2019 Umgangatho ophezulu we-Rs232 ukuya kwi-Rs485 - E1-4 Ijelo RS232/RS422/RS485 Converter JHA-CE1D4/R4/Q4 – JHA

E1-4 Ijelo le-RS232/RS422/RS485 ConverterJHA-CE1D4/R4/Q4

Isishwankathelo

Lo mguquli we-interface usekelwe kwi-FPGA, ukubonelela nge-4Channel RS232/485/422 ukuhanjiswa kwi-E1 interface. Imveliso iqhekeza ukuchasana phakathi komgama wonxibelelwano lwe-serial yesiqhelo kunye nesantya sonxibelelwano, ngaphandle koko, inokusombulula ukuphazamiseka kwe-electromagnetic, ukuphazamiseka kweringi yomhlaba kunye nomonakalo wombane. Isixhobo siphucula kakhulu ukuthembeka, ukhuseleko kunye nemfihlo yonxibelelwano lwedatha. Isetyenziswa ngokubanzi kulawulo lwemizi-mveliso eyahlukeneyo, ulawulo lwenkqubo kunye nezihlandlo zolawulo lwezithuthi, ngakumbi kwiBhanki, kunye naMandla kunye namanye amacandelo kunye neenkqubo ezineemfuno ezizodwa zokuphazamiseka kombane wombane. I-RS232/RS485/RS422 ishaneli inokuhambisa idatha yeserial eguquguqukayo ngokulinganayo 0Kbps-57600Kbps izinga le-baud.
