngasinye sivumela ukuxhuma amadivayisi angu-32 RS422 noma RS485, izinga ledatha lika-300 kuya ku-921600bps.Isibani sesikhombi samandla nokugeleza kwedatha sizobonisa iphutha uma kukhona ukwehlukana.Ukusekelwa kokuxhumana kune-USB kuya ku-RS422, i-USB kuya ku-RS485.
Izici
1. Iphoyinti-kuya-iphuzu / imigqa emi-4 egcwele-duplex.
2. Iphoyinti lokukhomba-kuya-kuningi / imigqa emi-4 egcwele-duplex.
3. Iphoyinti-kuya-iphuzu / imigqa emi-2 ephindwe kabili.
4. Iphoyinti lokukhomba-kuya-kuningi / imigqa emi-2 ephindwe kabili.
Uma isiguquli sisebenza ku-full-duplex noma ku-half-duplex, sidinga ukungeza ukumelana okufanayo ukuze kugwenywe ukubonisa kanye nokuphazamiseka kwesignali.( 120Ω, 1/4W).
