Ukufika Okusha KwaseChina Ama-Rs232 Kuya Ku-485 Ukuguqulela - I-Serial kuya ku-E1 Guqula i-JHA-CE1Q1 – JHA

I-E1-RS422 ConverterI-JHA-CE1Q1

Uhlolojikelele

Lesi siguquli esibonakalayo sisekelwe ku-FPGA, sinikeza isixhumi esibonakalayo esisodwa se-E1 kanye nesixhumi esibonakalayo esisodwa se-RS422. 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 kwe-serial lifinyelela ku-512KBPS.

Isithombe Somkhiqizo

Uhlobo Oluncane

Izici

• Ngokusekelwe ku-IC ye-self-copyright
• 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-ukuvikela kufinyelele ku-IEC61000-4-5 (8/20μS) DM(Imodi Ehlukile): 6KV, Impedance (2 Ohm),CM(Imodi Ejwayelekile): 6KV, Impedance (2 Ohm) ejwayelekile
