Kakaretso

Sesebelisoa sena sa ho fetolela se thehiloe ho FPGA, se fana ka phetiso ea 1Channel 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 ea liindasteri tse fapaneng, 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 lumellanang le sekhahla sa baud sa 512kbps.

Likaroloana

• E ipapisitse le IC ea boinotšing
• Support 3 interfaces RS232, RS422, RS485, u ka sebelisa e le 'ngoe feela, u ke ke ua sebelisa li-interfaces tse tharo ka nako e le' ngoe.
• E khona ho bona le ho laola phallo ea data ea RS-485 ntle le matšoao a ho ts'oarana ka letsoho ho laola tsela ea phallo ea data
• Eba le bokhoni ba ho lemoha ka bo eona sekhahla sa baud sa lets'oao la serial port
• Lekola lebaka la matt ea sesebelisoa ke hore sesebelisoa se tima, kapa mohala oa E1 o robehile. Ebe u bontša ka LED
