Cisco 2802 - CAPWAP to Mobility Express

[icttech1981]

I have a Cisco 2802 AP here which is running CAPWAP.

 

All our other AP's are Cisco 2602's so we don't have a controller onsite, thus I need to configure this so it is running Mobility Express.

 

There are a number of guides online as well as a few YouTube videos. I can connect to it using TFTP and Putty using a serial cable. I need to be able to login using the default credentials then I can follow the process to get Mobility Express installed, however the prompt to login quickly passes and then it enters discovery mode and starts looking for a controller.

 

Can anyone help? How can i get it to stop at the point it asks for credentials so i can enter them and begin to configure it?
