ʻOi aku ka maikaʻi o ka Rs485 a i ka Rs232 Serial Converter - E1-4 Channel RS232/RS422/RS485 Converter JHA-CE1D4/R4/Q4 – JHA

E1-4 Kanal RS232/RS422/RS485 mea hoʻololiJHA-CE1D4/R4/Q4

Nānā nui

Hoʻokumu ʻia kēia mea hoʻololi hoʻololi ma FPGA, e hāʻawi ana i ka 4Channel RS232/485/422 ka hoʻouna ʻana ma ka interface E1. Hoʻokaʻawale ka huahana ma o nā kūʻē ma waena o ka mamao o ke kamaʻilio serial interface a me ka helu kamaʻilio, ʻokoʻa, hiki iā ia ke hoʻonā i ka hoʻopili electromagnetic, ke komo ʻana o ke apo honua a me ka pōʻino uila. Hoʻomaikaʻi nui ka mea hana i ka hilinaʻi, palekana a me ka hūnā o ka kamaʻilio ʻikepili. Hoʻohana nui ʻia ia no nā ʻano ʻenehana like ʻole, ka mālama ʻana i ke kaʻina hana a me nā manawa hoʻokele kaʻa, ʻoi aku hoʻi no ka Bank, a me Power a me nā ʻāpana ʻē aʻe a me nā ʻōnaehana i loaʻa nā koi kūikawā o ke kaiapuni electromagnetic interference. Hiki iā RS232/RS485/RS422 ke hoʻoili i ka ʻikepili serial adaptable asynchronously 0Kbps-57600Kbps baud rate.
