Ukufika Okusha kwe-China Rs232 kuya ku-485 Converter - I-E1-2FE isikhombimsebenzisi Isiguquli JHA-CE1fF2p (i-lsolation ngokomzimba) - JHA

Isiguquli esibonakalayo se-E1-2FEI-JHA-CE1fF2p

(Ukukhululeka ngokomzimba)

Uhlolojikelele

Lesi siguquli esibonakalayo sisekelwe ku-FPGA. I-Multiplex 10/100Base-T Ethernet 2Channel interface kuya ku-E1 ukuze kunikezwe abasebenzisi ukufinyelela kwe-Ethernet ngenani lika-1984K. Isetshenziswa kakhulu eminyangweni yezezimali, yezokuphepha kanye nezokuphepha okudingeka ihlinzekwe ngamanethiwekhi amabili ahlukene, futhi kokubili kunethiwekhi ebonakalayo ingahlukaniswa ngokuphelele. Isibonelo, inethiwekhi yebhizinisi yesistimu yezezimali, inethiwekhi yehhovisi yangaphakathi kanye nenethiwekhi yebhizinisi ayikwazi ukuxhunywa ndawonye. Lesi multiplexer esibonakalayo singayixazulula le nkinga.

Isithombe Somkhiqizo

Uhlobo Oluncane

Izici

• Ngokusekelwe ku-IC ye-self-copyright
• I-E1 isekela noma iyiphi isethi yesikhathi, izinga lingu-64K-2048K
• Ingabona ukuqapha nokulawula imishini ekude, idatha yokuphatha ye-OAM ayizange ithathe isikhathi somsebenzisi futhi ilondoloze umkhawulokudonsa we-E1
• Yiba nomsebenzi we-E1 interface loop back check, gwema isiguquli siphahlazekile ngenxa ye-interface loop return; Yiba nesikhombi lapho idivayisi icishiwe noma

Umugqa we-E1 uphukile noma ulahlekelwe isignali;

• Ingabona ukudluliswa kwedatha ye-2Channel Ethernet ngamasekhethi angu-1 E1
• Ikheli le-Inter-set eliguqukayo le-Ethernet MAC (4,096) elinomsebenzi wokuhlunga uhlaka lwedatha yendawo
• Izinga le-2Channel Ethernet lingu-1984Kbps, setha izinga lesiteshi sokuqala, isilinganiso sesiteshi sesibili se-Ethernet isilinganiso sokunikezwa okuzenzakalelayo
• Idivayisi yasendaweni ingaphoqa ukuthi izinga ledivayisi elikude liyilandele
• Yiba nomsebenzi we-E1 interface loop back check, gwema isiguquli siphahlazekile ngenxa ye-interface loop return;
• Ingasetha umugqa we-E1 ukuthi ungathumeli isignali ye-LINK kusixhumi esibonakalayo se-Ethernet ngenkathi umugqa we-E1 uphukile;
• Isixhumi esibonakalayo se-Ethernet sisekela amafreyimu we-jumbo (2036 Bytes)
• Isixhumi esibonakalayo se-Ethernet sisekela i-10M/100M, Ukuxoxisana okuzenzakalelayo okuyingxenye/okugcwele okuyi-duplex kanye ne-AUTO-MDIX (umugqa oweqa futhi umugqa oqondile okwazi ukuzivumelanisa nezimo)
• Yiba nomsebenzi wokuzisetha kabusha we-Ethernet, okokusebenza ngeke kufe
• Nikeza izinhlobo zewashi ezi-2: Iwashi eliyinhloko le-E1 kanye newashi lomugqa we-E1;
• Iba ne-Loop Back Mode emithathu: i-E1 interface Loop Back (ANA),Isixhumi esibonakalayo se-Ethernet Loop Back(DIG),Yala isixhumi esibonakalayo se-Ethernet esikude Loop Back(REM)
• Nikeza ama-impedances angu-2: 75 Ohm ukungalingani kanye nebhalansi engu-120 Ohm;
• Qaphela ukuqapha izinga lokushisa lemishini ekude kanye ne-voltage emishinini yasendaweni;
• Uhlobo lwerakhi Ukusekela Ukuphathwa Kwenethiwekhi ye-SNMP;
