Note1) Switching between 100BASE-TX and 10BASE-T is done automatically by auto negotiation
function.
Note2) The standards cite 10 m as the maximum, but noise resistance measures such as attaching a
ferrite core may be necessary in some cases, depending on the usage environment. Also, if the
hub is positioned close to a control board, we recommend using it at a distance of 10 m or less.
Note3) The standards cite 50 m as the maximum, but noise resistance measures such as attaching a
ferrite core may be necessary in some cases, depending on the usage environment. Also, if the
transceiver is positioned close to a control board, we recommend using it at a distance of 5 m or
less.
