100BASE-T and 10BASE-T connections
Connect the UTP cable to the 100BASE-TX/10BASE-T connector (RJ45) on the front panel of the ET-
LAN unit.
UTP cable
-
Use Category 5 UTP cable. According to the ratings, Category 3 or better cable can be used with
10BASE-T, but we recommend that you use Category 5 UTP cable, which provides higher reliability.
-
According to the ratings, UTP cable can be up to 100 m in length, but considering noise resistance, we
recommend that you keep the cable under 10 m in length.
-
We recommend that you use shielded cable in environments where electrical noise is likely to be
generated.
External power supply terminal
The external power supply terminal is not used when 100BASE-TX and 10BASE-T are being used.
Earth
-
The F.G. pin of the external power supply terminal on the front of the unit is connected to the outer
metallic shell of the 100BASE-TX/10BASE-T connector (RJ45), or the outer metallic shell of the
10BASE5 (AUI) connector. These are also connected to the F.G. terminal of the power supply unit
through the backplane.
-
In an environment with a high noise level, the F.G. terminal should be grounded at a grounding
resistance of 100
Ω
or less.
