Rarangi Utu mo te Rs485 422 Kaitahuri - Rangatū ki te E1 Kaihuri JHA-CE1Q1 – JHA

E1-RS422 KaitahuriJHA-CE1Q1

Tirohanga

Ko tenei kaitahuri atanga kei runga i te FPGA, e whakarato ana i tetahi atanga E1 me tetahi atanga rangatū RS422. 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.
