■Connecting
1.
Power off the module power supply of the I/O module (waterproof module) and the power of the external device.
2.
Insert the Ethernet cable connector into the I/O module (waterproof module). Pay attention to the connector's orientation.
3.
Tighten the Ethernet cable connector.
4.
Power on the module power supply of the I/O module (waterproof module).
5.
Power on the external device.
6.
Check that P1 LINK LED/P2 LINK LED on the port into which the Ethernet cable is connected is on.
If P1 LINK LED/P2 LINK LED does not turn on, refer to the following and take a corrective action.
Page 195 When the P1 LINK LED or P2 LINK LED turns off
*1 The time taken for P1 LINK LED/P2 LINK LED to turn on after connection of the Ethernet cable may vary. The LINK LED normally turns
on in a few second. However, if link-up processing is repeated due to a condition of a device on the line, the longer time may be
required.
*2 When connecting a 100Mbps device to P1 and P2 of the I/O module (waterproof module) while the communication speed of the module
is 100Mbps, enable auto-negotiation of the device.
Both P1 and P2 connectors can be used.
• To use only one of them for star topology, either P1 or P2 can be connected.
• To use both of them for line topology and ring topology, P1-P1, P2-P2, and P1-P2 connections are possible.
■Disconnecting
1.
Power off the module power supply of the I/O module (waterproof module).
2.
Loosen the Ethernet cable connector and remove the cable.
