USB 2.0 ho isa ho RS422 RS485 Adapter Cable
Tlhaloso ea Sehlahisoa
DT-5019 ke sesebelisoa sa bokahohleng sa USB 2.0 ho RS485/RS422, se se nang matla a tlatsetso, se lumellanang le litekanyetso tsa USB, RS422, RS485.E ka fetolela matshwao a USB hore e be matshwao a leka-lekaneng a RS422 kapa RS485.Mohala o mong le o mong o na le ts'ireletso ea surge, le ts'ireletso e fapaneng ea matla a ho phahama.Sebaka se senyenyane sa bokhoni se tiisa sebopeho sa RS422 / RS485 sa phetisetso ea lebelo le phahameng.RS422, RS485 hokela ka RJ45 le DB9 segokanyimmediamentsi sa sebolokigolo.
Transceiver e nang le zero e liehang ho feta ka hare, potoloho e ikhethang ea I/O e laola tsela ea phallo ea data ka bo eona, ntle le matšoao a ho ts'oarana ka letsoho (joalo ka RTS, DTR, joalo-joalo) le li-jumpers li sete li lemoha phetoho e felletseng ea duplex, half-duplex mode, plug le play. .Etsa bonnete ba hore sehlahisoa se lokisoa bakeng sa lisebelisoa tsohle tse teng tsa puisano le sebopeho sa hardware.
Li-converter tsa DT-5019 bakeng sa likhokahano tse tšepahalang tsa ntlha-to-point, ntlha-to-multi-point.E fana ka ntlha ea ho feta e 'ngoe le e' ngoe ea converter e lumella ho hokahanya lisebelisoa tse 32 RS422 kapa RS485, sekhahla sa data sa 300 ho isa ho 921600bps.Leseli la matla le phallo ea data le tla bontša phoso haeba ho na le ho senyeha ho itseng.Tšehetso ea puisano e na le USB ho RS422, USB ho RS485.
Likaroloana
1. Point-to-point / 4-line full-duplex.
2. Point-to-multi point / 4-line full-duplex.
3. Point-to-point / 2-line half-duplex.
4. Point-to-multi point / 2-line half-duplex.
Ha convertor e sebetsa ho full-duplex kapa half-duplex, e hloka ho eketsa khanyetso e ts'oanang ho qoba ho bonahatsa le tšitiso ea lets'oao.( 120Ω, 1/4W).
