Publication 440R-IN078A-EN-P - January 2014
When you use the rotary switches to assign an address and set it to 001, the
interface gateway address is set to 0.0.0.0, and the subnet mask is
255.255.255.0. When you use the switches to assign an address and set it
between 002...254, the interface gateway address is set to 192.168.1.1.
No host name is assigned to the interface, nor do you need to use a Domain Name
System when using the switch settings.

than 254 excluding 888), the interface checks if you have previously enabled
DHCP.
