Upgrade Digiconnect ME -C module to -S module

Hi,
I by mistake ordered 15 nos. Digiconnect ME -C modules instead of -S modules. I don’t have NetOS development kit with me. I want to convert -C modules to -S modules. Can anyone please help and suggest me possible option for doing this?

thanks,
Sunil Jha

You can’t. I’ve talked to Digi about this once and they told me flat out that you need to exchange the modules.
