Hāʻawi ke kikowaena port serial i ka hana o ka port serial i ka Pūnaewele, hiki ke hoʻololi i ka RS-232/485/422 serial port i loko o kahi kikowaena TCP/IP, a mālama i ka lawe ʻana i nā ʻikepili helu ʻelua ma waena o ka RS-232. /485/422 port serial a me ke kikowaena pūnaewele TCP/IP.E paipai i nā polokalamu serial e loaʻa koke ke kuleana o ke kikowaena pūnaewele TCP/IP, ka pilina pūnaewele e hoʻokō i ke kamaʻilio ʻikepili, a hoʻonui nui i ka mamao kamaʻilio o nā polokalamu serial.

Nui nā mea hana kuʻuna e like me POS, ATM, nā mea heluhelu kāleka, nā mea heluhelu kāleka, nā hoʻololi, nā wahie dispensers, RTUs, CNC machine tool, mea ho'āʻo, etc. 422/RS- Serial interface e like me 232/RS-485.He nui nā huahana JHA Technology, ka mea nui e ʻike i ka lawe ʻana i ka ʻikepili ma waena o Ethernet a me nā puka makani like ʻole, i hiki ke maʻalahi a maʻalahi nā mea hiki ʻole ke komo i ka Pūnaewele i ka pūnaewele, a ʻike i ka hoʻokele pūnaewele a me ka mana mamao.

No ka laʻana, hoʻohana ka hapa nui o nā ʻōnaehana hoʻokele kaʻa i nā loulou kaʻa, pōkole ka mamao kamaʻilio o ke kaʻa, a paʻakikī ke uwea.He kumukūʻai kiʻekiʻe ke ʻano hou o TCP/IP network access control machine a ʻaʻole kūpono me nā ʻōnaehana hoʻokele maʻamau.A pono mākou e hoʻohana i kahi kikowaena serial kūpono, hiki ke hoʻololi ʻia ka mana komo ʻana i kahi mana TCP/IP network access control, a hiki ke hoʻokō ʻia ka hoʻokele mamao ma ke kumu kūʻai haʻahaʻa.
