Ikhwalithi enhle kakhulu ye-Rs485 kuya ku-Rs232 Isiguquli se-Serial - Isixhumi esibonakalayo Esizimele E1-FE+8RS232 Isiguquli se-JHA-CE1F1R8 – JHA

I-Frame interface E1-FE+8RS232 Converter I-JHA-CE1F1R8

Uhlolojikelele

Lesi siguquli sephrothokholi (isiguquli se-interface) sisebenzisa umklamo omkhulu we-FPGA, sihlinzeka ngohlaka lwe-E1 ozimele kanye nesixhumi esibonakalayo se-Ethernet kanye ne-8channel RS232/422/485, kungenzeka ukuzuza idatha ye-Ethernet engu-10/100Base-T phezu kokudluliswa kweziteshi ze-E1, kuphezulu kakhulu. ukusebenza, ukuzifundela ibhuloho le-Ethernet. Idivayisi isebenza njengesandiso samadivayisi e-Ethernet, ukusetshenziswa kwamanethiwekhi akhona (i-PDH / SDH / microwave, njll.) anikezwe amashaneli e-E1 ukuze axhume zombili iziphetho ze-Ethernet yezindleko eziphansi nezixhumi ezibonakalayo ze-serial. Amakhono emishini yokuhlola eyakhiwe nge-loop ukusiza ukuvulwa kanye nemisebenzi yokulungisa evamile.

Izici

• Ngokusekelwe ku-IC ye-self-copyright
• Ingabona ukuqapha nokulawula imishini ekude, idatha yokuphatha ye-OAM ayizange ithathe isikhathi somsebenzisi futhi ilondoloze umkhawulokudonsa we-E1
• I-E1 isekela noma iyiphi isethi yesikhathi, izinga lingu-64K-2048K
• Idivayisi yasendaweni ingaphoqa ukuthi izinga ledivayisi elikude liyilandele
• Yiba nesikhombi lapho idivayisi eyirimothi ivaliwe noma ulayini we-E1 uphukile noma ulahlekelwa isignali;
• Yiba nomsebenzi we-E1 interface loop back check, gwema isiguquli siphahlazekile ngenxa ye-interface loop return;
• I-interface ye-Ethernet isekela amafreyimu we-jumbo (2036 Bytes);
• Ikheli le-Inter-set eliguqukayo le-Ethernet MAC (4,096) elinomsebenzi wokuhlunga uhlaka lwedatha yendawo
• I-Ethernet interface isekela i-10M/100M, isigamu/egcwele i-duplex auto- Negotination, isekela i-VLAN
• Isixhumi esibonakalayo se-Ethernet sisekela i-AUTO-MDIX (umugqa onqanyuliwe kanye nomugqa oxhumeke oqondile ozivumelanisa nezimo);
• Yiba nomsebenzi wokuzisetha kabusha we-Ethernet, okokusebenza ngeke kufe
• Nikeza izinhlobo zewashi ezi-2: Iwashi eliyinhloko le-E1 kanye newashi lomugqa we-E1;
• Nikeza ama-impedances angu-2: 75 Ohm ukungalingani kanye nebhalansi engu-120 Ohm;
• Sekela Ukuphathwa Kwenethiwekhi ye-SNMP
• I-Serial Data Interface ingaba ngu-RS232/RS422/RS485/TTL ngokuzithandela
• Isiteshi se-serial singadlulisela idatha ye-serial eguquguqukayo ngokulinganayo 300 Kbps-19200Kbps izinga le-baud
• Ukuphindaphindeka kwedatha ye-serial ku-E1 isekela imodi yokugxuma yekhodi ye-ITU-T R.111
• Idatha ye-serial ye-RS232 yasendaweni ingayala i-RS232 serial data loop-back endaweni. Le loop-back eringini yangaphandle ye-RS232 data interface, ungahlola i-chip ye-RS232 ngaphandle kokulimala.
• I-serial port interface lightning-protection ifinyelelwe ku-IEC61000-4-5 (8/20μS) DM(Imodi Ehlukile): 6KV, Impedance (2 Ohm), CM(Imodi Ejwayelekile): 6KV, Impedance (2 Ohm) ejwayelekile
