ABB 23WT21 GSNE002500R5101 CCITT V.23 Modem
Modem ya ABB 23WT21 GSNE002500R5101 CCITT V.23 ndi modemu ya giredi ya mafakitale yomwe idapangidwa kuti izilumikizana modalirika pamatali ataliatali pogwiritsa ntchito mizere yafoni ya analogi. Zimachokera ku CCITT V.23 standard, frequency shift keying (FSK) yomwe imagwiritsidwa ntchito potumiza deta, makamaka pakuwunika ndi kuyang'anira ntchito zakutali. Modem imagwiritsidwa ntchito pamakina opanga makina omwe amafunikira kulumikizana pamizere yamafoni atalitali aanalogi.
Modem ya 23WT21 imachokera ku CCITT V.23 muyezo, ndondomeko yodziwika bwino yosinthira deta yomwe imapangidwira kufalitsa deta pamizere ya telefoni ya mawu. Muyezo wa V.23 umagwiritsa ntchito ma frequency shift keying (FSK) kuti athe kutumiza deta yodalirika ngakhale pamalumikizidwe amafoni a analogi ataliatali.
Imathandizira ma data a 1200 bps kunsi kwa mtsinje kulandira malangizo ndi 75 bps kumtunda wotumizira njira. Imathandizira kulumikizana kwa theka-duplex, komwe deta imatha kutumizidwa kunjira imodzi panthawi imodzi, kuchokera kugawo lakutali kupita ku siteshoni yapakati kapena mosemphanitsa. Izi ndizofala pamapulogalamu a telemetry kapena SCADA, pomwe zida zimatumiza nthawi ndi nthawi deta kapena zambiri zamachitidwe kugulu lapakati.
Modem ya 23WT21 idapangidwa kuti izilumikizana ndi mitundu yosiyanasiyana ya ma RTU kapena ma PLC kuti azitha kulumikizana ndi mizere yamafoni a analogi. Itha kuphatikizidwa ndi machitidwe owongolera a ABB ndi zida zina zamagetsi zamagetsi, ndipo imagwirizana ndi zida zomwe zimafunikira kulumikizana kodalirika kwa serial.
Mafunso omwe amafunsidwa pafupipafupi pazamalonda ndi awa:
-Kodi modemu ya ABB 23WT21 imagwiritsa ntchito njira yanji yolumikizirana?
Modem ya ABB 23WT21 imagwiritsa ntchito muyezo wa CCITT V.23, womwe umagwiritsa ntchito ma frequency shift keying (FSK) polumikizana ndi mizere ya foni ya analogi.
-Ndi liwiro lanji lotumizira ma data lomwe modemu ya ABB 23WT21 imathandizira?
Modem imathandizira ma 1200 bps kunsi kwa mtsinje kulandira deta ndi 75 bps kumtunda kufalitsa deta, yomwe ndi liwiro laling'ono la kulankhulana kwa theka-duplex.
-Ndimalumikiza bwanji modemu ya ABB 23WT21 ku foni yam'manja?
Modem imalumikizana ndi mzere wafoni wa analogi (POTS). Ingolumikizani jack ya foni ya modemu ku chingwe cha foni, kuonetsetsa kuti chingwecho sichikusokoneza.
