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 he whakaritenga motuhake mo te taiao pokanoa hiko.Ka taea e te hongere RS232/RS485/RS422 te tuku i nga raraunga rangatū urutau ki te 512kbps te reiti baud.

Momo Mini

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 ki te 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
• Whakaratohia 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
