2019 lag luam wholesale nqe Rs232 rau Ethernet - Co-Directional 64K-RS232/422/485 Converter JHA-CE1tD1/R1/Q1 - JHA

Co-Directional 64K-RS232/422/485 Converter JHA-CE1tD1/R1/Q1

Txheej txheem cej luam  

Lub G.703 (Co-Directional G.703) interface faib 64Kbps voj voog mus rau 4 chav nyob ib ntus, nws siv "0101" sawv cev "0", "1100" sawv cev "1". Los ntawm alternating transformation polarity ntawm lub block uas nyob ib sab, binary signals hloov peb theem teeb liab. Hauv txhua pab pawg thib 8 tau rhuav tshem thaiv kev hloov pauv ntawm polarity, yog li xa 8KHz lub sijhawm teeb tsa. Los ntawm cov coding saum toj no, G.703 co-directional 64Kbps teeb liab tuaj yeem ua tiav lub sijhawm xa cov teeb liab ntawm 64KHz thiab 8KHz thiab 64KHz thiab cov ntaub ntawv teeb liab ntawm 64Kbit / s nyob rau tib txoj kev nrog ib khub sib npaug kab.
64k-RS232/422/485 interface converter muab ITU-T co-64K G.703 txheem E1 interface thiab txheem RS232/422/485 hloov dua siab tshiab interface ntawm lub cev txheej. Network muab kev sib txuas lus ruaj ntseg ntawm cov khoom siv sib txawv interfaces, kev sib txuas seamless. Tsim nyog rau cov khoom siv kis tau tus mob E1 channel qhov chaw muaj, thiab cov khoom siv xav tau los hloov cov ntaub ntawv thiab tsuas yog RS232 / 422 / 485 qhov hluav taws xob lub sijhawm.
