To reset the module to its initial out-of-the-box settings, reset the switches to
888 and cycle power.
After cycling power with the switches set to 888, remove the module and set the
switches to their final value. When you set the rotary switches to a value other
than 888, or to the valid IP address values 001…254, the software configuration
determines the IP address.
IMPORTANT Do not use the 888 switch setting during normal module operation.
