PHD-11TC-33+
Tirohanga
Ko te tohu korero a PHD-11TC-33+ me te mahi whakamarumaru ngaru ka uru ki roto i te arai haumaru motuhake, ka taea te mohio ki nga korero e rua-ara o te tohu mamati RS-485 Half Duplex i te waahi kino me te waahi haumaru.
Ko tenei hua e hiahia ana ki te tuku hiko motuhake, a ka wehea te hiko, te whakauru me te whakaputa.
