Dzina lonse la RS-232 standard (protocol) ndi EIA-RS-232C standard, momwe EIA (Electronic Industry Association) imayimira American Electronic Industry Association, RS (muyezo wovomerezeka) imayimira mulingo wovomerezeka, 232 ndi nambala yozindikiritsa, ndipo C ikuyimira kukonzanso kwaposachedwa kwa RS232
Mtengo wa chizindikiro cha mawonekedwe a RS-232 ndi apamwamba, omwe ndi osavuta kuwononga chip cha mawonekedwe ozungulira.Mlingo wotumizira ndi wochepa, ndipo mtunda wotumizira ndi wocheperako, nthawi zambiri mkati mwa 20M.
RS-485 ili ndi mtunda wolumikizana wa mamita makumi masauzande a mita.Amagwiritsa ntchito kufalitsa koyenera komanso kulandila kosiyana.RS-485 ndi yabwino kwambiri yolumikizira mfundo zambiri.
RS422 mabasi, RS485 ndi RS422 mabwalo ali ofanana kwenikweni.Iwo amatumizidwa ndi kulandiridwa mu mode osiyana, ndipo safuna digito pansi waya.Kugwira ntchito kosiyana ndiko chifukwa chachikulu cha mtunda wautali wotumizira pamlingo womwewo, womwe ndi kusiyana kofunikira pakati pa RS232 ndi RS232, chifukwa RS232 ndizomwe zimapangidwira komanso zotulutsa, ndipo waya osachepera digito amafunikira kuti agwire ntchito ziwiri.Mzere wotumizira ndi mzere wolandira ndi mizere itatu (kutumiza kwa asynchronous), ndi mizere ina yolamulira ikhoza kuwonjezeredwa kuti amalize kuyanjanitsa ndi ntchito zina.
RS422 imatha kugwira ntchito mowirikiza popanda kukhudza wina ndi mnzake kudzera pamagulu awiri opotoka, pomwe RS485 imatha kugwira ntchito muwiri.Kutumiza ndi kulandira sikungathe kuchitidwa nthawi imodzi, koma kumangofunika awiriawiri opotoka.
RS422 ndi RS485 amatha kufalitsa mamita 1200 pa 19 kpbs.Zipangizo zitha kulumikizidwa pamzere watsopano wa transceiver.
63: Kodi ARM System ndi chiyani?Kwa mafakitale a LED, ntchito yake ndi yotani?
ARM (Advanced RISC Machines) ndi kampani yomwe imadziwika bwino pakupanga ndi kupanga tchipisi potengera ukadaulo wa RISC (Reduced Instruction Set Computer).Itha kuwonedwa ngati dzina la kampani, dzina lambiri la gulu la ma microprocessors, ndi dzina laukadaulo.Makina owongolera ma siginecha ndi makina opangira ma CPU omwe ali ndiukadaulo amatchedwa ARM system.Dongosolo lapadera la LED lopangidwa ndiukadaulo wa ARM limatha kuzindikira kuwongolera kosagwirizana.Njira zoyankhulirana zingaphatikizepo netiweki ya anzanu ndi anzawo, LAN, intaneti, ndi kulumikizana kwakanthawi.Ili ndi pafupifupi ma PC onse olumikizirana;
64: Kodi mawonekedwe a USB ndi chiyani?
Chidule cha Chingerezi cha USB ndi Universal Serial Bus, chomwe chimatanthawuza ku Chitchaina kuti "Universal Serial Bus", yomwe imadziwikanso kuti Universal Serial Interface.Imatha kuthandizira plugging yotentha ndipo imatha kulumikizana ndi zida zakunja za 127 PC;Pali mitundu iwiri ya mawonekedwe: USB1.0 ndi USB2.0
