Intengo Ephansi Kakhulu Rs422 Multiplexer - E1-RS485 Converter JHA-CE1D1 – JHA

E1-RS485 Iziguqulir JHA-CE1D1

Uhlolojikelele

Lesi siguquli esisebenzisanayo sisekelwe ku-FPGA, sinikeza isixhumi esibonakalayo esisodwa se-E1 kanye nesixhumi esibonakalayo esisodwa se-RS485, ukudluliswa kwe-1Channel RS485 ngesixhumi 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. Izinga lokuxhumana lokuxhumana kwe-serial lifika ku-921.6KBPS.

Isithombe Somkhiqizo

Uhlobo Oluncane

Izici

• Ngokusekelwe ku-IC self-copyright
• Ingathola ngokuzenzakalelayo futhi ilawule ukugeleza kwedatha ye-RS-485 ngaphandle kwamasiginali wokuxhawula ukuze ilawule ukugeleza kwedatha
• Iba nekhono lokubona ngokuzenzakalela izinga le-baud lesignali yembobo yomkhiqizo
• Hlola ngokuzenzakalela isizathu se-matt yedivayisi ukuthi idivayisi icishiwe, noma ulayini we-E1 uphukile. Bese ubonisa ku-LED
• Nikeza ama-impedances angu-2: 75 Ohm ukungalingani kanye nebhalansi engu-120 Ohm;
• Sekela Ukuphathwa Kwenethiwekhi ye-SNMP
• Isiteshi se-serial singadlulisela idatha ye-serial eguquguqukayo ngokuhambisana nesilinganiso se-baud esingu-300 Kbps-921.6Kbps
• Ukuphindaphindeka kwedatha ye-serial ku-E1 isekela imodi yokugxuma yekhodi ye-ITU-T R.111
• Isixhumi esibonakalayo se-serial port umbani-ukuvikelwa kufinyelele ku-IEC61000-4-5 (8/20μS) DM(Imodi Ehlukile): 6KV,Impedance (2 Ohm), CM(Imodi Ejwayelekile): 6KV, Impedance (2 Ohm) ejwayelekile
