PHG-11TC-33*
Tirohanga
PHG-11TC-33* Ka taea e te kaiwhakawhanake tohu whakauru tohu korero te mohio ki nga korero e rua-ara o nga tohu mamati haurua-rua RS-485 i roto i te ruma whakahaere me te waahi. Ko te ara iahiko he tohatoha hiko mo nga taputapu i runga i te waahi (e whakaatuhia ana i te ripanga i raro nei).
Me whakakaha motuhake tenei hua, ka wehea te tuku hiko, te whakaurunga me te putanga.

Tuhipoka:
1. Ko te mahi tereina hiko he mahi whiriwhiri, me tohu nga kaiwhakamahi i te tikanga tuku hiko ina whakatakoto ota
Ko te kowhiringa o nga hononga hiko hiko ka tirohia ki te wharangi 89 o te "Annex"
