2.2 Devices Required for Network Configuration

This section explains the devices that are required to configure a network.
Network installation work requires sufficient safeguard; ask a network specialist for
installation.
(1) Connection using the 100BASE-TX
2 - 2
When connecting FX -ENET to a network, either a 10BASE-T or 100BASE-TX
3U
can be used.
The Ethernet module detects whether it is 10BASE-T or 100BASE-TX, and the
full-duplex or half-duplex transmission mode according to the hub.
For connection to the hub without the auto detection function, set the half-duplex
mode on the hub side.
Twisted pair cable
Ethernet module
Use devices that satisfy the standards of IEEE802.3 and 100BASE-TX.
• Shielded twisted pair cable (STP cable), category 5
Straight cables can be used.
(Correct operation is not guaranteed if a crossed cable is used to connect to
an external device via the 100BASE-TX of the Ethernet module. However, it
is possible to use crossed cables to connect two Ethernet modules for data
communication or to connect an Ethernet module.)
• RJ45 jacks
• 100Mbps hub
Hub
* Up to 2 levels are allowed
for cascade connection
