Chapter 2 Install Your FLEX I/O Adapter
• For Firmware Revision 1.014, when the address switches are set to 001, the adapter gateway
address is set to 0.0.0.0. When the address switches are set to 002...254, the adapter
gateway address is set to 192.168.1.1.
The adapter does not have a host name that is assigned, or use any Domain Name System when
using the thumbwheel settings.
If you set the switches to an invalid number (such as 000, or a value greater than 254), the adapter
checks to see if you enabled DHCP.
