Qoraalo:

1. Marka uu sarreeyo, natiijadani waxay muujinaysaa cillad laysar ah oo nooc ka mid ah. Hoos u dhacu wuxuu muujinayaa hawlgal caadi ah. Waana in kor loo soo jiido iyadoo la adeegsanayo iska caabin 4.7 – 10KΩ ah oo ku taal guddiga martida loo yahay.

2. TX disable waa qalab loo isticmaalo in lagu xiro wax soo saarka indhaha ee gudbiyaha. Waxaa lagu soo jiidaa gudaha module-ka iyadoo la adeegsanayo iska caabin 4.7 – 10KΩ ah. Xaaladihiisu waa:

Hoose (0 – 0.8V): Gudbiyuhu wuu shaqeeyaa (>0.8, < 2.0V): Lama qeexin

Sare (2.0V~Vcc+0.3V): Gudbiye Naafo ah Furan: Gudbiye Naafo ah

3. Mod-Def 0,1,2. Kuwani waa biinanka qeexida module-ka. Waa in lagu soo jiidaa iska caabin 4.7K – 10KΩ ah oo ku taal guddiga martida loo yahay. Danabka jiidista waa inuu u dhexeeyaa 2.0V ~Vcc + 0.3V.

Mod-Def 0 waxaa saldhig u ah module-ka si uu u muujiyo in module-ku uu joogo

Mod-Def 1 waa xariiqda saacadda ee is-dhexgalka taxanaha laba-silig ah ee aqoonsiga taxanaha ah

Mod-Def 2 waa khadka xogta ee is-dhexgalka laba-silig ee taxanaha ah ee aqoonsiga taxanaha ah

4. Marka uu sarreeyo, wax soo saarkani wuxuu muujinayaa luminta calaamadda (LOS). Hooseyntu waxay muujinaysaa hawlgal caadi ah.

5. RD+/-: Kuwani waa wax soo saarka kala duwanaanshaha qaataha. Waa khadadka kala duwan ee AC ee ku xiran 100Ω kuwaas oo lagu joojinayo 100Ω (kala duwanaansho) marka la isticmaalayo SERDES. Isku xirka AC waxaa lagu sameeyaa gudaha module-ka sidaas darteed looma baahna guddiga martida loo yahay.

6. TD+/-: Kuwani waa qalabka gudbinta kala duwan. Waa khadadka AC-ku xiran, oo leh 100Ω kala duwanaansho ah oo ku jira module-ka. Isku xirka AC-ga waxaa lagu sameeyaa gudaha module-ka sidaas darteed looma baahna guddiga martida loo yahay.
