Protocol converter ka kakaretso e ka phethoa ka chip ea ASIC, e theko e tlase le e nyane ka boholo. E ka etsa phetoho e kopanetsoeng pakeng tsa Ethernet kapa V.35 data interface ea IEEE802.3 protocol le 2M interface ea G.703 protocol e tloaelehileng. E ka boela ea fetoloa pakeng tsa 232/485/422 serial port le E1, CAN interface le 2M interface, joale mesebetsi ea converter ea protocol ke efe? Taba ea pele, ts'ebetso ea relay: Kaha letšoao le fetisoa ka mohala, letšoao le tla fokotsoa ka mor'a sebaka se selelele. Ka hona, hoa hlokahala converter ea protocol ea marang-rang ho holisa le ho fetisa lets'oao. Etsa hore e fetisetsoe mochining o hole o shebiloeng. Ea bobeli, tumellano ea phetoho: Ho fana ka mohlala o bonolo ka ho fetisisa: ho marang-rang a marang-rang, li-protocol tse sebelisoang ka ho fetisisa ke RS232, RS485, CAN, USB, joalo-joalo Haeba PC ea hau e na le sekepe se le seng sa DB9 sa serial, 'me mochine o mong o hlokang ho buisana o sebelisa sebopeho sa USB. Joang ho e etsa? Tharollo e bonolo haholo, sebelisa feela USB-RS232 protocol converter. E tla ba linako tse peli tse fapaneng tsa protocol, maemo, joalo-joalo tse lokelang ho fapanyetsanoa. Puisano ea indasteri e hloka ho arolelana tlhahisoleseling le phapanyetsano ea data lipakeng tsa lisebelisoa tse ngata, 'me likou tse sebelisoang hangata tsa lisebelisoa tsa taolo ea indasteri li kenyelletsa RS-232, RS-485, CAN le marang-rang. Ho thata ho fapanyetsana litaba. Ka li-converter tsa li-multi-protocol, lisebelisoa tse nang le li-interfaces tse fapaneng li ka hokahanngoa ho lemoha tšebelisano pakeng tsa lisebelisoa. Ho ipapisitsoe le likou tse fapaneng tsa puisano le liprothokholo tse fapaneng, ho thehoa mefuta e mengata ea li-converter tsa protocol.
