Ukuchazwa okuphezulu kwe-Rs485 Converter - V Serial Interface Converter E1 Ukuze RS530 Uchungechunge JHA-CE1fR530 – JHA

Isiguquli esibonakalayo se-E1-RS530 esizimele I-JHA-CE1fR530

Uhlolojikelele

Lesi siguquli sephrothokholi sihlinzeka ngoxhumano lwe-E1 kanye nesixhumi esibonakalayo se-RS530 sinika amandla ukuguqulwa kwe-E1 kuya ku-RS530 phakathi kokuguqulwa kwesilinganiso se-E1 nemisebenzi yokukhipha i-slot. Imodi yozimele, umsebenzisi angakhipha izikhala zesikhathi ze-E1 n * 64K (n≤31) isiteshi sedatha; Imodi engenazimele, umsebenzisi angasebenzisa izinga lesiteshi sedatha elingu-2.048Mbps. Amakhono emishini yokuhlola eyakhiwe nge-loop ukusiza ukuvulwa kanye nemisebenzi yokulungisa evamile.

Izici

• Ngokusekelwe ku-IC ye-self-copyright
• Ungakwazi ukuhlukanisa lapho kuphelelwa umoya noma ikhefu lapho isignali ephakathi yokudlulisela i-E1 E1 ilahleka
• Ngenkathi isekela i-120Ω / ibhalansi eguquguqukayo kanye ne-75Ω / Imbalance impedance, asikho isidingo sokwenza izilungiselelo
• Uhlelo ngokuhlolwa okuqinile nokuqinisekisa okungokoqobo, okuhambisana ngokugcwele ne-EIA-530, ITU-T G.703, G.704 nezinye izincomo;
• Ihlinzeka ngemisebenzi emithathu ye-loopback: I-E1 loopback yendawo (ANA), i-RS530 loopback (DIG), i-oda i-RS530 loopback (REM);
• Umsebenzi wokuhlola ikhodi okungahleliwe, okungukuthi ukwenza lula ukuvulwa komugqa, lapho umuntu engeza ne-2M BERT
• I-DTE noma i-DCE ukusekelwa kanye nokuxhumana; I-RS530 interface isekela ukushintshashintsha okushisayo
• Umsebenzi wewashi le-RS530 usekela iwashi langaphakathi, iwashi langaphandle kanye newashi lomugqa;
• Uma uthanda i-AC 220V, DC -48V, DC + 24V, ugesi we-DC awekho amaphuzu amahle noma angalungile
