Ahu Hangarau
Whakataki Mahi
- Tautokohia te huringa aunoa i roto i te ipurangi, IDLE, me te PSM aratau ki te whakatutuki i te kohi hiko tino nui.
- Te tātari aunoa me te tukatuka o nga ahuatanga rereke, e whakarato ana i te whatunga NB-IoT pono me te pono te whakawhiti marama.
- Tautokohia te kawa UDP, te aratau UDP-ZSD i runga i te whakamaarama o te Hinengaro, te kawa China Telecom CoAP.
- Ma te whakamahi i te Mind's SDK, he maamaa ake te whanaketanga rorohiko kaihautu, a ka taea e koe te whakatu i to ake ake pokapu kaore he kaupapa TCP/IP.
- Tautokohia te whirihoranga tawhā rohe me te mamao me te whakamohoatanga firmware mamao.
- Tautokohia te putea rehitatanga ritenga, te putea ngakau, te putea pane ritenga, he watea mo nga kaiwhakamahi ki te whakauru i nga raraunga.
- Katoa te tautoko mo nga tono whirihoranga ahumahi, OPC Server (whakaritenga e hiahiatia ana), me nga tauranga rangatū mariko.
- He tautoko katoa mo Mind IoT Cloud, kaore nga kaiwhakamahi e hiahia ki te hanga i a raatau ake kaitoro.
- Tautokohia te maataki i te waa-tuipuu mo te mana whakahaere taputapu.
- Whakaratohia te atanga korero RS232, RS485, ko te reiti baud he kowhiringa mai i te 1200bps ki te 38400bps, a ko te moka timata/mutu moka/taurite he mea whiriwhiri.
- Ko te tuku hiko me te tauranga rangatū e mau ana i te whakamarumaru a te TVS ki te whakapumau i te pumau me te pono o nga taputapu.
- Tautokohia te whirihoranga kore utu o nga tohutohu kohinga tuhinga a-rohe kia mohio ai te DTU ki te kohi raraunga taputapu kaore he wawaotanga rorohiko manaaki.
- Tautokohia te hiko hiko o waho, te tatari roa i roto i te aratau kohi hiko iti.

Ka rere te taputapu me te iti o te kohi hiko me te kore e taea te whiwhi raraunga hono mai i te pokapū raraunga.
Me kaha te DTU ki te tuku i nga raraunga me te whakauru i te aratau hononga i mua i te tuku raraunga a te pokapū.
I muri i te kore korero raraunga, ka uru aunoa a MDN311 ki te aratau PSM ki te pupuri i te iti o te kohi hiko.
E tautoko ana a MDN311 i te mahi whakahōtaka tuhinga.Ka taea e nga kaiwhakamahi te whakarite i nga konae tuhinga ma te rorohiko whirihoranga whakairoiro o nga taputapu, kia kore ai e hiahiatia e nga tono i runga i te waahi etahi atu mana whakahaere, kaore hoki e hiahia ki te whakawhirinaki ki te papaaho raraunga ki te whakaputa i nga tohutohu kohinga hei whakatutuki i te hononga tika ki te taputapu.MDN311 Kohikohia nga raraunga mai i te taputapu me te tuku korero ki te papa.
Whakaritenga Whakahōputu Raraunga Raraunga Hangarau
Mōkī rēhita ritenga:Ka taea e nga kaiwhakamahi te whirihora noa i nga ihirangi o te paatete raraunga i tukuna i te wa tuatahi e hono ana a MDN311 ki te pokapū raraunga.
Mōkī tātaki manawa:Ka taea e nga kaiwhakamahi te whirihora noa i nga ihirangi o te paatete ngakau i tukuna e MDN311 ki te pokapū raraunga.
Mōkī pane ritenga:Ka taea e te kaiwhakamahi te whirihora i nga ihirangi motuhake i mua i te paatete raraunga ka tukuna e te DTU ki te pokapū raraunga kia mohio ai te momo raraunga, te waahanga ranei.
