Ethernet Connector

This section shows the wiring for an Ethernet connector.
Ethernet cable and hub
Use an Ethernet cable and hub that meet the following conditions.
■Ethernet cable
Standard Specification
1000BASE-T Category 5e or higher, straight cable (shielded, STP)
Category 5e or higher, crossover cable (shielded, STP)
100BASE-TX Category 5 or higher, straight cable (shielded, STP)
Category 5 or higher, crossover cable (shielded, STP)
10BASE-T Category 3 or higher, straight cable (shielded, STP)
Category 3 or higher, straight cable (UTP)
Category 3 or higher, crossover cable (shielded, STP)
Category 3 or higher, crossover cable (UTP)
■Hub
Use a hub that can handle the communication speed in an Ethernet configuration.
1000BASE-T/100BASE-TX/10BASE-T, and full-duplex/half-duplex communication mode are identified by an
Ethernet-equipped module depending on the hub. For connection with a hub not having the auto-negotiation
function, set the setting on the hub side according to the communication mode.
Wiring procedure
■Connection
1.
Check the insertion direction, and insert an Ethernet cable into an Ethernet connector of this product until it clicks.
2.
Lightly pull the Ethernet cable to check that it is securely connected.
3.
Check that the SPEED LED for the Ethernet connector is ON.
• The time required from when an Ethernet cable is connected to when the SPEED LED turns ON may vary.
Normally, it turns ON in a few seconds. However, it may take longer because the linking-up processing is
repeated due to the device condition on the line.
• When the SPEED LED does not turn ON, check if the connected Ethernet cable has any failure. Replacing
the cable may solve this problem.
• The SPEED LED turns OFF when connecting with an Ethernet device on the network the communication
speed of which is 10 Mbps. Check the communication status by performing the PING test, etc.
■Disconnection
Pull out the Ethernet cable while pinching a clip on the connector.
