Rarangi Utu mo te Rs485 422 Kaitahuri - Rangatū ki te E1 Kaihuri JHA-CE1R1 – JHA

E1-RS232 KaitahuriJHA-CE1R1

Tirohanga

Ko tenei kaitahuri atanga kei runga i te FPGA, e whakarato ana i tetahi atanga E1 me tetahi atanga rangatū RS232, 1Channel RS232 tuku ma te atanga E1. Ka pakaru te hua na roto i nga tautohetohe i waenga i te tawhiti whakawhitiwhiti atanga rangatū tuku iho me te tere o te whakawhitiwhiti korero, hei taapiri, ka taea hoki te whakaoti i te pokanoa hiko, te pokanoa o te mowhiti whenua me te kino o te uira. Ko te taputapu ka tino whakapai ake i te pono, te haumaru me te noho muna o te whakawhitiwhiti korero raraunga. E whakamahia nuitia ana mo nga momo whakahaere ahumahi, whakahaere whakahaere me nga waa whakahaere waka, ina koa mo te Peeke, me te Hiko me etahi atu waahanga me nga punaha he whakaritenga motuhake mo te taiao pokanoa hiko. Ko te tere o te whakawhitiwhiti atanga rangatū ki te 512KBPS.

Ngā āhuatanga

• I runga i te mana-whaiaro IC
• He kaha ki te kite aunoa i te reiti baud o te tohu tauranga rangatū
• Whakamatauria aunoatia te take o te matt taputapu na te mea kua mate te taputapu, kua pakaru ranei te raina E1. Na ka tohu i runga i te LED.
• Atanga tauranga rangatū uira-tiaki i tae IEC61000-4-5 (8/20μS) DM(Aratau Rerekē): 6KV, Impedance (2 Ohm),CM(Aratau Common): 6KV, Impedance (2 Ohm) paerewa
• Whakaritea kia 2 nga herenga: 75 Ohm kore taurite me te 120 Ohm toenga;
• Tautoko Whakahaere Whatunga SNMP;
• Ka taea e te hongere rangatū te tuku raraunga rangatū urutau ki te 300 Kbps-921.6Kbps reeti baud
• Raraunga rangatū multiplexing i roto i E1 tautoko ITU-T R.111 aratau pekepeke waehere
