Inkcazo ephezulu yeRs485 Isiguquli-Isiguquli esingamiselwanga E1-V.35 JHA-CE1V1 – JHA

Unframed E1-V.35 ConverterI-JHA-CE1V1

Isishwankathelo

Lo mguquleli we-interface ubonelela nge-E1 enye kunye ne-V.35 enye i-interface yokufezekisa i-interface ye-Unframed E1 yokudlulisa kwi-V.35 interface. Ireyithi yeshaneli yedatha yi-2.048Mbps. Isixhobo sinomsebenzi wokuvavanya i-loop ye-inter-set ukuququzelela ukuqaliswa kweprojekthi kunye nokugcinwa kwemihla ngemihla.

Ifoto yeMveliso

Uhlobo oluncinci

Iimbonakalo

• Ngokusekwe kwi-self-copyright IC
• I-E1 Interface Ukubonelela ngee-impedances ezi-2: 75 Ohm ukungalingani kunye ne-120 Ohm ibhalansi;
• Emva kovavanyo olungqongqo kunye nenkqubo yokuqinisekisa ebonakalayo, thobela ngokupheleleyo iprotocol ITU-T V.35, G.703, G.704
• Yiba neNdlela yokuNgena kweLoop emithathu: I-E1 interface yeLoop Back (ANA),V.35 ujongano lweLoop Back(DIG),Yalela i-remote
• V.35 ujongano lweLoop ngasemva(REM)
• Yiba ne-pseudo random code test function, lula ukuvulwa komgca, unokusetyenziswa njenge-2M BER Tester
• Ujongano lwe-V.35 luxhasa iplagi eshushu, ixhasa uqhagamshelo lwesixhobo se-DTE okanye se-DCE
• Ukubonelela ngeentlobo zewotshi ezi-3: iwotshi yangaphakathi, iwotshi yangaphandle, iwotshi yomgca we-E1;
• AC 220V, DC-48V, DC+24V, DC Power kunye nePolarity-Free
