Abb 23wt21 gsne002500r5101 ccitt v.23 modem
I-ABB 23wT21 GSNE002500R5101 CCITT V.23 Modem iyimodemu yebanga lezimboni elenzelwe ukuxhumana okuthembekile kumabanga amade asebenzisa imigqa yocingo ye-analog. Kususelwa ku-CCITT V.23 ejwayelekile, ukuguquguquka okuvame ukuguquguquka (i-FSK) ukuguquguquka okusetshenziselwa ukuhanjiswa kwedatha, ikakhulukazi ekuqaphelweni okukude kanye nokulawula izinhlelo zokusebenza. Imodemu isetshenziswa ezinhlelweni ezenzakalelayo zezimboni ezidinga ukuxhumana ngemigqa yocingo ende ye-analog.
Imodemu engu-23ww21 isuselwe ku-CCITTV V.23 ejwayelekile, uhlelo oluhle elaziwayo lokushintshanisa olwenzelwe ukudluliswa kwedatha ngaphezulu kwemigqa yocingo lwe-Voice. I-V.23 Standard isebenzisa imvamisa i-Shift Shift ukunika amandla ukudluliswa kwedatha okuthembekile ngisho nangaphezulu kokuxhumeka kwezinombolo zefoni ezinde ze-Analog.
Ixhasa amanani edatha we-1200 bps ku-Downstream Thola ukuqondiswa kanye ne-75 bps ku-Upstream udlulise indlela. Ixhasa ukukhulumisana okunama-Half-duplex, lapho idatha ingadluliselwa khona ngasikhathi sinye ngasikhathi, kusuka kuyunithi elikude liye esiteshini esimaphakathi noma okuphambene nalokho. Lokhu kujwayelekile kuzinhlelo zokusebenza ze-telemetry noma ze-scada, lapho amadivaysi ethumela khona ngezikhathi ezithile imininingwane noma isimo solwazi ohlelweni oluphakathi.
Imodemu engu-23WT21 yakhelwe ukuxhumana nezinhlobo ezahlukahlukene ze-RTUS noma ama-PLCs ukuhlinzeka ngamakhono okuxhumana ngaphezulu kwemigqa yocingo ye-analog. Ingahlanganiswa nezinhlelo zokulawula i-ABB neminye imishini ye-automation yezimboni, futhi iyahambisana namadivayisi adinga ukuxhumana okuthembekile kwe-serial.
Imibuzo ebuzwa njalo mayelana nomkhiqizo imi ngale ndlela elandelayo:
-Ukusetshenziswa kwe-Modem 23www2w211?
Imodemu ye-ABB 23ww21 isebenzisa i-CCITT V.23 ejwayelekile, esebenzisa imvamisa i-Shift Shift Ukuhlehlisa (i-FSK) ukuxhumana ngezintambo zocingo ze-analog.
-Ileveli yokuhambisa idatha eyekela nge-ABB 23ww211 Modem?
I-Modem isekela ama-1200 BPS phansi athola idatha kanye ne-75 bps upstream datha idatha, okuyijubane elijwayelekile lokuxhumana ngesigamu.
-Ukuxhumanisa kanjani imodemu ye-ABB 23ww21 kulayini wezingcingo?
Imodemu ixhumeka kulayini ojwayelekile we-analog (amabhodwe). Mane nje uxhume ngocingo lwemodemu kulayini wezingcingo, uqiniseke ukuthi umugqa ucacile wokuphazanyiswa.
