5.3 Connecting to the Network
The following explains how to connect the Ethernet adapter to 10BASE-T/100BASE-TX networks.
Pay close attention to safety and use the Ethernet adapter properly.
1) Sufficient network knowledge and safety precautions are required when installing 10BASE-T or
100BASE-TX networks. Consult a specialist when connecting cable terminals or installing trunk line
cables, etc.
2) Use a connection cable conforming to the standards shown in Subsection 5.3.1.
Cautions regarding powering the hub, PLC and Ethernet adapter simultaneously.
On some hubs, for a fixed period of time immediately after powering up, even if packets are sent from the
Ethernet device, there are cases when packets are not sent to the external device. In this case, create a
sequence program that waits a sufficient amount of time after powering up before sending packets.
5.3.1 Applicable cable
The following should be used for the Ethernet cable.
*1. Shielded twisted pair cable.
• A straight cable is used. A cross cable can also be used when using direct connection (simple connection)
between the personal computer and the Ethernet adapter.
5.3.2 Connecting to the 10BASE-T/100BASE-TX network
This section explains how to connect the Ethernet adapter to the 10BASE-T, 100BASE-TX network.
The following shows the connection diagram for the twisted paid cable.
<Operating procedure>
(Step 1) Connect the twisted pair cable to the hub.
(Step 2) Connect the twisted pair cable to the Ethernet adapter.
1) The Ethernet adapter detects whether it is 10BASE-T or 100BASE-TX, and in full-duplex or half-duplex
transmission mode automatically according to the hub. (Auto detection function)
For connection to a hub without the auto detection function, set the half-duplex mode on the hub side.
2) For 10BASE-T or 100BASE-TX connection required devices and a sample system configuration, refer to
Section 3.2.
