S485/232/422 rangatū whatunga mowhiti whaiaro-whakaora whatu transceiver whakarato 2 RS485 tauranga ranei 1 RS232 tauranga mō te kōrero rua i runga i te whatunga muka mowhiti i te wa ano. Kotahi anake te teihana matua e whakaaetia ana i roto i te kupenga mowhiti, ko etahi atu he teihana taurekareka; Ka taea e ia taputapu te mahi i roto i te aratau ariki, i te aratau pononga ranei. I muri mai, ka hoatu e JHA Technology ki a koe he korero whakataki mo te RS485 / 232/422 rangatū whakakai whakawhanaunga whatu whatu, me titiro!

Ko te RS485/232/422 whatunga mowhiti rangatū whakaora whaiaro whatu transceiver ngā o rua kōwae whatu ki te hanga i te rua-mowhiti whaiaro whakaora whatu whatunga mowhiti muka. I roto i te whatunga mowhiti kotahi, te ngoikore o nga taputapu, te ngoikore o te hiko, te pakaru ranei o te muka kaore e pa ki te mahi noa o etahi atu taputapu; Ko tenei hua e pai ana mo te whakawhitiwhitinga ahumahi ahumahi, te whakawhitiwhiti RS485 i roto i te taiao hiko matatini, te whakawhitinga taputapu RS485 tawhiti-tawhiti, te whatunga tango raraunga mita hiko me etahi atu punaha mahi e hiahia ana ki nga whakaritenga pono. Ka pakaru te muka ki tetahi waahi, ka rahua ranei tetahi pona, ka huri aunoa nga taputapu ki te whakawhiti korero kia kore ai e aukati te hononga korero, ka tino pai ake te haumaru me te pono o te whatunga korero.

485 transceiver whatu whakarato te mahi o RS-232/485/422 tauranga rangatū ki te muka whatu ki te ite i te rua-ara whakawhiti marama o raraunga i waenganui i muka whatu me RS-232/485/422 tauranga rangatū.

Na te roa o te tukunga o te muka whatu (maha-aratau 2KM, kotahi-aratau ki runga ki te 20, 40, 60KM) me te kaha ki te aukati i te aukati, koinei te mea pai rawa atu mo te tuku tawhiti ki te hono atu i te waahanga kapeka mamao ki te manaaki. me te tohatoha i te punaha whakahaere pokapū. Ma te kaha ki te aukati i te aukati, ka taea e ia te karo i te kino o nga taputapu whakawhitiwhiti raraunga ahumahi me te pokanoa o nga raina korero penei i te uira, nga pupuhi me te aukati hiko, me te whakarite i te pumau o te punaha korero.
