2019 Ikhwalithi ephezulu Rs232 Kuya ku-Rs485 - E1-4 Isiteshi RS232/RS422/RS485 Converter JHA-CE1D4/R4/Q4 – JHA

I-E1-4 Channel RS232/RS422/RS485 ConverterJHA-CE1D4/R4/Q4

Uhlolojikelele

Lesi siguquli esibonakalayo sisekelwe ku-FPGA, sihlinzeka nge-4Channel RS232/485/422 ngokudluliswa kwesixhumi esibonakalayo se-E1. Umkhiqizo unqamula ukungqubuzana phakathi kwebanga lokuxhumana le-serial interface yendabuko kanye nezinga lokuxhumana, ngaphandle kwalokho, futhi ungaxazulula ukuphazamiseka kukazibuthe, ukuphazamiseka kwendandatho yaphansi kanye nokulimala kombani. Idivayisi ithuthukisa kakhulu ukuthembeka, ukuphepha kanye nokugcinwa kuyimfihlo kokuxhumana kwedatha. Isetshenziswa kabanzi ekulawuleni izimboni ezahlukahlukene, ukulawulwa kwenqubo kanye nezikhathi zokulawulwa kwethrafikhi, ikakhulukazi eBhange, namandla kanye neminye imikhakha nezinhlelo ezinezidingo ezikhethekile zokuphazanyiswa kwemvelo kazibuthe. Isiteshi se-RS232/RS485/RS422 singadlulisela idatha ye-serial eguquguqukayo ngokuhambisana nesilinganiso se-baud esingu-0Kbps-57600Kbps.
