Tirohanga

Ko tenei kaitahuri atanga kei runga i te FPGA, e whakarato ana i te 1Channel RS232/485/422 te tuku i runga i 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. Ka taea e te hongere RS232/RS485/RS422 te tuku i nga raraunga rangatū urutau ki te 512kbps te reiti baud.

Ngā āhuatanga

• I runga i te mana-whaiaro IC
• Tautoko 3 atanga RS232, RS422, RS485, ka taea e koe te whakamahi kotahi anake, kaore e taea te whakamahi i nga atanga e toru i te wa kotahi
• 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 Rerekē): 6KV,Impedance (2 Ohm),CM(Aratau Common): 6KV, Impedance (2 Ohm) paerewa
