- Haeba u sebelisa sokete ea Ethernet ntle le transformer, etsa bonnete ba hore u rala karolo ea transformer ea potoloho hape.
- Nahana ka ho rala TCT ea transformer, GND e hokahantsoeng le RCT, le GND e amanang le khanyetso ea longitudinal ea TX le RX e le AGND sebakeng sa GND e tloaelehileng. Sena se thusa ho arola lets'oao la MDI ho sistimi ea GND lerata. Netefatsa hore sebaka sa AGND se seholo ka ho lekaneng kapa se kopanya AGND le tsamaiso ea GND haeba ho feta peletageo.
- Khetha boleng bo loketseng bakeng sa Option1, dampho hanyetsa ho hanyetsa ho lumellana ha motlakase (EMC). Khanyetso ena e lokela ho thibela lerata le tloaelehileng le tšitiso ea lerata la mefuta e fapaneng. Qoba ho sebelisa boleng ba khanyetso bo boholo haholo kaha bo ka baka phokotseho ea molumotagE-level le mathata a puisano a Ethernet.
Ka ho latela litaelo tsena, u ka netefatsa ts'ebetso le ts'ebetso e nepahetseng ea WIZnet Ethernet Chip.
