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.
