Rs485 ingoa nui Ki Itarangi - Kaitahuri atanga Itarangi V.35 JHA-CV1F1 – JHA

Itarangi V.35 atanga kaitahuriJHA-CV1F1

Tirohanga

Ko tenei Ethernet ki te V.35 kawa whakawhiti (whakawhitinga atanga) ma te whakamahi i te hoahoa FPGA nui, e whakarato ana i te atanga DTE / DCE V.35 me te atanga Ethernet, ka taea te whakatutuki i te 10 / 100Base-T Ethernet raraunga E1 whakawhiti i runga i te awa, he mahi nui. , piriti Ethernet ako whaiaro. Ko te taputapu hei toronga o te taputapu Itarangi ma te whakamahi i te hongere V.35 te whatunga o naianei (DDN, ISDN, ATM) e whakaratohia ana (pērā i te ngeru papawaewae), kia pai ai te utu iti o te hononga Ethernet i nga pito e rua. Ko nga taputapu whakamatautau i hangaia hei whakahaere i te whakatuwheratanga me nga mahi tiaki.

Whakaahua Hua

Momo paku

Ngā āhuatanga

• I runga i te IC mana-whaiaro , te ihirangi rorohiko teitei (te maramara kernel i runga i te rorohiko)
• Ko te atanga V.35 e whakarato ana i te momo DTE me te DCE: Ko te reiti DTE he 0 ki te 10M, ko te reiti DCE he nx 64k(N=1 ki te 32)
• Whakaratohia kia 2 nga mahi porowhita: rohe V.35 koropiko, rohe 10 Base-T koropiko.
• He pseudo matapōkere te mahi whakamatautau, ngawari te whakauru me te tiaki.
• Kōwhiringa tuku hiko: AC220V, DC-48V. Ko te tauranga pai me te kino ka taea te whakawhiti mo te DC-48V, he ngawari ki te whakauru
• Atanga kaiwhakahaere whatunga whakahaere SNMP
• Tukuna te Itarangi ki runga i te raina V.35
