Twisted Pair vs Coaxial vs BS5308: Ko tēhea taura taputapu me whiriwhiri e koe?
- Te Whakautu Tika: Kāore he "Pai Rawa" Kotahi - Kei tō Tono
Ka pātai tonu te tangata:"He aha te momo taura taputapu pai rawa atu?"
Ko te whakautu māmā:Kāore he taura "pai" kotahi – ko te kōwhiringa tika kei runga i te momo tohu o tō waea, te tawhiti, te taiao hiko, me te rāngai ahumahi.

| BS5308 | Hinu me te hau, matū hinu, ngā wāhi morearea | Takirua miro + parepare + parenga ā-ringa + whakatauranga IS (puranga kikorangi) | Te utu nui ake; te taumaha ake; te nui rawa mō ngā ahumahi whānui |
Ko te Whakamutunga:Whakamahia te takirua miro mō te nuinga o ngā taputapu tukatuka (4-20mA, RS485). Whakamahia te coaxial mō te auau-teitei, te ataata rānei. Whakamahia te BS5308 ina hiahiatia e te whakatakotoranga - ko te tikanga mō ngā kaupapa hinu, hau, me te matū e hiahia ana ki te pakari ā-mīhini me te tiwhikete rohe morearea.
