Tafura A-1: ​​Kubatana Pakati Pemaviri RS422 Devices
Kushaikwa kwechitatu kweRS232 ndeyekuti michina inodarika miviri haigone kugovera tambo imwechete. Izvi ndezvechokwadi zvakare kune RS422 asi RS485 inopa ese mabhenefiti eRS422 plus inobvumira anosvika makumi matatu nemaviri emidziyo kugovera maviri akafanana akamonyoroka. Kunze kwezviri pamusoro apa ndezvokuti akawanda maRS32 maturusi anogona kugovera tambo imwe chete kana imwe chete ichataura uye vamwe vachigara vachigamuchira.

Yakaenzana Yakasiyana Zviratidzo

Chikonzero icho RS422 uye RS485 zvishandiso zvinogona kutyaira mitsetse yakareba ine ruzha rwekudzivirira kupfuura RS232 zvishandiso ndechekuti yakaenzana inosiyanisa drive nzira inoshandiswa. Mune yakaringana mutsauko system, voltage inogadzirwa nemutyairi inoonekwa nepakati pewaya. Mutyairi wemutsara wakadzikama anoburitsa musiyano voltage kubva +2 kusvika +6 volts kumativi ayo anobuda materminal. Mutyairi wemutsara wakadzikama anogona zvakare kuve neinopinza "gonesa" chiratidzo chinobatanidza mutyairi kune ayo anobuda materminal. Kana chiratidzo che "gonesa" chiri OFF, mutyairi anobviswa kubva pamutsetse wekutumira. Iyi yakabviswa kana kuremara mamiriro anowanzo kunzi "tristate" mamiriro uye anomiririra yakakwira impedance. Vatyairi veRS485 vanofanirwa kuve nekutonga uku. Vatyairi veRS422 vanogona kunge vaine kudzora uku asi hazviwanzo kudiwa. Mutambi wemutsara wakaenzana anonzwa voltage mamiriro emutsetse wekutumira pamitsetse miviri yekupinza chiratidzo. Kana iyo differential input voltage yakakura kudarika +200 mV, inogamuchira ichapa chaiyo logic mamiriro pane yakabuda. Kana musiyano voltage kupinza iri pasi pe -200 mV, iyo inogamuchira ichapa yakatarisana logic mamiriro pane ayo akabuda. The maximum operating voltage renji inobva ku +6V kusvika -6V ichibvumira vhoriyamutage attenuation inogona kuitika patambo refu dzekutumira.

A maximum common mode voltage chiyero che +7V inopa yakanaka kudzivirirwa kweruzha kubva voltages inoturikirwa pamitsetse miviri yakamonyoroka. Iyo chiratidzo chepasi mutsara yekubatanidza inodiwa kuitira kuchengetedza yakajairika modhi voltage mukati mechikamu ichocho. Dunhu rinogona kushanda pasina kubatana kwepasi asi rinogona kunge risingavimbike.
