ABB 23WT21 GSNE002500R5101 CCITT V.23 Imodemu
Imodemu ye-ABB 23WT21 GSNE002500R5101 CCITT V.23 iyimodemu yezinga lezimboni eyakhelwe ukuxhumana okuthembekile phakathi kwamabanga amade kusetshenziswa izintambo zocingo ze-analog. Isekelwe ezingeni le-CCITT V.23, i-frequency shift keying (FSK) esetshenziselwa ukudluliswa kwedatha, ikakhulukazi ezinhlelweni zokusebenza zokuqapha nokulawula okukude. Imodemu isetshenziswa ezinhlelweni ezishintshayo zezimboni ezidinga ukuxhumana ngemigqa yocingo ye-analog yamabanga amade.
Imodemu ye-23WT21 isuselwe ku-CCITT V.23 ejwayelekile, isikimu sokumodemu esaziwayo esiklanyelwe ukudluliswa kwedatha ngemigqa yocingo yezinga lezwi. Izinga le-V.23 lisebenzisa i-frequency shift keying (FSK) ukunika amandla ukudluliswa kwedatha okuthembekile ngisho naphezu koxhumano olude lwefoni ye-analogi.
Isekela amanani edatha angu-1200 bps endaweni engezansi thola isiqondiso kanye nama-bps angu-75 endaweni yokudlulisela phezulu. Isekela ukuxhumana kwe-half-duplex, lapho idatha ingadluliselwa ohlangothini olulodwa ngesikhathi, kusukela kuyunithi ekude kuya esiteshini esimaphakathi noma ngokuphambene nalokho. Lokhu kuvamile kuzinhlelo zokusebenza ze-telemetry noma ze-SCADA, lapho amadivayisi ngezikhathi ezithile athumela idatha noma ulwazi lwesimo kusistimu emaphakathi.
Imodemu ye-23WT21 iklanyelwe ukuxhumana nezinhlobo ezahlukene zama-RTU noma ama-PLC ukuze inikeze amandla okuxhumana ngemigqa yocingo ye-analog. Ingahlanganiswa nezinhlelo zokulawula ze-ABB nezinye izisetshenziswa ezishintshayo zezimboni, futhi ihambisana namadivayisi adinga ukuxhumana okuthembekile kwe-serial.
Imibuzo evame ukubuzwa ngomkhiqizo imi kanje:
-Iyiphi iphrothokholi yokuxhumana esetshenziswa imodemu ye-ABB 23WT21?
Imodemu ye-ABB 23WT21 isebenzisa indinganiso ye-CCITT V.23, esebenzisa i-frequency shift keying (FSK) ukuze ixhumane ngemigqa yocingo ye-analog.
-Yisiphi isivinini sokudluliswa kwedatha imodemu ye-ABB 23WT21 isekela?
Imodemu isekela ama-bps angu-1200 ezansi komfula kanye nedatha yokudlulisa engu-75 bps ekhuphuka nomfula, okuyizivinini ezijwayelekile zokuxhumana okuyingxenye ye-duplex.
-Ngiyixhuma kanjani imodemu ye-ABB 23WT21 kulayini wefoni?
Imodemu ixhuma kulayini wefoni we-analog ejwayelekile (POTS). Vele uxhume ijekhi yefoni yemodemu kulayini wocingo, uqinisekise ukuthi ulayini awuphazamiseki.
