E1-4 Channel RS232/RS422/RS485 ConverterJHA-CE1D4/R4/Q4

Kakaretso

Sesebelisoa sena sa ho fetolela se thehiloe ho FPGA, se fana ka phetisetso ea 4Channel RS232/485/422 ho sebopeho sa E1. Sehlahisoa se senya likhohlano lipakeng tsa sebaka sa puisano sa serial interface le sekhahla sa puisano, ntle le moo, se ka rarolla tšitiso ea motlakase, tšitiso ea lesale la fatše le tšenyo ea lehalima. Sesebelisoa se ntlafatsa haholo ts'epo, ts'ireletso le lekunutu la puisano ea data. E sebelisoa haholo bakeng sa taolo e fapaneng ea indasteri, taolo ea ts'ebetso le linako tsa taolo ea sephethephethe, haholo bakeng sa Banka, le Matla le likarolo tse ling le litsamaiso tse nang le litlhoko tse ikhethang tsa tikoloho ea tšitiso ea motlakase. Seteishene sa RS232/RS485/RS422 se ka fetisetsa data ea serial e feto-fetohang ka mokhoa o tšoanang 0Kbps-57600Kbps sekhahla sa baud.
