2019 Kounga Pai Rangatū Ki Itarangi Kaitahuri - E1-RS485 Kaihuri JHA-CE1D1 – JHA

E1-RS485 Tahurir JHA-CE1D1

Tirohanga

Ko tenei kaitahuri atanga kei runga i te FPGA, e whakarato ana i tetahi atanga E1 me tetahi atanga rangatū RS485, 1Channel RS485 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 e whai tikanga motuhake ana mo te taiao wawaotanga hiko. Ko te reiti whakawhitiwhiti atanga rangatū kei te 921.6KBPS.

Ngā āhuatanga

• I runga i te mana-whaiaro IC
• Ka taea te kite aunoa me te whakahaere i te rere raraunga RS-485 me te kore he tohu ruru ringaringa hei whakahaere i te ahunga rere o nga raraunga
• 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
• Whakaritea kia 2 nga herenga: 75 Ohm kore taurite me te 120 Ohm toenga;
• Tautokohia te 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
• Atanga tauranga rangatū uira-tiaki i tae IEC61000-4-5 (8/20μS) DM(Aratau Rerekētanga): 6KV,Impedance (2 Ohm), CM(Aratau Common): 6KV, Impedance (2 Ohm) paerewa
