He 'heluhelu' file e wehewehe ana i ke kaʻina hana hoʻokomo o ka mea hoʻokele me nā mea hoʻokele. No exampi ka manawa i hoʻokomo pono ʻia nā mea hoʻokele no Windows 10, hiki ke ʻike ʻia ka papa ma ka Mana Pūnaewele e like me ka hōʻike ʻana ma ka Figure 2-2.
Hiki ke hoʻohana ʻia ka EVB-LAN7801-EDS e loiloi i ka LAN7801 USB Ethernet Bridge me nā ʻano Microchip PHY a me nā mea hoʻololi.
No exampe, me ka EVB-KSZ9131RNX papa loiloi i hoʻokomoʻia, hiki ke ho'āʻoʻia ka EVB ma keʻano he alahaka maʻalahi ma ka hoʻohuiʻana i ke awa USB i ka PC a me ke kelepona Network i ka papa kaikamahine. Ke hoʻohana nei i ke kelepona pūnaewele, hiki ke hoʻopili ʻia ka PC i kahi pūnaewele e hana i kahi hoʻāʻo ping.
