Configuring the Ethernet Interface

The network settings of the ioPAC RTU controller can be modified with the serial console, or online over the network.

Modifying Network Settings with the Serial Console

In this section, we use the serial console to configure network settings of the ioPAC.

First, use the command

#cd /etc/network

to change to the directory where the network’s configuration files are located. root@Moxa:# cd /etc/network/ root@Moxa:/etc/network/#

Call up the vi text editor to begin editing the interfaces configuration file by typing:

#vi interfaces

You can configure the ioPAC RTU controller’s Ethernet ports for static or dynamic (DHCP) IP addresses.
