Item	100BASE-TX	1)	100BASE-T	1)	100BASE5
Transmission speed	100Mbit/s		10Mbit/s		10Mbit/s
Transmission method	Base band		Base band		Base band
Max. segment length	100m note 2)		100m note 2)		500m
Max. distance between nodes	205m (2 segments)		500m (5 segments)		2500m (5 segments)
Communication cable or connection	Category 5 UTP cable		Category 3, 4 and 5 UTP cable		Transceiver cable
Max. transceiver cable					50m note 3)
length
Max. number of nodes					100 nodes/segment
Node spacing					Integer multiples of 2.5m

Notes: 1) Switching between 100BASE-TX and 10BASE-T is done automatically by auto negotiation function.

2)The standards cite 100m 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 10m or less.

3)The standards cite 50m 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 5m or less.
