Kusintha kwa protocol kumatha kumalizidwa ndi chipangizo cha ASIC, chomwe ndi chotsika mtengo komanso chaching'ono.Ikhoza kuchita kutembenuka kwapakati pakati pa Efaneti kapena V.35 deta mawonekedwe a protocol IEEE802.3 ndi 2M mawonekedwe a muyezo G.703 protocol.Itha kusinthidwanso pakati pa doko la 232/485/422 ndi E1, CAN mawonekedwe ndi mawonekedwe a 2M, ndiye ntchito yosinthira protocol ndi yotani? Choyamba, ntchito ya relay: Popeza chizindikirocho chimaperekedwa pawaya, chizindikirocho chidzachepetsedwa pambuyo pa mtunda wautali.Chifukwa chake, chosinthira cha protocol cha netiweki chikufunika kuti chikulitse ndi kutumiza chizindikirocho.Pangani kuti iperekedwe ku makina akutali. Chachiwiri, mgwirizano wotembenuka: Kuti tipereke chitsanzo chophweka: mumsewu wambiri, ma protocol omwe amagwiritsidwa ntchito kwambiri ndi RS232, RS485, CAN, USB, ndi zina zotero. Ngati PC yanu ili ndi doko limodzi lokha la DB9, ndipo makina ena omwe amafunikira kulankhulana amagwiritsa ntchito mawonekedwe a USB.Kodi kuchita izo?Yankho lake ndi losavuta, ingogwiritsani ntchito USB-RS232 protocol converter.Zidzakhala ziwiri zosiyana nthawi ya protocol, milingo, ndi zina zambiri kuti zisinthidwe. Kuyankhulana kwa mafakitale kumafuna kugawana zidziwitso ndi kusinthana kwa data pakati pa zida zingapo, ndipo madoko olumikizirana omwe amagwiritsidwa ntchito kwambiri pazida zowongolera mafakitale ndi monga RS-232, RS-485, CAN ndi netiweki.Ndizovuta kugawana zambiri.Kupyolera mu ma converter amitundu yambiri, zida zomwe zili ndi mawonekedwe osiyanasiyana zimatha kulumikizidwa kuti zizindikire kugwirizana pakati pa zida.Kutengera ma doko osiyanasiyana olumikizirana komanso ma protocol osiyanasiyana, osintha ma protocol osiyanasiyana amapangidwa.
