Use the Rotary Switches
The module reads the rotary switches first to determine if they are set to a
valid number for the last portion of the IP address. Valid numbers range from
001…254.
When the switches are set to a valid number, the module’s IP address is
192.168.1.xxx (where xxx represents the number set on the switches). The
module’s subnet mask is 255.255.255.0 and the gateway address is set to
0.0.0.0.
The module does not have a host name assigned, nor does it use any Domain
Name System when using the rotary switch settings.
1. To reset the module to its initial out-of-the-box settings, reset the
switches to 888 and cycle power.
Do not use the 888 switch setting during normal module operation.
2. After cycling power with the switches set to 888, remove the module
and set the switches to their final value.
The software configuration determines the IP address when you set
the rotary switches to:
• a value other than 888.
•
the valid IP address values 001…254.
