I am not able to assign that IP address.
Kindly tell me any idea…
It’s going to depend if you are using an -S module(standard: digi plug and play firmware) or a -C module (custom: meaning you load your own firmware).
If you are using a -S module, you can download the digi discovery software (www.digi.com/support) and change the IP address that way.
If you are using the -C module, you might be able to communicate with it via the serial port when it boots up, thus changing the IP address that way.
