Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: With zvemagetsi yedzimudzangara maererano EIA-485, twisted vaviri netambo pamwe impedances pamusoro 150 ohms anoshandiswa bhazi topology. Bit rate inobva pa9.6 kbit/s kusvika pa12 Mbit/s inogona kushandiswa. Kureba kwetambo pakati pevadzidzisi vaviri kunogumira kubva pa100 kusvika ku1200 m, zvichienderana nehuwandu hwehuwandu hunoshandiswa. Nzira iyi yokutumira inonyanya kushandiswa nePROFIBUS DP.  Mubvunzo: Mukati mebhasi topology, yakawanda sei impedance (in ohms) ine tambo dzakapetwa mbiri?
150 ohms
