Nchịkọta

Nke a interface ntụgharị dabeere na FPGA, na-enye 31Channel RS232/485/422 nnyefe na 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. Ọwa RS232/RS485/RS422 nwere ike ibunye data serial asynchronously 0Kbps-14400bps baud ọnụego.
