Inta jeer ee la habeeyey ee KingtoneVHFKanaalka XulashadaCod-weyneeye Bi jiho ah (BDA)waa xalal qiimo leh oo la isku halayn karo oo loogu talagalay in lagu kordhiyo oo lagu hagaajiyo aagga caymiskaVHFnidaamyada isgaarsiinta intercom.Kanaalka Xulashada BDAs waxay u ogolaataa isticmaalaha inuu ku kordhiyo sidayaal la rabo oo kaliya labada jiho, kor u kaca iyo hoos-u-dhaca.Xulashada kanaalka waxa lagu barnaamijayn karaa gudaha gudaha RS 232 ama meel fog oo loo maro Modem ama RJ45.
XUSUUS
Fiiro gaar ah 1: Awood wax soo saarka nidaamka waa shaqo ka mid ah tirada shilka sideyaasha ee nidaamka, heerka signalka kuwan s ilaa
habka kor u qaadida calaamadaha, faa'iidada PA's, iyo galinta luminta filtarrada gudaha nidaamka laba jiho.
Xusuusin 2: Jaantuska Buuqa Nidaamka waa wadarta cod-weyneeye NF iyo khasaaraha shaandhada ka hor cod-weyneeye.shaandhada luminta a re ku tiirsan
Balaadhka baasabka ee soo noqnoqoshada kor isku xidhka ah, ballaca baska ee soo noqnoqoshada xidhiidhka hoose, iyo joogsiga joogsiga dhexdooda.
Joogitaanka VHF Repeater BDA waxay siisaa nidaamka isgaadhsiinta intercom oo leh heerka deggenaanshaha kanaalka sare, maadaama caymiska la dheereeyay oo ka baxsan caymiska goobta.Codsiyada caadiga ah ee khadkan booters waa xaaladaha gudaha sida tunnelyada, dhismayaasha, tareenada dhulka hoostiisa mara, iyo muuqaalada bannaanka sida garoommada, meelaha miyiga ah iyo magaalooyinka cufan.Sababtoo ah waa nidaam laba-laab ah oo qalab ah, si aad u badbaadiso qiimaha labanlaabida quudiyaha.
