You can use this procedure to connect the IOLM to the network.
1.
Securely connect one end of a shielded twisted-pair (Cat 5 or higher) M12 Ethernet cable to
either Ethernet port.
2.
Connect the other end of the cable to the network.
3.
Optionally, use the other Ethernet port to daisy-chain to another Ethernet device.
4.
If you did not connect both Ethernet ports, make sure that the unused port is covered with a
connector cap to keep dust and liquids from getting in the connector.
Note: Ethernet ports must have an approved cable or protective cover attached to the connector to
guarantee IP67 integrity.
