Cov Lus Qhia Xaiv (Cov Lus Qhia Txog Engineering)
Match 120Ω impedance- zam teeb liab xav txog
Txiav ob qhov kawg- siv 120Ω resistors ntawm thawj thiab kawg ntawm
Hauv av ntws hlau ntawm ib qho chaw nkaus xwb- tiv thaiv av loops
Khaws nyob deb ntawm cov kab hluav taws xob- Yam tsawg kawg nkaus 300mm sib cais
Saib lub vojvoog khoov- 10 × cable OD yam tsawg kawg nkaus
Max 32 nodes- siv repeaters rau ntau dua
Cable ntev vs. baud tus nqi- khiav ntev dua=qis dua
Tsis txhob siv sab nraum zoov- ntsuas rau -20℃rau +75 degree, sab hauv tsev nkaus xwb
