Nā memo:

1. ʻAʻole hoʻohana ʻia ʻo TX Fault a hoʻopaʻa mau ʻia i ka lepo ma o kahi pale pale 100 ohm.

2. ʻAʻole pili ʻo TX Disable e like me ka wehewehe ʻana ma ka MSA i ka module 1000BASE-T, akā hoʻohana ʻia no ka maʻalahi ma ke ʻano he mea hoʻokomo e hoʻihoʻi i ka ASIC kūloko.Huki ʻia kēia pine i loko o ka module me kahi pale 4.7 KW.

Haʻahaʻa (0 - 0.8 V): Hoʻomaka ka mea lawe uila

Ma waena (0.8 V a me 2.0 V): ʻAʻole wehewehe

Kiʻekiʻe (2.0 – 3.465 V): Transceiver ma ke kūlana hoʻihoʻi
