ABB 23WT21 GSNE002500R5101 CCITT V.23 Modem
Imodem ye-ABB 23WT21 GSNE002500R5101 CCITT V.23 yimodem yebakala loshishino eyenzelwe unxibelelwano oluthembekileyo kwimigama emide usebenzisa imigca yefowuni ye-analog. Isekelwe kumgangatho weCCITT V.23, i-frequency shift keying (FSK) imodulation esetyenziselwa ukuhanjiswa kwedatha, ngokukodwa ekubekweni kweliso kunye nokulawula izicelo. Imodem isetyenziswa kwiisistim ezizisebenzelayo zoshishino ezifuna ukunxibelelana kwimigca yefowuni ye-analog yomgama omde.
I-modem ye-23WT21 isekelwe kumgangatho weCCITT V.23, iskim esaziwayo sokumodareyitha esenzelwe ukuhanjiswa kwedatha kwimigca yefowuni yelizwi. Umgangatho we-V.23 usebenzisa i-frequency shift keying (FSK) ukunika amandla ukuhanjiswa kwedatha ethembekileyo nangaphezulu komnxeba we-analog yomgama omde.
Ixhasa amaxabiso edatha ye-1200 bps kwindawo esezantsi ifumana isikhokelo kunye ne-75 bps kwicala lokuhambisa umlambo. Ixhasa unxibelelwano lwe-half-duplex, apho idatha inokudluliselwa kwicala elinye ngexesha, ukusuka kwiyunithi ekude ukuya kwisikhululo esiphakathi okanye ngokuphambene noko. Oku kuqhelekileyo kwi-telemetry okanye kwizicelo ze-SCADA, apho izixhobo zithumela rhoqo idatha okanye ulwazi lwesimo kwinkqubo ephakathi.
Imodem ye-23WT21 yenzelwe ukusebenzelana neentlobo ezahlukeneyo ze-RTUs okanye ii-PLCs ukubonelela ngezakhono zonxibelelwano kwimigca yefowuni ye-analog. Inokuthi idityaniswe neenkqubo zokulawula i-ABB kunye nezinye izixhobo ezizisebenzelayo zoshishino, kwaye iyahambelana nezixhobo ezifuna unxibelelwano oluthembekileyo lwe-serial.
Imibuzo edla ngokubuzwa malunga nemveliso yile ilandelayo:
-Yeyiphi iprotocol yonxibelelwano esetyenziswa yimodem ye-ABB 23WT21?
Imodem ye-ABB 23WT21 isebenzisa umgangatho we-CCITT V.23, esebenzisa i-frequency shift keying (FSK) ukunxibelelana ngemigca yefowuni ye-analog.
-Sisiphi isantya sothumelo lwedatha exhaswa yimodem ye-ABB 23WT21?
Imodem ixhasa i-1200 bps ezantsi ukufumana idatha kunye ne-75 bps yokuhambisa idatha yokuhambisa phezulu, okuyizantya eziqhelekileyo zokunxibelelana kwesiqingatha se-duplex.
-Ndiyidibanisa njani imodem ye-ABB 23WT21 kumgca wefowuni?
Imodem idibanisa kumgca wefowuni ye-analog eqhelekileyo (POTS). Qhagamshela nje ijekhi yefowuni yemodem kumgca wefowuni, uqinisekise ukuba umgca ucacile ekuphazamiseni.
