E1-RS485 tụgharịrịr JHA-CE1D1

Nchịkọta

Nke a interface ntụgharị dabeere na FPGA, na-enye otu E1 interface na otu RS485 serial interface, 1Channel RS485 nnyefe site E1 interface. Ngwaahịa a na-agbaji site na esemokwu dị n'etiti anya nzikọrịta ozi serial interface ọdịnala na ọnụego nzikọrịta ozi, ewezuga, ọ nwekwara ike dozie nnyonye anya elektrọn, nnyonye anya mgbanaka ala na mmebi ọkụ. Ngwaọrụ na-eme ka ntụkwasị obi dịkwuo mma, nchekwa na nzuzo nke nzikọrịta data. A na-eji ya maka njikwa ụlọ ọrụ dị iche iche, njikwa usoro na oge njikwa okporo ụzọ, ọkachasị maka Bank, na ike na mpaghara ndị ọzọ na sistemụ nwere ihe pụrụ iche chọrọ maka gburugburu nnyonye anya electromagnetic. Ọnụego nzikọrịta ozi serial interface ruru 921.6KBPS.
