[Aipu-Watton] Ni irihe tandukaniro riri hagati ya rs232 na rs485?

Itumanaho ryitumanaho ryumurongo rigira uruhare rukomeye muguhuza ibikoresho no guhana amakuru. Ibipimo bibiri byakoreshejwe cyane niRs232kandiRs485. Reka dushuke mu itandukaniro ryabo.

· Rs232Protocole

TheRs232Imigaragarire (izwi kandi nka Tia / Eia-232) yagenewe kugenzura itumanaho ryuzuye. Yorohereza amakuru atemba hagati yibikoresho byamakuru (DTE), nka terminal cyangwa ikwirakwiza, nibikoresho bya Data (DCE). Hano hari ingingo zingenzi zijyanye na rs232:

1. Uburyo bwo gukora:

   • Rs232inkunga zombibyuzuye-duplexkandiigice cya duplexUburyo.
   • Muburyo bwuzuye-duplex, amakuru arashobora koherezwa kandi yakiriwe icyarimwe akoresheje insinga zitandukanye zo kwanduza no kwakirwa.
   • Muri kimwe cya kabiri-Duplex Mode, umurongo umwe utanga byombi kohereza no kwakira imirimo, kwemerera kimwe icyarimwe.

2. Intera itumanaho:

   • Rs232 irakwiriyeIntera ngufikubera imbogamizi mu mbaraga zo kwerekana ibimenyetso.
   • Kurenza urugendo rushobora kuvamo gutesha agaciro.

3. Inzego za Voltage:

   • Rs232 ikoreshaurwego rwiza kandi rwiza voltagekubimenyetso.

4. Umubare w'imibonano:

   • Umugozi wa rs232 mubisanzwe bigizwe naIntsinga 9, nubwo bamwe mubihuza bashobora gukoresha insinga 25.
