WIRING
This chapter shows the wiring methods to a C Controller module.
The bend radius of the cable near the connector or port should be at least four times longer than the cable's
outside diameter.

Ethernet Ports

This section shows the specification of a usable Ethernet cable and its wiring.
Ethernet cable
The following shows the specifications of the cables that can be used for connection with peripherals by using the Ethernet
ports (CH1 and CH2). Cables compliant with IEEE802.3 10BASE-T/100BASE-TX/1000BASE-T standards can be used.
Transmission rate
1000 Mbps
100 Mbps
10 Mbps
How to connect an Ethernet cable
1.
Check the insertion direction, and insert an Ethernet cable into the Ethernet port on the C Controller module until it clicks.
2.
Check if the cable is securely connected by pulling it slightly.
3.
Check that the SPEED LED of the Ethernet port 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.
• The SPEED LED is turned OFF when connecting with an Ethernet device on the network of which the
transmission rate is 10 Mbps. Check the communication state by executing the PING test, etc.
How to disconnect an Ethernet cable
1.
Pull out the Ethernet cable while pinching a clip on the connector.
